BIOLOGY 25 Lecture Notes - Lecture 5: White Matter, Motor Cortex, Brainstem
Document Summary
Anatomy behind cognitive control: prefrontal cortex: > most ventral part= orbitofrontal cortex= ventromedial zone. 2 control systems: lpfc and fp, supports goal orientated behaviour. Works with more posterior regions to constitute a working memory system, that recruits and selects task-relevant information: mfc, works with pfc, guides and monitors behaviour. Modulates degree of cognitive control needed to keep behaviour in line w. goals. Humans and animals: human pfc has more white matter, pfc matures late. Hammer, nail: utilization behaviour (automaticly does it, extreme dependency on prototypical responses for guiding behaviour) Goal orientated behaviour: 2 types of actions: A) goal-orientated actions: based on reward, knowledge of causal relationship betw. B) habits: automatic, no longer under control of reward, but stimulus driven. 1. 2 science: dissociating the role of the dlpfc and acc (macdonald) Implementing control, maintenance and manipulation of information of working memory, strategic processing. In preparatory phase: when task is to name colours, compared to words.
