[An aversive olfactory signal during the Y-maze learning of mice selected for greater or lesser brain weight].
Learning abilities of mice selected by the small and large brain weights were studied in Y-maze. Thirsty mice were trained to find water in one of the maze arms. The minimal latency of this reaction reached in the process of learning was shorter in the mice selected by the heavy brain. Benzaldehyde which is commonly supposed to be an aversive olfactory stimulus being presented before drinking sharply increased the latency, nevertheless, it remained shorter in mice with heavy brain. The response to the aversive stimulus varied between the individuals, especially in mice selected by the small brain weight.
