In keeping with the diversity of these behavioral affiliations, cholinergic pathways reach all levels of the neuraxis but also display a strict topographical arrangement. Modern methods for axonal tracing and immunohistochemistry have led to the accumulation of considerable information

Although anatomically confusing, this distribution is understandable if it is realized that all of the groups are situated within and along the major fiber pathways of the ventral forebrain. Thus, the nuclei of the diagonal band and the medi

Why is the brain not hard-wired exclusively for the information processing mode, as seen in computers? What is the biological significance of

Die Registrierung der Exoelektronen,m began in the mid-1970s when a population of neurons in the basal forebrain was discovered to project to cerebral cortex (Divac, 1975; Kievit and Kuypers, 1975). It was later established that the neurotransmitter for the cortically projecting neurons was acetylcholine (ACh) (Mesulam et al., 1983; R
