Brain organ that weighs 3 pounds
● Gray matter areas of the CNS with high concentrations of cell bodies; outer surface of
cerebrum (cerebral cortex)
● White matter areas of the CNS with mostly myelinated axons; inner part of the cerebrum
● Glial cellscells in the brain that nourish and protect neurons
Brain Stem hind brain
● Medulla where spinal cord meets the skull; controls heartbeat and breathing (involuntary
actions)
● Pons above the medulla that also controls involuntary actions
● Reticular formation bundle of nerves that runs through the brainstem; controls arousal,
modulates pain, filters irrelevant background information from the senses
● Thalamus pair of eggshaped organs above the brainstem; receives information from the
senses (EXCEPT FOR SMELL) and relays it to the rest of the brain
● Cerebellum in the rear of the head, behind the brainstem; controls balance and
coordination
Mid Brain Limbic System
● Amygdala two almond shaped structures; influences fear and agression (also in monkeys
and cats)
● Hypothalamus below the thalamus; regulates hunger, thirst, body temperatre, sex, fight
or flight, triggers the pituitary gland reward center
● Hippocampus behind the amygdala; memory
Fore brain Frontal Lobes Cortex
● Prefrontal Lobe very front; judgement and rationality; doesn’t fully develop until the age
of 24
● Frontal Lobe located in the forehead region
...
Also includes Broca’s area (needed for forming words; located in the left
hemisphere only) Broca’s aphasia
...
● Association areas judgement, planning , processing new memories
● Motor Cortex left heminsphere controls the right side of the body
● Sensory Cortex left hemisphere controls right side of body
● Occipital Lobe located in the back of the head; contains the visual cortex
● Temporal Lobe located on the sides of the head
...
Includes Wernicke’s areas (left hemisphere only)
part of the brain invloved in understanding language: Wernicke’s aphasia
● Corpus Callosum bundle of nerves that connects the left and right hemisphere
