Adaptation improves neural coding efficiency despite increasing correlations in variability

Adibi, Mehdi; McDonald, James S.; Clifford, Colin W. G.; Arabzadeh, Ehsan

Description

Exposure of cortical cells to sustained sensory stimuli results in changes in the neuronal response function. This phenomenon, known as adaptation, is a common feature across sensory modalities. Here, we quantified the functional effect of adaptation on the ensemble activity of cortical neurons in the rat whisker-barrel system. A multishank array of electrodes was used to allow simultaneous sampling of neuronal activity. We characterized the response of neurons to sinusoidal whisker vibrations...[Show more]
