|
Visual areas.
|
|
|
What does acetylcholine do?
|
When released to muscle cell, it contracts. In the junction of all motor neuron leading to skeletal muscle cells.
Enables muscle contraction, learning, and memory. |
|
|
What happens when there is a lack of ACH?
|
Paralyzed.
ie: Botulin Or loss of memory ie: Alzheimers |
|
|
What happens when there's too much ACH?
|
The body goes into spasms, convulses, and eventually leads to death.
ie: Black widow bite |
|
|
What does dopamine do?
|
Influences movement, emotion, learning, and attention.
Also is the 'reward' neurotransmitter. |
|
|
What happens if you were lacking in dopamine?
|
The brain would produce tremors and the person would have decreased mobility
ie: Parkinsons |
|
|
What happens if there's too much dopamine?
|
Can become schizophrenic
|
|
|
How does cocaine and nicotine relate to dopamine?
|
They both cause the body to release an excess of dopamine which causes the user to temporarily feel good about themselves.

What does norepinephrine do?
|
Helps control alertness and arousal
|
|
|
How is cocaine and amphetemines linked to norepinephrine?
|
They release a shit ton of it.
|
|
|
What happens when there is an undersupply of norepinephrine?
|
It can lead to depression.
|
|
|
What does GABA do?
|
It helps keep the CNS at a normal level.

Pert and Snyder
|
|
|
What do endorphins do?
|
They are natural opiates in the body that are released after painful and vigorous exercise. They lessen pain and boost mood.
|
|
|
What are the three secitons of the brain?
|
Forebrain, midbrain, hindbrain
|
|
|
What is in the forebrain?
|
The anterior and largest part of the brain, it includes the cerebal hemispheres, limbic system, thalamus and hypothalamus, and the corpus callosum.
|
|
|
What does the forebrain do?
|
It controls cognitive, sensory and motor function, regulate temperature, reproductive functions, eating, sleeping, and display of emotions. Essentially, our personality!
|
|
|
What is the prefrontal cortex in charge of?
|
thinking, motivation, planning the future, impulse control, emotional responses, regulates experiences (alcohol causes you to lose impulse control and slows things down in general)
|
|
|
How do we know so much about the prefrontal cortex?
|
Prefrontal lobotomies and Phineas Gage.
|
|
|
What is the hindbrain comprised of?
|
Comprises of the pons, medulla, and cerebellum
|
|
|
What does the hindbrain do?
|
Coordinates motor activity, posture, equilibrium, and sleep patterns and regulate unconscious but essential functions like breathing and blood circulation
|
|
|
What does the midbrain do?
|
Controls functions like visual and auditory systems like eye movement. Involved in body movement.
|
|
|
What are the major brain divisions?
|
Cerebrum, diencephalon, cerebellum, brain stem
|
|
|
What is the forebrain consists of in term of brain organs?
|
Hippocampus, hypothalamus, limbic system, cerebral cortex
|
|
|
What does the hippocampus do?
|
Processes
|
|
|
What does the amygdala do?
|
Control fear and aggression
|
|
|
What does the hypothalamus do?
|
Hunger, thirst, body temperature, and sexual behavior, monitors blood chemistry, takes controls from other parts of the brain and also triggers release of dopamine associated with sex, eating, and drinking.
|
|
|
Who discovered the hypothalamus' function?
|
Olds and Millner with rats
|
|
|
What does the cerebral cortex do?
|
It is the ultimate control and information process center.
|
|
|
What are the parts of the cerebral cortex?
|
Frontal, occipital, parietal, temporal
|
|
|
What does the parietal cerebral cortex do?
|
Sensory input for touch and perception.
|
|
|
What does the occipital cortex do?
|
Visual areas
|
|
|
What does the temporal cortex do?
|
Auditory areas
