Study Notes
Hormones and Neurotransmitters
- Hormones are chemical messengers released into the bloodstream, impacting various bodily functions.
- Neurotransmitters transmit signals between neurons by crossing the synaptic gap.
Pain Relief and Mood Enhancement
- Morphine mimics the action of endorphins, substances that elevate mood and alleviate pain.
Nervous System Branches
- The parasympathetic nervous system is responsible for calming the body after stress.
Endocrine System
- The pituitary gland plays a pivotal role in growth; abnormalities can lead to unusual height in children.
Brain Hemispheres and Functions
- The left hemisphere specializes in speech and language processing.
- Split-brain research involves studies on individuals with a severed corpus callosum, allowing insights into lateralization of brain functions.
Imaging Techniques
- Computer tomography scans utilize enhanced X-rays to create detailed brain images.
Human Brain Differences
- Association areas differentiate human brains from other mammals, indicating advanced cognitive functions.
Sensory Processing
- The thalamus functions as the brain's sensory control center, processing incoming sensory information.
Drug Effects and Withdrawal
- Heroin, when abused, leads to withdrawal symptoms characterized by physical pain due to the brain’s reduced production of endorphins.
- Alcohol is classified as a depressant, calming neural activity and slowing body functions.
Performance-Enhancing Drugs
- Amphetamines are commonly misused by athletes to enhance physical performance and endurance.
Stimulants and Their Effects
- Ecstasy is a stimulant known for causing high energy, emotional highs, dehydration, and potential damage to serotonin-producing neurons.
- Near-death experiences can create altered states of consciousness similar to LSD hallucinations.
Hallucinogen Effects
- LSD can cause symptoms such as cold sweats, convulsions, and hallucinations; it is defined as a hallucinogen that alters perception and cognition.
Genetic Influences on Substance Abuse
- Alcohol dependence shows genetic ties, as adopted individuals are more vulnerable if biological parents have a history of alcoholism.
Marijuana Effects
- Smoking marijuana typically results in relaxation, mild hallucinations, and potential memory loss.
Neurotransmitter Interactions
- LSD acts as an antagonist at synapses, blocking the actions of serotonin, a key neurotransmitter.
Alcohol and Social Behavior
- Alcohol consumption typically reduces self-consciousness rather than increasing it.
Cocaine and Methamphetamine
- Cocaine and methamphetamine both lead to intense euphoria; however, meth can sustain this effect for up to eight hours.
Drug Mechanisms
- Cocaine increases neural stimulation by blocking neurotransmitter reuptake.
Marijuana Physiological Effects
- Marijuana can cause various physiological effects including dilated blood vessels, relaxation, and altered time perception.
Sleep and Dreams
- Nightmares occur primarily during REM sleep, a crucial phase for processing dreams.
Dream Theories
- The information processing theory posits that dreaming aids in sorting and consolidating daily experiences.
Sleep Regulation
- The suprachiasmatic nucleus regulates sleep by signaling the pineal gland to increase melatonin production.
Effects of Sleep Deprivation
- Lack of sleep can lead to several health issues including weight gain, weakened immune function, and an increased risk of depression.
Circadian Rhythms
- A circadian rhythm example is the daily rise in body temperature as morning approaches, reflecting natural biological cycles.
