The relatively slow brain waves of a relaxed, awake state.
Alpha waves
Two Lima bean sized neural clusters in the limbic system; linked to emotions
Amygdala
The part of the peripheral nervous system that controls the glands and the muscles of the internal organs(such as the heart) Its sympathetic divisions arouses; its parasympathetic division claims
Autonomic nervous system
The neuron extension that passes messages through its branches to other neurons or to muscles or glands
Axon
The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; the brain stem is responsible for automatic survival functions
Brain stem
An observation technique in which one person is studied in depth in the hope of revealing universal principles
Case Study
The brain and spinal cord
Central nervous system
The “little brain” at the rear of the brain stem; functions include processing sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
Cerebellum
Failing to notice changes in the environment
Change blindness
The biological clock; regular bodily rhythms (for example, of temperature and wakefulness) That occurs on a 24-hour cycle
Circadain rhythm
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them
Corpus callosum
A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other.
Correlation
The large, slow brain waves associated with deep sleep
Delta waves
A neuron’s bushy branching extensions that receive messages and conduct impulses toward the cell body
Dendrites
Drugs such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions
Depressants
A split in consciousness which allows some thoughts and behaviors to occur simultaneously with others
Dissociation
The body’s slow chemical communication system. a set of glands that secrete hormones into the bloodstream
Endocrine system
Portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgment
Frontal lobe
Psychedelic (‘mind manifesting”) drugs, such as LSD, that distort perceptions that evoke sensory images in the absence of sensory input
Hallucinogens
The tendency to believe after learning an outcome that one would have foreseen it.(also know know as the I know it all along
Hindsight bias
A neural center located in the limbic system; helps process explicit memories for storage
Hippocampus
A social interaction in which one person (the hypnotist) suggest to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
Hypnosis
A neural structure lying below (hypo) the thalamus; it directs several maintenance activities (eating, drinking, body temperature) helps govern the endocrine system via the pituitary gland and is linked to emotions and reward
Hypothalamus
Recurring problems in falling or staying asleep
Insomnia
