Electrotonic synapses İn young rat İnferİor colliculus

Abstract

Biocytın was injecıed into neurons in frontal sliees of inferİor eollicııliıs (IC) from raıs. Eıghtecn oııt of 76
intraeellular injection of bioeytin inlü single neurons resulted in staining of more than one cel i (23%). Longer bioeytı n ınjectıon
times resulted in a higher incidenee and increased numher of coupled eclis. One minute of hıoeytin inJection resulted ın 16v

ıncıdence raıe of eoupling. whereas 5- i(J minute of injeetion resulled ın 28%. There was no diff'ercnee ın ıhe incidcnee of dye
coııpling when the sliee was ineubated in the bath for long or short period ., after the bioeytın injection. I-Iowcver. ıhe dye coııpling
was eorrelated with the age of aniıııal; ıhe ineidenee rate of the eouplıng among stained cells was 2X"!r: ııı ıe slıce preparaııon, froııı
