NROC61H3 Lecture Notes - Lecture 5: Prefrontal Cortex, Long-Term Memory, Neural Pathway
Document Summary
1. learning and memory systems: early studies, neural circuitry of action and habit. 2. relevance to addiction: neurochemical and neural evidence for aberrant control over behavior learning and memory systems. 1. there are many neural systems that mediate different types of associative learning mechanisms. 2. these operate in parallel but also associate with one another organization of learning and memory systems. 1. single food pellet placed at the end of each arm. 3. collect all rewards without reentering the arm again. 4. for successful performance must use spatial cues (hippocampal learning: hippocampal dependent task. 5. results a. fornix lesion a. i. most amount of errors: dorsal striatum lesion c. lateral amygdala lesion c. i. least amount of errors than control task win-stay. 1. light stimulus that signals availability of reward (in 4 of 8 arms) 2. collects 8 pellets by entering each lit arm twice. 3. successful performance stimulus response learning task (dorsal striatum)
