Methylazoxymethanol (MAM)-induced microencephalic aged animals with reduced cortical mass and unmodified basal nucleus were used to study the relationship between cells that produce and cells that utilize NGF. Total cortical ChAT activity of MAM 2, 19 and 27 month old animals was reduced compared to their age-matched controls. To verify whether the(More)
The expression of the alpha 4 and beta 2 subunits of neuronal nicotinic acetylcholine receptors (nAChRs) was studied in developing rat brain using in situ hybridization. The levels of both transcripts were already high at birth in cerebral cortex, medial habenula, CA1/CA3 regions of the hippocampus and several thalamic nuclei. In general, the beta 2 subunit(More)
