Psychology. The autonomic nervous system, auto pilot, glands, internal organ muscles, sympathetic nervous system,
parasympathetic nervous system
This page is about
Psychology, especially "The autonomic nervous system is involved in keeping your body on auto pilot, especially with respect to your glands and internal organ muscles. Its sympathetic nervous system arouses the body during stressful situations by mobilizing needed energy. The autonomic system's parasympathetic nervous system calms the body to conserve energy."
Dick's Guide to Psychology. The autonomic nervous system is involved in keeping your body on auto pilot, especially with respect to your glands and internal organ muscles. Its sympathetic nervous system arouses the body during stressful situations by mobilizing needed energy. The autonomic system's parasympathetic nervous system calms the body to conserve energy..

Guide to Psychology. In psychological
research the aim is to get reliability, replicable results, representative
results and validity.
In psychological research the population of an experiment is "all the cases in a group from which samples may be drawn to study"
In psychological research a random sampling is "a sample that fairly represents a population because each member has an equal chance of inclusion"
In psychological experiments, the independent variable is manipulated to see how it affect the dependent variable, i.e. behavior or mental process
Psychological research can involve experiments
that explore cause and effect relationships, correlational studies that determine naturally occurring relationships and
descriptive studies that record and observe behavior
Franz Gall (early 1800's) invented phrenology to determine peoples' mental abilities and character traits by studying the bumps on people's heads.
Phineas Gage was a railroad employee in 1848 whose frontal lobe was impaled by a metal rod. His mental abilities and memories were intact, but his personality changed. From a soft spoken, friendly guy he became an irritable, profane and dishonest.
A neuron is a "nerve cell; the basic building block of the nervous system", where "bushy dendrites receive information while axons pass it along to other neurons, muscles or glands"
The myelin sheath "insulates the axons of some neurons and helps speed their impulses". In multiple sclerosis the myelin sheath decays.
A synapse is the junction at which the axon of one neuron sends chemical messengers (neurotransmitters) to the dendrites of another nerve cell.
Guide to Psychology. Neurotransmitters
include dopamine which "influences movement, learning, attention and emotion.
Too much has been linked to schizophrenia. Serotonin affect mood, hunger, sleep
and arousal. Norepinephrine helps control alertness and arousal. Cocaine aids arousal, too. Endorphins are natural opiates and pain killers.
Agonists increase the likelihood of a neuron firing while antagonists inhibit firing by blocking dendrite synapses, aiding reuptake or increasing the enzymatic kill rate of neurotransmitters
The blood-brain barrier fences out unwanted chemicals circulating in the blood. It also blocks out dopamine which explains why people can not be injected with dopamine.
The two primary divisions of the nervous system are the central nervous system and the peripheral nervous system, The peripheral nervous system is divided into the autonomic and somatic systems.
The somatic nervous system is involved in voluntary movements. Afferent nerves fibers are involved in sensory signals while efferent nerve fibers are involved in creating motion.
The autonomic nervous system is involved in
keeping your body on auto pilot, especially with respect to your glands and
internal organ muscles. Its sympathetic nervous system arouses the body during
stressful situations by mobilizing needed energy. The autonomic system's
parasympathetic nervous system calms the body to conserve energy.
