PSYA01H3 Lecture Notes - Lecture 9: Parietal Lobe, Frontal Lobe, Sensory Cortex
PSYA01 – Lecture 9: The Brain (pt.2)
- Parietal lobe – where our body is and spatial awareness in the world
• Association cortex →involved in complex spatial functions that differ across
hemispheres
▪ LEFT = keeps track of spatial location of our body parts (proprioception)
- damage often associated w/poor motor mvmts
▪ RIGHT = keeps track of spatial location of things in our external world
- damage lead to problems of neglect + spatial integration of parts
CONTINUED FROM LAST LECTURE…
• Primary sensory cortex →perception of the body
▪ Sensory strip: frontal cortex of the parietal lobe (pink) used to process sensory
neurons *contralateral*
▪ Brain Matter dispersed + amount allocated in different areas of the body
1. LEFT= detect input from R.side
2. RIGHT= detect input from L.side
▪ Motor Strip: more on frontal lobe; motor output
Sensory Cortex – Homunculi
(Bigger areas = more brain tissue)
