Effects of Post-Training Blockade of GABAB Receptor on Memory of Food Location and Expression of Synapsin I in the Hippocampus of Pigeons (Columba livia) ()
ABSTRACT
This study
investigated effects of post-training treatment with phaclofen, GABAB receptor antagonist, on the memory of food location and on the
expression of Synapsin I in the hippocampus of pigeons. Pigeons were trained in
food location (7 sessions) and underwent post-training treatment with phaclofen
(0.3 mg/kg, i.p.; PHAC), saline (SAL) or non-treated (NTR). Testing for memory
persistence occurred 7 days after the last training session (PHACR, SALR and
NTRR Groups). Pigeons treated with phaclofen had lower latency and higher
correct choice values than saline and non-treated controls (p < 0.05). Analysis of hippocampus
tissue indicated that Synapsin I-positive cell counts were higher in pigeons
treated with phaclofen than in saline and non-treated controls (p <
0.05). Data indicated enhancement of consolidation and persistence of food
location memory, and up-regulation of Synapsin I expression in the hippocampus
of pigeons, which were related with post-training blockade of GABAB receptors.
