Behavior Genetics
The genetic transfer of characteristics from parent to offspring.
Heredity
Receives information from the eyes
Visual cortex and/or occipital lobe
With a neuron, more stimulation does not produce a more intense neural transmission.
All-or-none response
Mild hallucinogen because it amplifies sensitivity to colors, sounds, tastes, and smells.
Marijuana
Influence the perception of pleasure and pain.
Endorphins
The proportion of variation among individuals in a group that we can attribute to genes.
Heritabilty
Receives auditory information, primarily from opposite ear.
Temporal lobe and/or auditory cortex
Drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgment such as anti-anxiety and sleep medications.
Barbiturates
Depressant that it acts as an agonist with inhibitory GABA receptors making them more inhibitory.
Alcohol
Affects mood, hunger, sleep, and arousal.
Serotonin
Every non-genetic influence, from prenatal nutrition to the people and things around us.
Environment
Just above the medulla; controls REM sleep, taste, and helps coordinate movements
Pons
A powerfully addictive drug that stimulates the central nervous system, with accelerated body functions and associated energy and mood changes.
Methamphetamine
Stimulant that reaches the brain within 7 seconds, twice as fast as intravenous heroin.
Nicotine
Influences moving, learning, attention, and emotion.
Dopamine
The study of environmental influences on gene expression that occur without a DNA change.
Epigenetics
Processes sensory input, coordinating voluntary movement and balance, nonverbal learning and memory
Cerebellum
Located in the spinal cord receive the information from the sensory neurons and send signals back through motor neurons.
Interneurons
Stimulant that binds to the sites that normally reabsorb neurotransmitter molecules, and blocks reuptake of dopamine, norepinephrine, and serotonin.
Cocaine
Enables muscle action, learning, and memory.
Acetylcholine
The complete instructions for making a human organism, consisting of all the genetic material in that human’s chromosomes.
Human Genome
Nerve network that travels through the brainstem into the thalamus; helps control consciousness, arousal, and filters incoming sensory stimuli
Reticular formation
Registers information from the skin senses and body movement
Somatosensory cortex
Amphetamine derivative that triggers dopamine release, but its major effect is releasing stored serotonin and blocking its reuptake, thus prolonging serotonin’s feel-good flood.
MDMA or Ecstasy
Helps control alertness and arousal.
Norepinephrine
