To investigate this issue, we modulated OFA activity using transcranial direct current stimulation (tDCS). Method: In Experiment 1, participants performed a face detection task (the Mooney faces task) and a face discrimination task (the Composite faces task), which both assess holistic face processing. In Experiment 2, participants were asked to detect both Mooney faces and Mooney objects, to test face selectivity of OFA. In each experimental session, the tasks were presented once before (pre) and once after (post) administration of 20 min of excitability increasing anodal tDCS (real) and sham stimulation over the putative OFA. Results: Compared with sham stimulation, we found that real anodal tDCS interfered with both Mooney faces and objects detection, whereas it had no effect on holistic processing involved in face discrimination, as measured by the Composite faces task. Conclusions: Our results suggest that OFA is causally implicated in facial detection at least in degraded conditions (i.e., when the \"face\" signal needs to be extracted from a noisy background). In turn, our data do not implicate OFA in holistic processing in face discrimination. Finally, our data suggest a possible role of OFA in categorization of other nonface stimuli, a conclusion that must be taken with caution, as stimulation over OFA may affect object-selective adjacent regions."],["dc.description.sponsorship","Vigoni-DAAD grant"],["dc.identifier.doi","10.1037/neu0000127"],["dc.identifier.isi","000353905300008"],["dc.identifier.pmid","25110932"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37265"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Psychological Assoc"],["dc.relation.issn","1931-1559"],["dc.relation.issn","0894-4105"],["dc.title","The Role of the Occipital Face Area in Holistic Processing Involved in Face Detection and Discrimination: A tDCS Study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Objective: Here we have assessed safety aspects of this stimulation method by measuring neuron-specific enolase (NSE) levels, examining electroencephalogram (EEG) traces and analyzing anatomical data by using magnetic resonance imaging (MRI). Methods: Altogether 18 healthy volunteers participated in the study. tACS was applied at 5 kHz for a duration of 10 min over the left M1 at an intensity of 1 mA. Results: After stimulation no significant changes were detected in NSE levels, no structural alterations were observed in the anatomical scans and no pathological changes were found in the EEG recordings. Conclusions: Our data imply that the application of tACS is safe at least within these parameters and with these applied protocols. (C) 2014 Elsevier Inc.

To evaluate the role of these brain areas in declarative memory retrieval, we applied bilateral tDCS, with anode over the left and cathode over the right parietal or temporal cortices separately, during the recognition phase of a verbal learning paradigm using a balanced old-new decision task. In a parallel group design, we tested three different groups of healthy adults, matched for demographic and neurocognitive status: two groups received bilateral active stimulation of either the parietal or the temporal cortex, while a third group received sham stimulation. Accuracy, discriminability index (d’) and reaction times of recognition memory performance were measurements of interest. The d’ sensitivity index and accuracy percentage improved in both active stimulation groups, as compared with the sham one, while reaction times remained unaffected. Moreover, the analysis of accuracy revealed a different effect of tDCS for old and new item recognition. While the temporal group showed enhanced performance for old item recognition, the parietal group was better at correctly recognising new ones. Our results support an active role of both of these areas in memory retrieval, possibly underpinning different stages of the recognition process."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2015"],["dc.identifier.doi","10.1371/journal.pone.0123085"],["dc.identifier.gro","3151348"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11758"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8142"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Separating Recognition Processes of Declarative Memory via Anodal tDCS: Boosting Old Item Recognition by Temporal and New Item Detection by Parietal Stimulation"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
