Two random but interesting papers on neurophysiology with behavior

Posted on October 15, 2023 by P.T.R. Rupprecht

Bagur, Bourg et al. (2022) from the Bathellier Lab in Paris make the interesting finding that the auditory code is represented as temporal sequences of neuronal activity in early auditory processing stages and as spatial patterns in auditory cortex. I … Continue reading →
