[Demonstration of an effect of (3H)-L-proline on the number of dendritic spines on stellate cells of the primary visual cortex in Macaca during the critical period].
A morphometric study in cortical layer IVC of Macaca area 17 was performed during the critical period. A 20% increase in the number of dendritic spines was observed in neurons with horizontal dendritic tree in the cortical sublayer IVC alpha after an intraocular injection of (3H)-L-proline. A neuroactive role of this amino acid is discussed.
