Memory channels in the rat: Effect of post-training application of potassium chloride on the hippocampus

摘要: Rats were trained to perform shuttle responses a buzzer either in Pavlovian paradigm (50 buzzer-shock pairings every 10–40 sec) or an avoidance situation without stimulus pairing buzzers sec, each followed by footshock at randomly variable 5- 35-sec interval unless the animals shuttled buzzer). Seven days later, tested same which they had been trained, other one. There was good evidence for retention all groups, involving both “direct” (Pavlovian-to-Pavlovian, avoidance-to-avoidance) and “transfer” memory (Pavlovian-to-avoidance, avoidance-to-Pavlovian). The two “transfers” appeared enhanced who received application of potassium chloride dorsal hippocampus immediately after training. Control groups intact rats with bilateral hippocampal cannulas. data support concept, advanced previous paper, separate parallel channels rat brain.
