PSYCH 1 Lecture Notes - Lecture 28: Neuroplasticity, René Descartes, Materialism
Document Summary
Brain areas are densely connected integrated brain functioning. Function of brain is determined by its connectivity, properties of neurons in that area, and by types of neurotransmitter receptor the area has. Two sides of brain (relatively symmetrical) differ in both structure and function. Language is dependent more so on left hemisphere lateralized to the left. Motor & sensory functions are crossed (right motor cortex controls left side of. Several local centres work together in parallel to support complex body; vice versa) functions. Lateralization of function: left and ride hemispheres of brain are specialized for different functions. Short acting sedative is administered to one hemisphere putting it to sleep for 5-10min. Determined that speech (verbal) is lateralized in left hemisphere. Prefrontal cortex develops until 25 (involved in logic and complex thinking) Damage to frontal lobe and limbic system changes to emotional. Repeated pattern of neurons firing strengthens synapses forming new neural circuit (cell response and personality assembly)
