Lobes

Temporal Lobe

Processes auditory information

Involved in memory

Parietal Lobes

Process touch sensation (general somatic)

Also has "sensory integration" areas

Sensory Integration Areas

Coordinate information from various senses

Occipital Lobes

Process visual information

Primary Sensory Areas

Areas within the lobes where sensation is first consciously detected

IE: temporal=sound, parietal=touch

-recognition of sensation without identification

3 Major Gyri

1. Superior

2. Medial

3. Inferior

ALL located in Temoral Bone

Heschl's Area

- Primary sensation of sound

- Deep within temporal lobe, near the insula, at the posterior end of the Sylvian fissure

- found on BOTH left and right temporal lobes

- LOCATED: interior of the superior temporal gyrus

Wernicke's Area

On the superior temporal gyrus, at the posterior end of the Sylvian fissure

Function: processes speech sounds

ONLY found on the LEFT hemisphere of the Temporal Bone
