Character and Abilities

Corpus Callosum

-nerve fibers joining the two hemispheres of the brain.

-allows information to pass between the two halves.

Cerebral Cortex

The outermost layer of brain making up the superficial aspect of the cerebrum.

Frontal lobe

-language production, emotions, decision marking/reasoning, personality, voluntary movement

Motor cortex

-controls fine motor movements

-each area of cortex controls diff parts of body
LARGER AREAS: tongue, fingers
SMALLER SUBTLE MOVMENTS: shoulders/elbows

Broca’s Area lobe

speech production

Broca’s aphasia

makes speech slow, slurred, labored, w/no comprehension problems

temporal love

-hearing

-comprehension/understanding of language

wernicke’s area

lanaguge comprehension
- LOCATED ON LEFT TEMPORAL LOBE

Wenicke’s Aphasia

lanaguge comprehension is damaged

parietal lobe

-processing sensory signals from body, touch, pressure, temperature, pain.

size represents …

sensitivity

somatosensory cortex

Main sensory receptive area for the sense of touch

-most sensitive parts of the body such as lips and hands (larger areas)

-Less sensitive parts of the body such as the back and abdomen (smaller areas)

Occipital lobe

visual processing, depth perception
Visual Cortex:  receives information from thalamus

Synapse/ Synaptic Gap

Gap between two neurons in which a neural impulse may pass

receptor

-place where NT’s bind of postsynaptic neuron

-location: dendrites

vesicles

-houses transmitters in terminal buttons
