Document Summary

Psyc 2275 - lecture 1 - introduction to brain and behaviour. Dualism: theory that the mind and the body are separate entities: descartes believed that the mind/soul was non-material, while the body was material. Materialism: theory that workings of the mind are physical properties: created by charles darwin. Biological psychology: behaviours, thoughts, and emotions, biological psychology experiments connect biology to behaviour. Three approaches: somatic intervention: the physical affects our behaviour, behavioural intervention: our behaviour affects the physical, correlation: variables cannot be manipulated. The brain controls behaviour, and behaviour modifies the brain: the concept of neuroplasticity. Glial cells: these special type of cells outnumber neurons by a ratio of 10:1, there are four types. Microglia (remove cellular debris from dead or injured cells) Oligodendrocytes (form myelin in the central nervous system) Schwann cells (form myelin in the peripheral nervous system) Directions in the nervous system: dorsal (top, anterior (front, posterior (back, ventral (bottom) Cross-section terminology: horizontal, sagittal, coronal planes.
