00:00:03.000 --> 00:00:12.000
The complex functions of the brain that lead to the most involved features of our behavior are linked to the cerebral cortex.

2
00:00:12.500 --> 00:00:16.000
The cerebral cortex is the most recently evolved region of the brain.

3
00:00:16.500 --> 00:00:25.000
It is comprised of a thin sheet that overlays the forebrain, covering surface bumps on the brain as well as indentations.

4
00:00:25.500 --> 00:00:38.000
The word cortex is derived from Latin and translates to “bark of the tree”. The cerebral cortex is about 1/8” thick and is comprised of many different regions.

5
00:00:38.500 --> 00:00:45.000
One of the functions of the cortex is to receive information from our senses so that we can process information about our world.

6
00:00:45.500 --> 00:00:56.000
What we see is processed by the visual cortex in the occipital lobe, what we hear is processed by the auditory cortex in our temporal lobe,

7
00:00:56.500 --> 00:01:02.000
and sensations from our skin are processed in the somatosensory cortex in the long bump at the front part of the parietal lobe.

8
00:01:02.500 --> 00:01:10.000
Another vital function of the brain is its management of our motor skills.

9
00:01:10.500 --> 00:01:16.000
These movement tasks are performed by the motor cortex - a small bump at the back of the frontal lobe.

10
00:01:16.500 --> 00:01:25.000
The motor cortex and somatosensory cortex are right across from each other along one of the major grooves in our brain.

11
00:01:27.500 --> 00:01:32.000
The somatosensory cortex is located along the front bump of the parietal lobes.

12
00:01:32.500 --> 00:01:37.000
It registers sensations that arise form the skin and inside the body.

13
00:01:40.500 --> 00:01:47.000
The auditory cortex located in the temporal lobes. It processes information from the ear.

14
00:01:48.500 --> 00:01:55.000
The visual cortex is located in the occipital lobes. It processes information from the eye.

15
00:01:58.500 --> 00:02:05.000
The Motor cortex is located along the back bump of the frontal lobes. It is important in voluntary movement.
