What is the cerebral cortex?

2. Unit 3B : The Brain
The Cerebral Cortex

3. Intro Cerebrum 2 large hemispheres on the brain Cerebral Cortex
layer of neural networks that cover the cerebrum
The spider web over brain used for the spiders to communicate

4. Structure of Cortex Glial Cells (glue cells) Lobes Frontal Parietal
speaking, muscle movement, judgement
EX: saying words
Parietal
sensory input for touch & body position
EX: feeling a tickle
Occipital
receiving info for vision
EX: seeing teacher
Temporal
receive info for hearing (opposite ear)
EX: hearing lecture

5. Function of the Cortex - Motor
Motor Cortex
Involved in voluntary movement
located in the back of the frontal lobe
controls movement for opposite side of body
EX: left part of brain controls kicking ball with right foot
Mapping & Neural Prosthetics
Mapping of the motor cortex has opened the door for improved prosthetics which are artificial limbs

6. Function of the Cortex - Sensory
Sensory Cortex
Located at the front of the parietal lobe
responsible for processing touch and movement sensations
Left hemisphere takes info from right side of body
EX: processing of hand being held

8. Functions of the Cortex – Association Areas
These areas link sensory inputs with stored memories
association areas are found on all 4 lobes
Frontal Lobes
judging, planning, &processing new memories, recent studies have shown that moral compass can be here as well
damage means you can still think but planning and inhibitions gone
Parietal Lobes
allow math and spatial reasoning
Temporal Lobes
lobe allows facial recognition
damage would mean you can describe the face but can’t recognize it

9. Language Aphasia Broca’s Area Wernicke’s Area Unable to use language
EX: concussion and now cant speak or understand others speaking
Broca’s Area
Controls muscles needed to speak
EX: moving lips to make words
Wernicke’s Area
Meaning of words
EX: describe what’s going on in the picture… understanding

11. The Brain’s Plasticity
Brain Damage
Plasticity
Being able to modify itself after damage
EX: constraint-induced therapy
Constraint- induced therapy
Reprogram brain to use damaged areas
Neurogenesis
Formation of new neurons
Think stem cells
