Document Summary

Neural plasticity: during learning, long-term potentiation occurs and makes synapses perform better. Brain-behaviour network: sensory information comes into-and decision come out of - the central nervous system (cns, the nerves outside the cns are called the peripheral nervous system (pns) Parietal lobe: specialized for touch and perception, somatosensory cortex is sensitive to pressure, pain and temperature, passes information to the motor cortex every time we reach, grasp. Occipital lobe: specialized for vision, located in the back of the brain. Temporal lobe: lower part of the cerebral cortex, it plays a role in hearing, understanding language, and storing autobiographical memories, co(cid:374)tai(cid:374)s the auditor(cid:455) (cid:272)orte(cid:454) a(cid:374)d wer(cid:374)i(cid:272)ke"s area, respo(cid:374)si(cid:271)le for spee(cid:272)h comprehension. Cortical hierarchies: when sensory information enters the brai(cid:374), it irst goes to that se(cid:374)se"s pri(cid:373)ar(cid:455) se(cid:374)sor(cid:455) cortex, then to the association cortex, called hierarchical because processing becomes increasingly. Left hemisphere: fine tuned language skills, speech comprehension, speech production, phonology, syntax, reading, writing, actions, making facial expressions, motor detection.
