PSYC 106 Lecture Notes - Lecture 19: Sense, Neuroanatomy, Basal Ganglia
Document Summary
Today"s material: body and brain interaction- interoception and the microbiota-gut-brain axis. Interoception- ability to sense physiological conditions in body: especially viscera, pain, temperature, itch, and other types of touch sensation, can be thought of as a sixth sense, is distinct from proprioception, distinct but somewhat overlaps touch perception. Exteroception- awareness of outside conditions (vision, hearing, etc) Function of interoception- maintaining homeostasis and guiding behavior based on physiological signals: supports eating, drinking, sexual behavior, etc, monitors metabolic and immune processes in tissue, is normally unconscious, but we can be made conscious of conditions. Both go through spinal cord, brainstem nuclei, to thalamus to insula. Insula- located in temporal cortex, very deep (covered by other cortical areas); near subcortical areas. Interoceptive awareness- subjective perception/interpretation of physiological signals: use rating scales like the multidimensional assessment of interoceptive. Tests noticing, body trusting, emotional awareness, self-regulation, etc.
