Learning Performance of Normal and MutantDrosophila after Repeated Conditioning Trials with Discrete Stimuli

摘要: A new olfactory conditioning procedure is described using short training trials with discrete presentation of conditioned stimuli (CS) and unconditioned (US). odor along a single-shock stimulus produced modest but reliable reproducible learning. Multiple presented sequentially improved performance increasing trial number. Trial spacing had significant impact on performance. Two intertrial interval (ITI) no improvement over single trial; two 15 min ITI significantly boosted This effect required associative trials, because substituting one the CS alone, US or an unpaired CS–US failed to boost The increase in initial decayed within after training. Thus, short-lived. utility battery tests, including trial, massed spaced investigate parameters memory formation several mutants was demonstrated.
