  • Title: Brief and short-term corticofugal modulation of subcortical auditory responses in the big brown bat, Eptesicus fuscus.
    Author: Zhou X, Jen PH.
    Journal: J Neurophysiol; 2000 Dec; 84(6):3083-7. PubMed ID: 11110836.
    Abstract:
    Recent studies show that the auditory corticofugal system modulates and improves ongoing signal processing and reorganizes frequency map according to auditory experience in the central nucleus of bat inferior colliculus. However, whether all corticofugally affected collicular neurons are involved in both types of modulation has not been determined. In this study, we demonstrate that one group (51%) of collicular neurons participates only in corticofugal modulation of ongoing signal processing, while a second group (49%) of collicular neurons participates in both modulation of ongoing signal processing and in reorganization of the auditory system.
