Ch.3 pt2

Consists of medulla, pons, and midbrain

involving in maintaining balance, and regulating heart rate and breathing.

Involved in modulation of mortor activity

relay station of the brain, directs signals passing between the body and the brain

important for balance, coordination, and preplanned actions

reponsible for executing planned actions

regulates the internal enviroment of the body by contolling the autonomic NS. controls hormone levels, and drive states (hunger,thirst)

involved in emotion regulation and fear

important for memory, especially forming new memories, and spatial memories (giving directions)

Social Behavior

• divided into two hemisphere
• contralaterally organized: information from the right side of body is processed on the left and vice versa.

band of tissue that connects the two hemispheres and allows them to communicate.

Primary visual cortex, primary auditory cortex, somatosensory cortex

sends signals to the motor neurons, controls motion

integrate sensory information to perform complex functions

adjacent portions of cortex control adjacent body parts (dovoted more to areas with more sensitivity)

• involved in motion and higher order cognition, such as reasoning, planning, and language production
• also involved in mood and personality
• notable areas: prefrontal cortex, morotor cortex, broca's area

• important for touch sensation, perception, orbject recognition, and number representation
• notable area: Somatosensory cortex

• imporatant for auditory sensation, understanding language, and storing autobiographical memory
• notable areas; primary auditory cortex, wernicke's area

• important for vision
• notable area: primary visual cortex

• Broca's Aphasia: inablilty to produce speech
• Wernickes aphasia: inability to comprehend speech

some funtions are only processed by one hemisphere
