Abstract:
:The functions of the fields of the mammalian auditory cortex in sound perception and recognition are unknown. We used Fos (a protein of the inducible immediate-early gene c-fos) as a cellular marker of activated brain areas to show in the mouse (Mus domesticus) that sound is processed differentially in auditory cortical fields according to its actual significance in a behavioral context. Recognition, compared with perception of exactly the same sound, produced significantly less but well focused Fos-positive cells in a primary auditory cortical field and significantly more labeling in higher auditory and association fields. Thus, recognition means a state of distinctive spatial distribution of activity in auditory cortical fields with a predominance of activation in higher-order fields.

Since acid-soluble extracts of brain contain other proteins in the 14-32 kD range (such as histones) in addition to MBP's, the identification of the ADP-ribosylated proteins was uncertain. To determine ...
