Evolutionary Psych
Come from the same egg and sperm and share the same DNA
Identical Twins
Chemical messengers that cross the synaptic gaps
Neurotransmitters
A nerve cell; the basic building block of the nervous system
Neuron
What is the gap between neurons that neurotransmitters must cross
Synaptic gap
Nurons that carry info from the body's tissues and organs to the brain and spinal cord.
Sensory Neuron
Evolutionary psychologists would suggest if you had to keep one child alive you would choose the male or female
male
This neurotransmitter considered the pleasure chemical that is iinvolved in reward and addiction and too much of it plays a role iin schizophrenia
Dopamine
A neuron’s reaction of either firing (with a full-strength response) or not firing.
All-or-none-response
What is the level of stimulation (-55mv) called that is required to trigger a neural impulse?
Threshold
the division of the autonomic nervous system that calms the body, conserving its energy and calms us.
Parasympathetic
All of our genetic code that makes us up to conception is considered
nature
Too little of this neurotransmitter is linked to depression
Serotonin
a branch of psychology that studies the links between biological (including neuroscience and behavior genetics) and psychological
Biological Psychology
What is the name of the process when a sending neuron reabsorbs excess neurotransmitters
Reuptake
An inhibitory neuron that allows us to rest and too little of it is connected to insomnia
GABA
The idea the the best of genetics will weed out the weak genes over time
natural selection
Our body's natural pain killer
Endorphins
a change in a cell's electrical charge distribution that results in a less negative charge inside the cell than outside
Depolorization
Drugs that block the receptors of a neuron to prevent certain neurotransmitters from getting through
Antagonist
the body's "slow" chemical communication system; a set of glands that secrete hormones into the blood stream.
Endocrine
The idea that was used at various times in history to only allow reproduction from the "best" people
Eugenics
This neurotransmitter enables muscle action, learning, and memory and too little of is connected to Alzhiemer's disease
Acetylcholine (ACh)
The resting time below -70mv when a neuron cannot re-fire
Refractory Period
(excite) A drug molecule that is similar to the neurotransmitter that mimics its effects or blocks it's reuptake. Opium.
Agonist
ÂDiseases such as multiple sclerosis are a result of damage to this part of the neuron
