Q

REM

A

paradoxical sleep because it is associated with alpha waves typical of wakefulness; vivid dreams; motor cortex is very active but the brain stem is blocking messages so you aren’t moving

Q

Non-REM 2

A

characterized by theta waves; includes sleep spindles and k-complexes which indicate brief bursts of activity

17
Q

Non-REM 3

A

characterized by slow-rolling delta waves; deep sleep; brain is unresponsive to external stimuli, more difficult to awaken individual

18
Q

neurotransmitter

A

chemical messenger released from an axon terminal of a neuron in response to an action potential; it crosses the gap to the receptors on dendrites of adjacent neurons (axon gives and dendrite receives!)

19
Q

endocrine system

A

set of glands that secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells

20
Q

pituitary gland

A

the endocrine system’s most influential gland. under the influence of the hypothalamus, it regulates growth and controls other endocrine glands

21
Q

hypothalamus

A

a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion; produces oxytocin

22
Q

hormone

A

chemical messengers released directly into the blood by the endocrine system; in particular, neurochemicals are released by the hypothalamus and pituitary gland

23
Q

oxytocin and vasopressin

A

the bonding molecules; hormones that increase bonding with others; increases naturally with hugs or petting animals

24
Q

endorphin

A

the pain-killing molecule, hormone AND neurotransmitter;
produced by the pituitary gland and the hypothalamus; increase naturally through strenuous exercise, eating chocolate, smiling and laughing, meditating, singing, and listening to music

25
Q

GABA

A

the anti-anxiety molecule; slows down the firing of neurons and creates a sense of calmness; increases naturally with yoga and mediation, neurotransmitter

26
Q

serotonin

A

the confidence molecule; makes you less sensitive to rejection; bolsters self-esteem; to increase, aerobic exercise, bright light, eat high-protein foods with tryptophan (turkey, salmon) with healthy carbs; produced in intestines and brain, so hormone and neurotransmitter

27
Q

Adrenaline

A

the energy molecule, also called epinephrine; released from adrenal glands, so it’s a hormone, but some of it is produced in neurons of the medulla oblongata, making it also a neurotransmitter; plays a role in fight-or-flight mechanism; creates exhilaration and a surge of energy and alertness, and an increase in heart rate and blood pressure; used in Epi-Pens to treat acute allergic reactions; increase naturally through a high intensity workout

28
Q

amygdala

A

source of raw emotions; located in the limbic system; hyper-stimulated by love; also associated with fight-or-flight responses to stimuli, memory, making decisions, and processing emotions and perceiving the emotions of others

29
Q

Hertz

A

the unit of frequency, equal to one cycle per second; abbrev.: Hz

30
Q

wave

A

a disturbance that transfers energy from one place to another

31
Q

brainwave

A

a pattern of electrical current in the brain caused by neurons communicating, visually represented as a wave

32
Q

frequency

A

the number of complete wavelengths that pass a point in a given time.
