Which type of meds increase activity in the reticular activating system?

Answer 2

Stimulants

Question 3

Which medication type increases beta and peak alpha and decreases slower activity?

Answer 3

Stimulants

Question 4

Which drug depletes dopamine quickly, and increases delta and theta power?

Answer 4

Meth

Question 5

Which drug, if used excessively, alters the GABA and glutamate balance in the brain?

Answer 5

Alcohol

Question 6

Which drug increases frontal alpha, phase synchrony, and alpha coherence?

Answer 6

Marijuana

Question 7

What drug increases beta in most people, and can cause convulsions at higher doses but inhibit convulsions at lower doses?

Answer 7

LSD

Question 8

Which drug triggers more slow wave activity as well as paroxysms, which can be dangerous in high doses?

Answer 8

PCP

Question 9

Which drug produces a rhythmic 18-26 Hz activity in the front that eventually spreads to the entire cortex?

Answer 9

Barbituates

Question 10

Which medication type increases delta and alpha, creates alpha slowing over time, and increases REM sleep?

Answer 10

Opiates

Question 11

What does alcohol do to the brain of someone with low voltage?

Answer 11

It causes the sudden occurrence of alpha waves

Question 12

Which medication type increases coherence, sharp theta transients, temporal transients, and decreases beta?

Answer 12

Tranquilizers

Question 13

Which medication is most commonly given to children who are having seizures?

Answer 13

Phenobarbital

Question 14

Which medication types decrease alpha but increase sinusoidal beta in the 18-25 Hz range (sometimes up to 30 Hz)?

Answer 14

Benzodiazepenes

Question 15

What mood-specific medication makes slower activity slower and the faster activity faster, while decreasing alpha?

Answer 15

Lithium

Question 16

Which type of antidepressant med lowers frontal theta and increases fast alpha?

Answer 16

SSRI’s

Question 17

Antipsychotic medications reduce _______ waves, but also create instability in the EEG.

Answer 17

beta

Before what age is a low voltage record a sure sign of abnormality?

Answer 18

13

Question 19

Central nervous system addiction patterns are related to which phenotypes?

Answer 19

Fast alpha, low voltage fast, and beta spindles. Also, midline frontal theta can be associated with this.

Question 20

You should be suspicious of an EEG with predominant activity from ______ to ______ Hz because it likely indicates drug effects.

Answer 20

15-25 Hz beta

Question 21

What drug reduces power for slow beta and fast alpha?

Answer 21

Caffeine

Question 22

What drug can increase peak alpha by up to 2 Hz?
