Effects of Micro-injections of L-Glutamate into the Hypothalamus on Attack and Flight Behaviour in Cats

WE have carried out experiments in which cannulae (26 gauge, insulated except for 0.25 mm at their tips) were implanted stereotaxically in six adult cats in regions of the hypothalamus that produce “direct attack behaviour”, “flight behaviour” or a combination of both of these behaviours with electr...

Description
Summary:WE have carried out experiments in which cannulae (26 gauge, insulated except for 0.25 mm at their tips) were implanted stereotaxically in six adult cats in regions of the hypothalamus that produce “direct attack behaviour”, “flight behaviour” or a combination of both of these behaviours with electrical stimulation 1 . Electrical thresholds for “attack” and “flight” were determined with a constant-current stimulator, and 1 M L-glutamate, p H 7.4, was injected with a microlitre syringe. Adult unanaesthetized rats were used as attack objects 1 .
