|
The cerebral cortex |
A thin surface layer of interconnected neural cells. It is your brain's thinking crown/ultimate control and info-processing center |
|
|
Glial cells |
Provide nutrients and insulating myelin, guide neural connections, and mop up ions/neurotransmitters. By "chatting" with neurons they may participate in information transmission/memory |
|
|
How is the cortex divided? |
Each hemisphere is divided into four lobes, separated by prominent fissures (folds) |
|
|
The frontal lobes |
(Behind your forehead) involved in speaking and muscle movements and in making plans and judgements |
|
|
The parietal lobes |
(At the top/to the rear) receive sensory input for touch/body position |
|
|
The occipital lobes |
(At the back of the head) include areas that receive info from the visual fields |
|
|
The temporal lobes |
(Above your ears) include the auditory areas, each receiving primarily from the other ear |
|
|
Motor cortex |
An area at the rear of the frontal lobes that controls voluntary movements |
|
|
Somatosensory cortex |
Specializes in receiving information from the skin senses/the movement of body parts. This cortex receives input from the visual cortex(occipital lobes) and the auditory cortex(temporal lobes) |
|
|
Association areas |
Involved in learning, remembering, thinking, and speaking. These areas interpret/integrate/act on sensory information and link it with memories |
|
|
The prefrontal cortex |
(Forward part of the frontal lobes) enables judgement, planning, and processing of new memories |
|
|
Plasticity |
The brain's ability to modify itself after damage |
|
|
Neurogenesis |
The process of the brain self-repairing by reorganizing existing tissues and producing new brain cells |
