1
New cards
Brainstem
- the oldest part of the brain - beginning where the spinal cord swells and enters the skull (responsible for the automatic survival functions)
2
New cards
Medulla
- the base of the brainstem that controls heartbeat and breathing
3
New cards
Reticular Formation
- a nerve network in the brainstem that plays an improtant role in controlling arousing
4
New cards
Pons
- helps with movement and facial expression
5
New cards
Cerebellum
- the "little brain" attached to the rear of the brainstem - helps coordinate voluntary movements and balance
6
New cards
Thalamus
- the brain's sensory switchboard located on top of the brainstem consolidates sensory input into a cohesive feeling
7
New cards
Hypothalamus
- lies below the thalamus - regulates circadian rhythm and food intake - the brains link to the pituitary gland
8
New cards
Hippocampus
- processes memories
9
New cards
Amygdala
- consists of two almond shaped-neural clusters linked to the emotions of fear and anger
10
New cards
Cerebral cortex
- the intricate fabric of interconnected neural cells that covers the cerebral hemispeheres - the bodys ultimate control and information processing center
11
New cards
Frontal lobe
- judgemental/reasoning - dopamine highway
12
New cards
Parietal lobe
- senses
13
New cards
Occipital lobe
- vision
14
New cards
Temporal lobe
- hearing
15
New cards
Motor cortex
- the area at the rear of the frontal lobes that control voluntary movements
16
New cards
Sensory cortex
- the area at the front of the parietal lobes that recieves info from skin surface and sense organs
17
New cards
Outout motor cortex
- left hemispheres section controls the body's right side
18
New cards
Input motor cortex
- left hemisphere section recieves input from the body's right side
19
New cards
Visual cortex
- located in the ocipital lobe of the brain
20
New cards
Auditory cortex
- located in the temporal lobe of the brain
21
New cards
Specialization & Integration
- brain activity when hearin, seeing, and speaking works
22
New cards
Association areas
- integrate sensory info and stored memories
23
New cards
Left hemisphere
- processes logical tasks ex.) reading, writing, speaking, math - controls the right side of our body
24
New cards
Right hemisphere
- processes non-verbal tasks ex.) mental imagery, musical/artistic ability - controls the left side of the body
25
New cards
Corpus collosum
- wide band of axon fibers that connect the two hemispheres and allow them to communicate
