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’re not moving

16
Q

non-REM 3

A

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

17
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

18
Q

endocrine system

A

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

19
Q

pituitary gland

A

The endocrine system’s most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.

20
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

21
Q

adrenal glands

A

a pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the body in times of stress

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

anandamide

A

The Bliss Molecule; also known as an endocannabinoid; increases naturally with prolonged aerobic exercise and increased Omega 3 in diet; neurotransmitter

24
Q

dopamine

A

The Reward Molecule; increases naturally by setting goals and achieving them; neurotransmitter

25
Q

oxytocin vasopressin

A

The Bonding Molecules; hormones that increase bonding with others; increases naturally with hugs or petting animals

26
Q

endorphin

A

The Pain-Killing Molecule; hormone & 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

27
Q

GABA

A

The Anti-Anxiety Molecule; slows down the firing of neurons and creates a sense of calmness; increases naturally with yoga and meditation; neurotransmitter

28
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

29
Q

adrenaline

A

The Energy Molecule; also called epinephrine; released from adrenal glands, making it a hormone, but a small amount is produced in neurons of the medulla oblongata, making it also a neurotransmitter; plays 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

30
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

31
Q

Hertz

A

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

32
Q

sleep strategies

A

exercise (but not right before bed); avoid caffeine in the afternoon/evening; avoid eating close to your bedtime; avoid blue light emitting devices (backlit black & white reading devices are o.k.)

33
Q

brain wave

A

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

34
Q

love molecules

A

dopamine, serotonin, adrenaline/epinephrine

35
Q

depressants

A

drugs that reduce neural activity and slow body functions (e.g. alcohol)

36
Q

stimulants

A

drugs that excite neural activity and speed up body functions (e.g. caffeine)

37
Q

resistance

A

increased by using the strategy of distraction
