the parts and functions of the brain

Brainstem

responsible for automatic survival functions; made of the hypothalamus, pons, thalamus, medulla, reticular formation, cerebellum

Reticular Formation

a nerve network that plays a role in controlling arousal

Thalamus

sensory switchboard

Hypothalamus

AKA rewards center...maintenance activities: eating, drinking, body and temperature;
it governs the endocrine system via the pituitary gland and is linked to emotion

Medulla

heartbeat and breathing

Cerebellum

voluntary movement and balance

Limbic System

associated with emotions and drives

Hippocampus

part of the limbic system; involved in memory

amygdala

part of the limbic system; linked to emotion, especially fear and anger

Cerebral cortex

ultimate control & information processing center; it is what distinguishes us from animals

Glial cells

support, nourish & protect neurons; make up the cerebral cortex

Association Areas

parts of the cerebral cortex not involved in primary motor or sensory functions; involved in higher mental functions such as learning, remembering, thinking & speaking

Temporal Lobe

auditory areas

Parietal Lobe

includes sensory cortex

Occipital Lobe

visual areas, receives visual information from the opposite fields

Frontal lobe

speaking, muscle movements, plans & judgements

Motor Cortex

controls voluntary movements at the back of the frontal lobe

Sensory Cortex

registers and processes body sensation

Broca's Area

in the frontal lobe, in the left hemisphere; directs muscle movements involved in speech

Wernicke's area

In the left temporal lobe; involved in language comprehension and expression

Angular Gyrus

ability to read, controls word transformations into auditory code

Pons

contains centers for the control of vital processes, including respiration and cardiovascular functions. It also is involved in the coordination of eye movements and balance.
