Cerebral Cortex

• most visible and iconic part of the brain

• big wrinkly thing

• can think of it as a thin sheet of neurons crumbled up to fit in your head

• the ridges from the wrinkles are called gyri and the grooves between them are called sucli

left hemisphere:

• perceives sensory stimulation and controls movement for the right side of your body

right hemisphere:

• receives sensory info from and controls left side of body

The two hemispheres don’t work independently, they actually pass info though each other with a massive bundle of neurons calls the corpus callosum

Frontal Lobe:

• in front of the cerebral cortex

• decision making

• physical and mental

Parietal Lobe:

• above and in front of the occipital lobe

• processes information about touch

Occipital Lobe:

• back of the cerebral cortex

• processes visual info

Temporal Lobe:

• lower side of each hemisphere

• hearing and language

• helps us understand word and sentences
