PSYB65H3 Lecture Notes - Circadian Rhythm, Hindbrain, Reticular Formation
Document Summary
Pns everything else (nerves from spinal cord that run out to diff parts of body to gather information) Subdivisions of brain (very general) forebrain, midbrain, hindbrain. Hindbrain: cerebellum (sensory motor integration takes info from body and linking it to motor to control body properly), medala (basic life processes heart beat/respiration) Midbrain: reticular formation -controls sleep/wakefulness cycles or circadian rhythms. Huge component of brain: cerebral cortex or nerocortex (new cortex) Ability to store information for generations after. Allows humans to distinguish themselves from other animals. Dogfish spinal cord becomes more intelligent through evolution (more nuclei = more brain cells, more reaction in a more complicated way) forebrain associated with high intellectual functions, more evolved the species the larger the cortex. Size of a structure is directly related to the function and importance of that particular species (smell is very important to rats, part of the brain that deals with smell that part of brain is very large)
