AI has the power to bring revolutionary improvements to the world of technology not only in the field of computer science but also in other fields like medical sciences. Objectives: This paper assumes the adoption of appropriate AI engineering principals in previous studies, and focusses on providing a structured review of the impact of AI on human society and the individual human being as a technology user. Additionally, it opens a window on how the future will look like in terms of AI and personalised medicine. Methods: The paper employed a qualitative research approach and data were collected through a structured literature review. Twenty-three peer reviewed papers were identified and analysed in relation to their relevance to the study. Results: Previous studies show a positive impact on users' behaviour is expected in supporting their healthcare needs especially in decision-making, personalised treatment and future diseases prediction, and that integrating users in studying AI impact is essential to test possible implications of the technology. Conclusion: Results indicate that without a clear understanding of why patients need AI, or how AI can support individuals with their healthcare needs, it is difficult to visualise the kinds of AI applications that have a meaningful and sustainable impact the daily lives of individuals. Therefore, there is an emerging need to understand the impact of AI technology on users' behaviour to maximise the potential benefits of AI technology.}, language = {en} } @misc{GlasauerHausmannMacNeilage, author = {Glasauer, Stefan and Hausmann, Peter and MacNeilage, Paul R.}, title = {Statistics of natural head motion suggest different head motion priors for rest and movement}, series = {Bernstein Conference 2018}, journal = {Bernstein Conference 2018}, doi = {10.12751/nncn.bc2018.0132}, language = {en} } @misc{GlasauerSalmasiStemmler, author = {Glasauer, Stefan and Salmasi, Mehrdad and Stemmler, Martin}, title = {The synergy between neurotransmitter spillover and asynchronous release in information transmission}, series = {Bernstein Conference 2018}, journal = {Bernstein Conference 2018}, doi = {10.12751/nncn.bc2018.0209}, language = {en} } @misc{BasserehRattayGlasauer, author = {Bassereh, Hassan and Rattay, Frank and Glasauer, Stefan}, title = {A mathematical framework for vesicle release from a retinal bipolar cell}, series = {Bernstein Conference}, journal = {Bernstein Conference}, doi = {10.12751/nncn.bc2019.0209}, language = {en} } @misc{Glasauer, author = {Glasauer, Stefan}, title = {Sensorimotor control of smooth pursuit}, series = {Neuroscience 2018 Home}, journal = {Neuroscience 2018 Home}, abstract = {Interaction with the visual world critically depends on when and how we move our eyes. Eye movements, in turn, alter our experience of the world by selecting objects to foveate and tracking objects over time. The interaction between vision and eye movements continues indefinitely, one process modulating the strength and timing of the other. Despite this tight linkage, vision is often studied outside the context of eye movements, during stable fixation. Likewise, eye movements are often studied with sparse visual stimuli and under ideal viewing conditions. A more accurate understanding of vision requires studying perception in the context of eye movements. Different types of eye movements reveal different aspects of how the brain works. The continuous nature of tracking smooth pursuit eye movements, combined with its ubiquitous presence in natural vision, makes it an excellent system in which to analyze perception at fine spatial and temporal resolutions. For example, how does vision change during the transition from fixation to pursuit, and when does the brain allocate resources to account for these changes? In contrast, the ballistic nature of saccades requires analysis divided into discrete epochs, including well before the saccade during the planning stage, during saccade execution, and after the movement. At the neuronal level, how do heterogeneous populations of visual- and saccade-related cells come to represent a single saccade vector during these different epochs? What are the effects on visual perception when saccades and pursuit interact? This symposium will reveal how research incorporating both types of eye movements and visual perception can provide a more ecologically valid account of visual-motor integration and the intervening cognitive processes. This symposium will review innovative approaches and recent advances in understanding the interplay of eye movements and vision. We will take a multifaceted approach to understanding the effects of both exploratory (saccades) and tracking (smooth pursuit) eye movements on vision by using a range of methodologies and animal models (data-driven modeling, clinical populations, and simultaneous recordings of neuronal populations; humans, macaques, and marmosets). This symposium will appeal to vision scientists interested in selective attention, motion processing, neuronal modeling, motor control, neural circuits, and related topics.

