- Brainstem
- - the oldest part of the brain. RESPONSIBLE FOR AUTOMATIC SURVIVAL FUNTIONS
- Medulla
- the base of the brainstem. CONTROLS HEARTBEAT AND BREATHING
- Reticular formation
- plays an important role in controlling arousal
- Thalamus
- directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.
- Cerebellum
- the little brain attached to the rear of the brainstem. HELPS COORDINATE VOLUNTARY MOVEMENT AND BALANCE
- Limbic system
-
Associated with emotions such as fear and aggression and drives such as those for food and sex.
hippocampus, amgydala, and hypothalamus - Amygdala
- components of the limbic system and are linked to emotion
- Hypothalamus
- Directs several maintanence activities (eating, drinking, body temp), helps govern the endocrine system via the pituitary gland, and is linked to emotion
- Cerebral cortex
- The body’s ultimate control and info-processing center.
- Glial cells
- support, nourish and protect neurons.
- frontal lobes
- just behind the forehead. INVOLVED IN SPEAKING, MUSCLE MOVEMENTS, AND MAKING PLANS AND JUDGEMENTS.
- parietal
- of the head and toward the rear. Includes the sensory cortex
- Occipital
- back of the head. Includes the visual areas, which receive visual info from the opposite visual field.
- temperal lobes
- auditory areas, each of which receives auditory info primarily from the opposite ear.
- motor cortex
- controls voluntary movements
- Sensory cortex
- front of the parietal lobes that registers and processes body sensations
- association areas
- involved in higher mental functions such as learning, remembering, thinking and speaking.
- aphasia
-
- impairment of language
damage either to Broca’s area (impairing speaking) or to Wericke’s area (impairing understanding - Brocas area
-
controls language expression
directs the muscle movements involved in speech - Wernickes area
- controls language reception. A brain area involved in language comprehension and expression. Usually in the left temperal lobe.
- angular gyrus
- recevies visual info (READING ALOUD)
- plasticity
- the brains capacity for modification, as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development.
- corpus callosum
- large band of neural fibers connecting the two brain hemispheres and carrying messages between them
