Study Notes
Neurotransmitters and Their Impact on Behavior
- Neurotransmitters are chemicals that regulate various functions in the body and human behavior, including muscle control, mood regulation, memory, and cognitive and emotional activities.
Dopamine
- Dopamine is a key neurotransmitter that regulates cognitive, emotional, and motor processes, including motivation, pleasure, movement control, reward, attention, memory, and learning.
- Imbalances in dopamine levels have been associated with conditions such as schizophrenia and Parkinson's disease.
Serotonin
- Serotonin is involved in maintaining a stable mood, regulating appetite and sleep, and is involved in cognitive processes like memory and learning.
- Imbalances in serotonin levels have been linked to neuropsychiatric disorders such as depression, anxiety, obsessive-compulsive disorder, and sleep disorders.
Norepinephrine
- Norepinephrine is responsible for regulating alertness and attention, and prepares the body for emergency responses in stressful situations.
- Excessive norepinephrine levels have been implicated in anxiety disorders such as panic disorder and post-traumatic stress disorder.
GABA
- GABA has a calming effect on the nervous system, reducing anxiety and promoting feelings of calmness and tranquility.
- Imbalances in GABA levels have been associated with various neuropsychiatric disorders.
Acetylcholine
- Acetylcholine is the most common neurotransmitter in the body, involved in transmitting signals between neurons and muscles.
- Acetylcholine deficiency leads to Alzheimer's disease, and is involved in regulating REM sleep and muscle movement.
Endorphins
- Endorphins are neurotransmitters involved in pain regulation and feelings of well-being.
- Exercise is a common way to stimulate endorphin release, promoting feelings of well-being.
Mental Illness and Neurotransmitters
- Mental illnesses are conditions that affect mental health, cognitive function, and emotional and behavioral responses.
- Imbalances in neurotransmitter levels can contribute to the development and severity of these conditions.
Treatments
- Treatments for mental illnesses include medications such as selective serotonin reuptake inhibitors (SSRIs), antipsychotics, mood stabilizers, and anxiolytics, which work by regulating neurotransmitter levels or blocking their reuptake.
- These medications must be supervised by medical professionals.
Recreational Drugs and Neurotransmitters
- Stimulants such as cocaine and amphetamines increase dopamine, norepinephrine, and/or serotonin levels in the brain.
- These drugs can lead to addiction and dependence.