However, we have but a sparse understanding of the neural processes involved during observational learning in naturalistic settings. Recently developed data driven methods for analyzing brain activity provide an opportunity for further investigation. Here, we evaluate intersubject synchrony during fMRI to understand common brain processes during naturalistic observational learning. Participants solitarily watched an instructional video and learned how to fold a paper figure. Three learning runs were sufficient to successfully solve the task. To assess interbrain synchrony, we extended previous principal component (PCA)-based methods to an intersubject principal component analysis (PCA), which offers multiple measures for additional insights into the nature of the synchrony. Using the different metrics of this method, we show a robust synchronous involvement of the action observation execution network (AOEN) in observational learning, between subjects as well as within subjects, regardless of the task or video content. Importantly, additional areas such as the cerebellum, primary motor cortex, control, and sensory integration areas also showed robust synchrony in observational learning. Complimentary to this robust general synchrony, individual regions of the AOEN exhibited task-related differences. Synchrony decreased during the learning process, likely reflecting task state and individual learning strategies. To test the stimulus as a possible source of synchrony, we quantified the temporal structure as the optic flow of the instructional video. Optic flow was strongly related to common activation of the somatomotor areas of the AOEN well beyond visual areas, but could not completely explain synchrony. Thus, although visual motion provides a proxy for meaningful hand actions, our results suggest that intersubject synchrony reflects common cognitive processing during observa- tional learning beyond sensory input.}, language = {en} } @misc{GlasauerShi, author = {Glasauer, Stefan and Shi, Zhuanghua}, title = {Individual beliefs about temporal continuity explain variation of perceptual biases}, series = {Scientific Reports}, volume = {12}, journal = {Scientific Reports}, issn = {2045-2322}, doi = {10.1038/s41598-022-14939-8}, abstract = {Perception of magnitudes such as duration or distance is often found to be systematically biased.

The main types of explanatory models proposed so far—static or iterative—mirror this distinction but cannot adequately explain individual biases. Here we propose a new unifying model that explains individual variation as combination of sensory precision and beliefs about temporal continuity and predicts the experimentally found changes in biases when altering temporal continuity.

Perfect compensatory movements would thus rotate the eyes exactly opposite to the head, that is, eyes vs. head would exhibit a unity gain. However, in many species, but also in elderly humans or patients with a history of vestibular damage, the aVOR is far from compensatory with gains that are in part considerably lower than unity. The reason for this apparent suboptimality is unknown. Here, we propose that low VOR gain values reflect an optimal adaptation to sensory and motor signal variability. According to this hypothesis, gaze stabilization mechanisms that aim at minimizing the overall retinal image slip must consider the effects of (1) sensory and motor noise and (2) dynamic constraints of peripheral and central nervous processing. We demonstrate that a computational model for optimizing retinal image slip in the presence of such constraints of signal processing in fact predicts gain values smaller than unity. We further show specifically for tadpoles of the clawed toad, Xenopus laevis with particularly low gain values that previously reported VOR gains quantitatively correspond to the observed variability of eye movements and thus constitute an optimal adaptation mechanism. We thus hypothesize that lower VOR gain values in elderly human subjects or recovered patients with a history of vestibular damage may be the sign of an optimization given higher noise levels rather than a direct consequence of the damage, such as an inability of executing fast compensatory eye movements.}, language = {en} } @misc{GlasauerStraka, author = {Glasauer, Stefan and Straka, Hans}, title = {Ear pins down evolution of thermoregulation}, series = {Nature}, journal = {Nature}, number = {607}, doi = {10.1038/d41586-022-01943-1}, pages = {661 -- 662}, abstract = {An analysis of fossil specimens of the inner ear helps to refine the timeframe of a key transition in vertebrate evolution — when our mammal-like ancestors began to regulate and maintain a high body temperature.}, language = {en} } @misc{KremmydaRettingerStruppetal., author = {Kremmyda, Olympia and Rettinger, Nicole and Strupp, Michael and B{\"u}ttner, Ulrich and Glasauer, Stefan}, title = {Teaching Video NeuroImages: Unilateral RIMLF lesion.

