Methods A group of 18 patients with TGA performed an established real-space navigation paradigm, requiring allo- and egocentric spatial orientation abilities, 3 days (postacute stage) and 3 months (follow-up) after symptom onset. Visual exploration behavior and navigation strategy were documented by a gaze-controlled, head-fixed camera. Allo- and egocentric spatial orientation performance was compared to that of 12 age-matched healthy controls. Navigation-induced brain activations were measured using [18F]-fluorodeoxyglucose-PET in a subgroup of 8 patients in the postacute stage and compared to those of the controls. Results In the postacute stage, the patients navigated worse and had higher error rates than controls in allocentric (p = 0.002), but not in egocentric, route planning (p = 0.30), despite complete recovery of verbal (p = 0.58) and figural memory (p = 0.11). Until follow-up, allocentric navigation deficits improved, but higher error rates and reduced use of shortcuts persisted (p < 0.0001). Patients still exhibited relatively more fixations of unique landmarks during follow-up (p = 0.05). PET measurements during the postacute stage showed increased navigation-induced brain activations in the right hippocampus, bilateral retrosplenial, parietal, and mesiofrontal cortices, and cerebellar dentate nucleus in patients compared to controls (p < 0.005). Conclusions Patients with TGA show selective and prolonged deficits of allocentric spatial orientation. Activations in right hippocampal and extrahippocampal hubs of the cerebral navigation network functionally substitute for the deficit in creating and updating the internal cognitive map in TGA.}, language = {en} } @misc{BonhageHirschRaabetal., author = {Bonhage, Alexander and Hirsch, Florian and Raab, Thomas and Schneider, Anna and Raab, Alexandra and Ouimet, William}, title = {Characteristics of small anthropogenic landforms resulting from historical charcoal production in western Connecticut, USA}, series = {Catena}, volume = {195}, journal = {Catena}, issn = {0341-8162}, doi = {10.1016/j.catena.2020.104896}, pages = {14}, language = {en} } @misc{SchneiderHirschBonhageetal., author = {Schneider, Anna and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {The soil moisture regime of charcoal-enriched land use legacy sites}, series = {Geoderma}, volume = {366}, journal = {Geoderma}, issn = {0016-7061}, doi = {10.1016/j.geoderma.2020.114241}, pages = {15}, language = {en} } @misc{SchneiderBonhageRaabetal., author = {Schneider, Anna and Bonhage, Alexander and Raab, Alexandra and Hirsch, Florian and Raab, Thomas}, title = {Large-scale mapping of anthropogenic relief features—legacies of past forest use in two historical charcoal production areas in Germany}, series = {Geoarchaeology}, volume = {35}, journal = {Geoarchaeology}, number = {4}, issn = {1520-6548}, doi = {10.1002/gea.21782}, pages = {545 -- 561}, language = {en} } @misc{HirschSchneiderBonhageetal., author = {Hirsch, Florian and Schneider, Anna and Bonhage, Alexander and Raab, Alexandra and Drohan, Patrick J. and Raab, Thomas}, title = {An initiative for a morphologic-genetic catalog of relict charcoal hearths from Central Europe}, series = {Geoarchaeology}, volume = {35}, journal = {Geoarchaeology}, number = {6}, issn = {1520-6548}, doi = {10.1002/gea.21799}, pages = {974 -- 983}, language = {en} } @misc{BonhageHirschRaabetal., author = {Bonhage, Alexander and Hirsch, Florian and Raab, Thomas and Schneider, Anna and Raab, Alexandra and Ouimet, William}, title = {Stratigraphy and shape of relict charcoal hearths in Connecticut, USA}, series = {Anthropogenetische Geomorphologie - Geomorophologie im Anthropoz{\"a}n : Virtuelle Jahrestagung des Arbeitskreises f{\"u}r Geomorphologie 2020, 28./29.
