Document Summary

Aphasia loss of ability to speak: broca"s aphasia. Difficulty producing language rather than understanding: wernicke"s aphasia. Deficit in speech comprehension without the loss of speech production. Damage to left side (closer to back of brain) 2 halves left and right hemispheres (control behaviour: right 3d space/special relationships, left speech. Connected by nerve fibres (axons) including the corpus callosum (bridge) Consciousness, sleep, life maintaining functions (breathing, heartbeat, and blood pressure) If damaged paralysis, coma, death (b/c it controls the basic life functions: cerebellum. Pair of hemispheres involved in motor control. Movements are coordinated, well timed, and precise. If damaged movements are clumsy, loss of balance, difficulty judging sensory timing: hypothalamus. Hormonal systems, drives hunger and thirst, body temp. Sensory info/motor signals from basal ganglia and received and sent to cerebral cortex. Regulating wakefulness and sleep: basal ganglia. Subcortical structures that exchange info between part of the cerebral cortex. Voluntary movement, memory (remembering how to do something: limbic system.
