The cerebral cortex and the weird wacky brain

what is the cerebrum

Divided into two hemispheres connected to corpus callosum

The cerebral cortex is responsible for what

Higher brain functions such as perception, voluntary muscles, and thoughts

what is a Sulcus

fold or wrinkle

what is brocas aphasia

language disorder from brain damage

What are examples of specialized areas?

brocas area and prefrontal

how do specialized areas in the brain work?

They know exactly what structure of the brain is responsible for

What is an association area?

Surrounded by primary areas and interpert info

What are examples of association areas?

process and interpretation

what is olfactory bulb?

sense of smell to the olfactory, this is the only sense that does not go through the thalamus

what does the frontal lobe do?

Judgment ,planning, and motor skills

What does the prefrontal cortex do?

Planning

if you damage the prefrontal cortex, what can happen

Areas can alter judgment

what case led to doctors questioning cerebral locations?

phineas gage

What is the Broca area responsible for?

Responsible for speech alterations

where is Broca area located?

The left brain

if the Broca area is damaged, what happens?

Results in aphasia

The association area is responsible for what also

Math and spatial reasoning

in the parietal lobe, what happens

somatosensation

what is somatosensation

Touch, pain, pressure and temperature

The occipital lobe is responsible for what

Seeing and sight

The temporal lobe is located where

In the hippocampus and amygdala

what is the auditory cortex responsible for?

Hearing

wernicke area is what

where languages taught, speech comprehension

In the Wernicke area, where is it located

left side of brain

what is wernicke aphasia

Can’t make sentences, language impairment also can’t understand speech

what is Fusiform gyrus responsible for?

Facial recognition

what is prosopagnosia

facial blindness

what is the phantom limb syndrome?

person loses a limb, but can still feel the pain in touch sensation on limb that isn’t there

what is pruning?

brain gets rid of unused synapse or nerves to improve brain efficiency

how does pruning connect to the Phantom limb?

When the limb is lost the neurons die, and are pruned away

What is brain plasticity?

the brain’s ability to change or re-organize

What is the reasoning behind Phantom limb?

The neurons of the amputated limbs are pruned

What is the corpus callosum

Bundle of nerve fibers that connect the two hemispheres

What does the corpus callosum send?

neural messages between left and right hemisphere

the left in the right side of the brain can what?

function together?

what is contralaterality

opposite side of the brain controls opposite side of the body?

what is an example of contralaterabilty

left side of the brain controls right side of body?

what does the left hemisphere do?

Language, math, science and logic

what does the right side of the brain do?

Reasoning, art, music, and imagination

What is split brain surgery used for?

severe epilepsy?

What does split brain surgery do to the corpus callosum

destroys it

what is ablation or lesion

destruction in brain tissue

what are effects of split brain surgery

Patient is left with “two brains”
