PSYCH 2GG3 Lecture Notes - Lecture 5: Putamen, Caudate Nucleus, Globus Pallidus
Document Summary
Through the lateral nucleus, the amygdala receives information from the outside world. The primary function of the basal nucleus is stimulating fear response: what we see is emotionally relevant info being encoded by the lateral nucleus and then it gets pushed forward by the basal nucleus. The fear system is intended to avoid pain or injury. Two major pathways between the sensory association cortex and the motor association cortex: direct transcortical connections (connections from one area of the cerebral cortex to another, connections via the basal ganglia and thalamus. Important for movement and habit formation (repeated behavior we start to do instinctively) We need to have help from somatosensory inputs for the brain. Certain parts of the forebrain are really important: primarily sensory and motor areas: for them to get connected in a habitual way, the basal ganglia is the most important thing.
