The small magnocellular group located within the rostrolateral extension of the basal forebrain was named and described as the nucleus subputaminalis in the human and chimpanzee brain by Ayala. Analysis of cytoarchitectonic and cytochemical chracteristics of this cell group has been largely disregarded in both classical and more current studies. We examined the nucleus subputaminalis in 33 neurologically normal subjects (ranging from 15 weeks of gestation to 71 years-of-age) by using Nisll staining, choline acetyltransferase immunohistochemistry, acetyl cholineesterase histochemistry and nerve growth factor receptor immunocytochemistry. In addition, we applied reduced nicotinamide edenine dinucleotide phosphate-diaphorase histochemistry and calbidin-D28k immunocytochemistry in three neurologically normal subjects. At the most rostrolateral levels we described the previously poorly characterized component ot he lateral(periputaminal) subdivision of the subputaminal nucleus, which may be human specific since it is not described in non-human primates. Moreover, we find the human subputaminal nucleus best developed at the anterointermediate level, which is the part of the basal nucleus that is usually much smaller or missing in monkeys. The location of subputaminal cholinergic neurons within the frontal lobe, the ascension of their fibers through the external capsule towards the inferior frontal gyrus, the larger size of the subputaminal nucleus on the left side at the most rostral and anterointermediate levels and the most protracted development among all magnocellular aggregations within the basal forebrain strongly suggest that they may be connected with the cortical speech area. These findings give rise to many hypothesis about possible role of the subputaminal nucleus in various neurodegenerative, neurological and psychiatric disorders, particulary Alzheimer's disease and primary progressive aphasia. Therefore, future studies on the basal forebrain should more carefully investigate this part of the basal nucleus.
