Abstract

Sound sense The auditory cortex is thought to exhibit only transient responses to sound stimulation, which sits oddly with its role in processing complex sounds such as human speech and music. This paradox may now have been resolved. The experiments that gave rise to current views of mammalian auditory cortex were based on studies in anaesthetized animals. New work on the auditory cortex of awake marmosets shows that the neurons can discharge in a sustained manner for a prolonged period. It is possible to imagine how a sound picture can be built up: select neurons fire throughout the duration of the sound when it is their preferred stimulus, while the responses of other neurons fade away after the onset of to what, for them, is a non-preferred stimulus.
