Abstract

Exposure to insulin increased stimulus-evoked transmission at synapses formed in culture by cholinergic retinal neurons derived from fetal rats. This effect occurred at physiological concentrations and was long lasting. The findings support the hypothesis that insulin may serve as a developmental signal to regulate the emergence of effective neurotransmission across nascent synapses.
