Chapter 2 - Biology of Mind & Consciousness

Circadian Rhythm

-"regular bodily rhythms… that occur on a 24- hour cycle "(pg.

Hypnagogic sensations

- being startled awake while drifting to sleep.

Narcolepsy

- characterized by "uncontrollable sleep attacks, sometimes lapsing directly into REM sleep "(pg.63)

Parasympathetic

- resting /healing response (after)

Jet Lag

- an individuals internal rhythms are temporarily out of sync with the environment around.

Consciousness

- selective attention to ongoing perceptions, thoughts, and feelings.

Selective Attention

- the focusing of conscious awareness on a particular stimulus.

Sleep Apnea

-"characterized by temporary cessations of breathing during sleep and repeated momentary awakenings.

Symptoms of Jet Lag

- changes in sleep, appetite, mood, motivation, energy levels, susceptibility to illness, etc.

Consciousness

- awareness of ourselves and our environment.

Sympathetic

fight or flight; stress (immediate)

Parasympathetic

resting/healing response (after)

Consciousness

awareness of ourselves and our environment

Consciousness

selective attention to ongoing perceptions, thoughts, and feelings

Selective Attention

the focusing of conscious awareness on a particular stimulus

Change Blindness

Failing to notice changes in the environment

Circadian Rhythm

"regular bodily rhythms… that occur on a 24-hour cycle" (pg

Jet Lag

an individuals internal rhythms are temporarily out of sync with the environment around

Symptoms of Jet Lag

changes in sleep, appetite, mood, motivation, energy levels, susceptibility to illness, etc

Monitored by electroencephalogram (EEG)

"a test that detects electrical activity in your brain using small, flat metal discs (electrodes) attached to your scalp" (mayoclinic.org)

Hypnagogic sensations

being startled awake while drifting to sleep

Difficult to awaken

sleep walking/talking, etc

More rapid brain waves

• brain waves slow down through 1-3, but perk up in REM

Narcolepsy

characterized by "uncontrollable sleep attacks, sometimes lapsing directly into REM sleep" (pg.63)

National Institute of Health (NIH) definition

"A chronic neurological disorder caused by the brains inability to regulate sleep-wake cycles normally"

Medications might help

(uppers and sometimes anti-depressants help symptoms)

Sleep Apnea

"characterized by temporary cessations of breathing during sleep and repeated momentary awakenings"

Obstructive sleep apnea (OSA)

• often with clinically overweight/obese people & kids with enlarged tonsils (snoring)

Central sleep apnea

• CNS struggles with talking to diaphragm and lungs to keep working (stopping breathing)

Surgery

• (resetting of jaw can help)

Central Nervous System

the portion of the nervous system consisting of the brain and spinal cord

Three Types of Neurons

Sensory, Motor, Interneuron

Change Blindness

Failing to notice changes in the environment

Consciousness

selective attention to ongoing perceptions, thoughts, and feelings

Electroencephalogram (EEG)

"a test that detects electrical activity in your brain using small, flat metal discs (electrodes) attached to your scalp"
