Abstract:
A combination of techniques were used to sub-divide the auditory cortex of the ferret. The primary auditory cortex (AI) could be identified as an area of dense myelin, acetylcholinesterase and succinate dehydrogenase staining with high 2-deoxyglucose activity which could be reduced by ablation of the inferior colliculus and which contained three callosally labelled bands which ran in a dorsoventral direction orthogonal to the isofrequency contours. In addition, up to five secondary auditory fields were also identified: (1) A ventroposterior area (VP) which had dense myelin, acetylcholinesterase and succinate dehydrogenase staining, high 2-deoxyglucose activity which could be reduced by ablation of the inferior colliculus and was reciprocally connected to AI. (2) A ventroanterior area (VA) which had dense myelin staining, high 2-deoxyglucose activity which could be reduced by ablation of the inferior colliculus and was reciprocally connected to AI. (3) An area around the suprasylvian gyrus/suprasylvian sulcus (A) which had dense myelin and succinate dehydrogenase staining, high 2-deoxyglucose activity which may be reduced by ablation of the inferior colliculus and was reciprocally connected to AI. (4) An area on the gyrus dorsal to the suprasylvian gyrus (M) which had dense myelin staining and was reciprocally connected to AI. (5) An area ventral to VP (V) which was reciprocally connected to AI. The density of certain neurochemicals, thought to be involved in plasticity, was also studied in ferret AI during development.
