Temporal Processing in Cat Primary Auditory Cortex

Abstract

In this short review, we discuss several aspects of how temporal coding is reflected in the response of primary auditory cortical neurons. We attempt to establish a link between several different temporal response properties including onset latency, response strength to repetitive stimuli, and the recovery of a response from suppression by a preceding signal. The results suggest a relationship between temporal effects that are expressed at quite different time scales. The results are discussed in relation to spatial representational properties and to coding in other sensory cortices.

Key Words:

• onset latency
• repetition transfer function
• forward masking.
