Informational basis of sensory adaptation: Entropy and single-spike efficiency in rat barrel cortex

Arabzadeh, Ehsan; Adibi, Mehdi; Clifford, Colin W. G.


We showed recently that exposure to whisker vibrations enhances coding efficiency in rat barrel cortex despite increasing correlations in variability (Adibi et al., 2013). Here, to understand how adaptation achieves this improvement in sensory representation, we decomposed the stimulus information carried in neuronal population activity into its fundamental components in the framework of information theory. In the context of sensory coding, these components are the entropy of the responses...[Show more]