Such sequential dependence has been extensively studied in the visual domain, but less is known about its impact on time perception. Moreover, there are ongoing debates about whether these sequential biases occur at the perceptual stage or during subsequent post-perceptual processing. Using functional magnetic resonance imaging, we investigated neural mechanisms underlying temporal sequential dependence and the role of action in time judgments across trials. Participants performed a timing task where they had to remember the duration of green coherent motion and were cued to either actively reproduce its duration or simply view it passively. We found that sequential biases in time perception were only evident when the preceding task involved active duration reproduction. Merely encoding a prior duration without reproduction failed to induce such biases. Neurally, we observed activation in networks associated with timing, such as striato-thalamo-cortical circuits, and performance monitoring networks, particularly when a "Response" trial was anticipated. Importantly, the hippocampus showed sensitivity to these sequential biases, and its activation negatively correlated with the individual's sequential bias following active reproduction trials. These findings highlight the significant role of memory networks in shaping time-related sequential biases at the post-perceptual stages.}, language = {en} } @misc{RegnathBiersackJaegeretal., author = {Regnath, Franziska and Biersack, Katharina and J{\"a}ger, Nina and Glasauer, Stefan and Lehnen, Nadine}, title = {Not a general, symptom-unspecific, transdiagnostic marker for functional symptoms: sensorimotor processing of head control is intact in chronic pain}, series = {Frontiers in Neurology}, volume = {14}, journal = {Frontiers in Neurology}, issn = {1664-2295}, doi = {10.3389/fneur.2023.1294702}, abstract = {Introduction: Functional disorders are prevalent in all medical fields and pose a tremendous public health problem, with pain being one of the most common functional symptoms. Understanding the underlying, potentially unifying mechanism in functional (pain) disorders is instrumental in facilitating timely diagnosis, stigma reduction, and adequate treatment options. Neuroscientific models of perception suggest that functional symptoms arise due to dysregulated sensorimotor processing in the central nervous system, with brain-based predictions dominating the eventual percept. Experimental evidence for this transdiagnostic mechanism has been established in various functional symptoms. The goal of the current study was to investigate whether erroneous sensorimotor processing is an underlying transdiagnostic mechanism in chronic (functional) pain. Method: A total of 13 patients with chronic (functional) pain [three patients with chronic (functional) pain disorder, F45.40, ICD-10; 10 patients with chronic pain disorder with somatic and psychological factors, F45.41, ICD-10]; and 15 healthy controls performed large combined eye-head gaze shifts toward visual targets, naturally and with increased head moment of inertia. We simultaneously measured participants' eye and head movements to assess head oscillations at the end of the gaze shift, which are an established indicator of (transdiagnostic) sensorimotor processing deficits of head control. Results: Using a Bayesian analysis protocol, we found that patients with chronic (functional) pain and control participants stabilized their heads equally well (Bayes Factor 01 = 3.7, Bayes Factor exclusion = 5.23; corresponding to substantial evidence) during all sessions of the experiment.

A recent hypothesis based on the predictive coding theory of brain function suggests that in functional disorders, internal expectations do not match the actual sensory body states, leading to perceptual dysregulation and symptom perception. To test this hypothesis, we investigated the account of internal expectations and sensory input on gaze stabilization, a physiologically relevant parameter of gaze shifts, in functional dizziness. Methods: We assessed gaze stabilization in eight functional dizziness patients and 11 healthy controls during two distinct epochs of large gaze shifts: during a counter- rotation epoch (CR epoch), where the brain can use internal models, motor planning, and resulting internal expectations to achieve internally driven gaze stabilization; and during an oscillation epoch (OSC epoch), where, due to terminated motor planning, no movement expectations are present, and gaze is stabilized by sensory input alone. Results: Gaze stabilization differed between functional patients and healthy controls only when internal movement expectations were involved [F(1,17) = 14.63, p = 0.001, and partial η2 = 0.463]: functional dizziness patients showed reduced gaze stabilization during the CR (p = 0.036) but not OSC epoch (p = 0.26). Conclusion: While sensory-driven gaze stabilization is intact, there are marked, well- measurable deficits in internally-driven gaze stabilization in functional dizziness pointing at internal expectations that do not match actual body states.

In experimental isolation, the reflex is usually activated by motion of an achromatic large-field visual background with strong influence of radiance contrast on visual motion estimation and behavioral performance. The presence of color in natural environments, however, suggests that chromatic cues of visual scenes provide additional parameters for image motion detection. Here, we employed Xenopus laevis tadpoles to study the influence of color cues on the performance of the optokinetic reflex and multi-unit optic nerve discharge during motion of a large-field visual scene. Even though the amplitude of the optokinetic reflex decreases with smaller radiance contrast, considerable residual eye movements persist at the 'point of equiluminance' of the colored stimuli. Given the color motion preferences of individual optic nerve fibers, the underlying computation potentially originates in retinal circuits. Differential retinal ganglion cell projections and associated ocular motor signal transformation might further reinforce the color dependency in conceptual correspondence with head/body optomotor signaling.

Participants associated the words either sequentially with the previous word on the list, with spatial locations on a well-known path, or with unique autobiographical events.

During recall of words associated with autobiographical memories, the hippocampus might add spatiotemporal information supporting detailed scenic and contextual memories.}, language = {en} } @incollection{GlasauerKnorr, author = {Glasauer, Stefan and Knorr, Alexander G.}, title = {Physical Nature of Vestibular Stimuli}, series = {The Senses: A Comprehensive Reference, Volume 6: Vestibular System and Balance}, booktitle = {The Senses: A Comprehensive Reference, Volume 6: Vestibular System and Balance}, editor = {Fritzsch, Bernd and Straka, Hans}, edition = {2.
