Dye coupling between visual cortical (area 17) neurones of adult rat--A study on brain slices

Abstract

With intracellular injection of biocytin, forty-nine neurones were successfully labeled in vitro visual cortex (area 17) slices of the adult rat. Out of the sample dye coupling was found in 21 cases, for each injection the number of the coupled cells varying from 2 to 5 (mean 2.8±1.1). We have measured membrane potential and response properties to white matter and intracellular stimulation for the coupled and non-coupled cells; no significant difference was found between them.
