Unilateral intracranial injection into the left intermediate and medial hyperstriatum ventrale of 100 mumol.liter-1 7-chlorokynurenate, a highly selective antagonist of the glycine site on the N-methyl-D-aspartate receptor, prevents acquisition of memory for one-trial passive avoidance training in
Passive avoidance training has been shown to cause an increase in synaptic density (Nvsyn) in the lobus parolfactorius (LPO) of the one-day old chick. The present study was conducted to investigate the time-course over which this plastic change takes place. Two groups of chicks were trained to peck
Day-old chicks (Gallus domesticus) were trained on a one-trial passive avoidance task where the aversive stimulus was an unpleasant tasting substance, methyl anthranilate. Chicks were killed 6.5 h after training. The kinetic parameters of [3H] alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid
Injection of drugs directly into the intermediate medial hyperstriatum ventrale (IMHV) of day-old chicks, prior to training on a chrome bead dipped in either the strong aversant methyl anthranilate (MeA), or the weak aversant quinine, allows investigation of the effects of potential amnestic and
