Complete Solutions
acetylcholine - ANS-a chemical in the brain for activation of the cortex
actigraph - ANS-a device used to measure movement, usually over long periods of time
active sleep - ANS-former name of sleep in infants - REM in adults
adjustment insomnia - ANS-short-term insomnia associated with a specific stressor
advanced sleep phase syndrome - ANS-a circadian rhythm disorder in which the
sleep/wake cycle is advanced with respect to time clock
alpha rhythm - ANS-EEG activity in the 8-13 Hz range, mostly seen in the occipital
regions of the brain
alveolar hypoventilation - ANS-a disorder characterized by periods of shallow breathing
or decreased airflow associated with oxygen and EEG arousals
amplitude - ANS-voltage of an electrical signal
apnea - ANS-complete cessation of airflow for at least ten seconds during sleep.
attenuation - ANS-marked decrease in amplitude of wave
BEnzodiazepines - ANS-class of drugs that tranquilizes or sedates patient
BEta activity - ANS-high frequency, usually high amplitude. Greater than 13Hz
Biofeedback - ANS-insomnia treatment - patient learns to control biological activity
Bipolar montage - ANS-a channel setup based on recording from 2 exploring electrodes
cardio-pneumograph - ANS-a device for measuring respiratory effort that uses two
chest electrodes to record changes in impedance by measuring current flow in AC
circuit
cataplexy - ANS-a common symptom of narcolepsy characterized by a brief loss of
muscle tome with resulting with resulting weakness. usually triggered by strong emotion
, chronotherapy - ANS-a treatment for circadian rhythm disorders - adjusting sleep/wake
up times to reset biological clocks
common mode rejection - ANS-the process by which a differential amplifer rejects
indentical inputs
common mode rejection ratio - ANS-a rating of the ability of a differential amplifier to
eliminate identical inputs
DC amplifier - ANS-an amplifier that processes slowly changing electrical signals. a DC
amplifier does not require the use of frequency filters and does not have negative
signals
dofferential amplifier - ANS-an amplifier used in PSG which works by comparing the
difference between incoming voltages and outputs a signal based on the difference
diurnal - ANS-term referring to something that occurs during the daytime
dopamine - ANS-a chemical in the brain that is responsible for arousal of the cortex.
movement, and responsiveness
electrical baseline - ANS-vertical position of a pen when the power to the amplifier is
turned on
Epileptiform discharge - ANS-EEG activity indicating a seizure
fall time - ANS-amount of time for a calibration wave to fall from peak to 37% of the
peak
GABA gamma-amniobutyric acid - ANS-a neurotransmitter in the brain involved in
relaxation, sleep, decreased emotional reaction and sedation
gain control - ANS-sensitivity control of the amplifier
glutamate - ANS-excitatory amino acids t hat project to the cortex, forebrain, and
brainstem
ground loop - ANS-when 2 grounds are used a signal can loop through both grounds
causing interference
grounding - ANS-practice of providing a path of least resistance for electricity to allow a
safe flow of current
hypnagogic - ANS-referring to the transition from wakefulness to sleep
