 Basal forebrain cholinergic neurons are thought to play an indispensable role in the functional neuronal pathways of learning and memory. Some correlations between death of these neurons and senile dementia of the Alzheimer type have been pointed out. NGF, one of the well-characteized neurotrophic factors, has been known to play an important role in neuronal differentiation and cell survival of basal forebrain cholinergic neurons.

 In the present communication, we will demonstrate the establishment of primary neuronal cell culture technique from the postnatal rat CNS to study the NGF response to the cholinergic neurons. We have appeared that, during the early postnatal day, the action of NGF changes from the induction of choline acetyltransferase activity to the promotion of cholinergic neuronal cell survival in septal cholinergic neurons in culture. NGF appeared to support cell survival of basal forebrain cholinergic neurons obtained from P11-P15 rat septum, the vertical limb of the diagonal band of Broca and the nucleus basalis of Meynert. The role of NGF appeared to change from a differentiation factor to a survival-promoting factor during the early postnatal period, which is just coincident with the period of completion cf the septal projection to the hippocampal formation.
