Document Summary

Localization of function: different parts of brain responsible for different but overlapping tasks. Lateralization: right and left sides of the brain are partly specialized. Connects sensory receptors and skeletal muscles to the cns (red nerve. Efferent nerve bers: transmit information from cns to the periphery (brain -- muscles). Afferent nerve bers: transmit information from the periphery to the cns (sensory receptors -- brain). Localization of function: different parts of the brain perform different but overlapping tasks. Spinal cord: bridge between the brain and pns. Spinal re exes: automatic responses to environment that require no higher processing. Magnetic resonance imaging (mri): magnetic eld used to map the structure of the brain. Transcranial magnetic stimulation (tms): magnetic eld created to stimulate neurons and observe their effect. Positron-emission tomography (pet): records biochemical changes in the brain over time. fmri: records activity in the brain over time. Cerebellum ne tunes motor movement; learning repeated motor movement;
