Effect of posttraining injections of glucose on acquisition of two appetitive learning tasks

摘要: The present experiments were designed to examine the effect of posttraining glucose injections on acquisition two appetitive tasks in an 8-arm radial maze. On a win-stay visual discrimination task, presence food four randomly selected maze arms was signaled by light cue, and rats required visit each lit twice within trial. animals given one trial per day injected immediately Day 5. A dose 2.0 g/kg significantly improved relative performance controls, but 100 mg/kg had no effect. win-shift allowed obtain from arms, followed delay period which they removed returned for retention test, only that not been visited prior contained food. After training shorter delays, 18 h imposed between first second choices; after choices. Glucose doses both retention, controls. results demonstrate memory-improving action generalizes tasks, suggest can improve memory with different mnemonic requirements.
