Q

“How neurons communicate”
- The language of neurons
- Triggered when the electric charge within a neuron reaches a high enough level relative to the outside causing the neuron to “fire”
- All or nothing
- Triggers a release of neurotransmitters into the synapse

A

Q

Excitatory (rapidly excites neuron), stimulates, enhanced learning and memory, most prevalent neurotransmitter. Can be a contributor of schizophrenia because it overexcites neurons causing hallucinations. Other disorders is Epilepsy
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide

Q

Most powerful Inhibitory (derived from glutamate), anti-anxiety, learning, memory and sleep. Acts as a brake for glutamate. Dampens glutamate. When Gamma is abnormally low, it can cause anxiety. For example, anti anxiety drugs replicate the function of Gamma.
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide

Q

Excitatory neurotransmitter arousal, selective attention, sleep, memory. Motor neurons, excite muscle cells. Muscle contraction, but it can also inhibit the cardiac region. Some poisons cause paralysis by blocking the acetylcholine receptors. Example is Alzheimer’s Disease.
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine

Q

Reward and pleasure. Effects are both excitatory and inhibitory. Also involved in motor function. Plays a role in addiction. Brain areas rich in dopamine become active when we do pleasurable activities. Dopamine deficiency can cause parkinson’s disese. Too much dopamine can lead to confusion and loss of focus. Dopamine is involved in motivation.

16
Q

Excitatory neurotransmitter. Brain arousal and other functions. Produced by brain stem, hypothalamus and amgadjkdfkj glands. Implicated by mood. Low causes anxiety and depression. Too high can cause. Some drugs like meth can increase Norepinephrine. Ritalin reduces focus (ADHD Drug)
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide

A

Norepinephrine

17
Q

Mood and temperature regulation. Well-being and happiness. Mood neurotransmitter. Secreted by neurons of the brain stem. (Lowness) Associated with depression, OCD, suicidal ideations. Body temperature and perception of pain. Inhibitory neurotransmitter. Selective Serotonin Reuptake Inhibitor; medicine for depression.
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide

A

Serotonin

18
Q

Neuropeptides; short strings of Amino Acids (building blocks of proteins). Pain reduction. Morphine and other opioids produce more endorphins by hijacking the endorphin receptors.
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide

A

Endorphins

19
Q

Eating, motivation, memory, sleep, pain reduction. Marijuana produces similar effects as Anandamide..
- Glutamate
- Gamma-Aminobutyric Acid
- Acetylochloline
- Dopamine
- Norepinephrine
- Serotonin
- Endorphins
- Anandamide
