The relationship between gamma synchronization and neuronal discrimination performance. (A–C) Postadaptation change in gamma-band SFC influences the neurons’ ability to discriminate small changes in orientation. There is a significant and positive correlation between the gamma-band SFC after adaptation and the change in d′ that is specific to the supragranular layers. The color lines represent the linear regression fits associated with each cortical layer. (D) Analysis of lower frequency bands (<30 Hz) does not reveal a statistically significant correlation between the postadaptation change in SFC and the change in d′.
