Postsynaptic potentials from a single monopolar neuron of the ganglion opticum I of the blowfly Calliphora

Hyperpolarizing potentials were recorded from second order monopolar neurons of the ganglion opticum I of Calliphora by means of glass microcapillaries using a spotlike light source to measure the intensity of the light stimulus.

Abstract

Hyperpolarizing potentials were recorded from second order monopolar neurons of the ganglion opticum I of Calliphora by means of glass microcapillaries. The eye was stimulated with a spotlike light source. Potentials were recorded in relation to the intensity of the light stimulus. The recording site was identified by marking the cell with a dye and by localizing the tip of the electrode.
