Utilizing Transcranial Alternating Current Stimulation and Functional Neuroimaging to Investigate Human Sensory Adaptation.

Sensory adaptation is the reduction of neural activity after repeated exposure to a stimulus. In a recent study, Kar et al. (2019) found that implementation of 10Hz-tACS to the human middle temporal cortex (hMT+) decreased sensory adaptation and increased functional connectivity. We explain the relevance of neuroimaging utilization with tACS and suggest different methods. Additionally, future directions are provided by introducing task-relevant oscillatory frequencies for tACS related to other sensory processes that undergo adaptation.
