CORRECT ANSWERS
Why is neurofeedback used? - CORRECT ANSWERS To change the electrical activity of the
CNS including EEG, event related potentials, slow cortical potentials, and other electrical activity
either of subcortical or cortical region
Neurofeedback is: - CORRECT ANSWERS A specialized application of biofeedback of brain
wave data in an operant conditioning paradigm. It is used to treat clinical conditions as well as
to enhance performance.
Electroencephalogram (EEG) - CORRECT ANSWERS Represents the general state of the
CNS: all behavior filters through the central nervous system.
Biofeedback therapy: - CORRECT ANSWERS Any physiologic mechanism that can be 'fed
back' to an individual's awareness that can be controlled
Neurofeedback therapy - CORRECT ANSWERS Allows the subject to gain control over the
brain's processing function (reflected by the EEG) and of the primary mechanics of their own
psychophysiology.
The purpose of neurofeedback is to bring rapid electrical and chemical changes to a person's
brain in order to: - CORRECT ANSWERS 1. Disrupt pathologic stability by altering the type
of electrochemical pattern that developed either suddenly or during shock or trauma, or
gradually over a longer period of time, under prolonged stress.
2. Allow patients to release defenses, recognize and use new information (psychotherapy,
counseling, education) with greater ease by diminishing interference from problematic brain-
chemistry patterns.
,Neurofeedback is socio-behavioral interaction. Important factors include: - CORRECT
ANSWERS -Attitudes
-Motivation
-Expectations
-Attention
-Alertness
-Understanding
Delta rhythm (0.5-3.5 hz) - CORRECT ANSWERS Sleep, traumatic brain injury
Theta rhythm (4-7 hz) - CORRECT ANSWERS Day dreaming, drowsiness imagery,
inattention
Alpha rhythm (8-13 hz) - CORRECT ANSWERS Meditation, receptiveness
Sensorimotor rhythm (SMR) (12-15 hz) - CORRECT ANSWERS Inhibition of movement
Low beta rhythm (13-21 hz) - CORRECT ANSWERS Activation, focused thinking
High beta rhythm (20-32 hz) - CORRECT ANSWERS Anxiety, hypervigilance, panic, peak
performance, worry
Gamma rhythm (36-44) - CORRECT ANSWERS Active attention, pattern recognition, visual
binding
, The synchronous delta rhythm: - CORRECT ANSWERS Ranges from 1-4 hz, is the dominant
frequency from ages 1-2, and is associated in adults with deep sleep and brain pathology like
TBI and tumors, and learning disability
The synchronous theta rhythm: - CORRECT ANSWERS Ranges from 4-7 hz, is the dominant
frequency in healthy young children, and is associated with drowsiness or starting to sleep, REM
sleep, hypnagogic imagery (intense imagery experienced before the onset of sleep) hypnosis,
attention, and processing of cognitive and perceptual information
The synchronous alpha rhythm: - CORRECT ANSWERS Ranges from 8-12 hz and is defined
by its waveform and not by its frequency.
Alpha blocking (phenomenon): - CORRECT ANSWERS Alpha activity can be observed in
about 75% of awake, relaxed individuals and is replaced by low-amplitude desynchronized beta
activity during movement, complex problem-solving, and visual focusing.
The synchronous SMR: - CORRECT ANSWERS Ranges from 12-15 hz and is located over the
sensorimotor cortex (central sulcus).
The sensorimotor rhythm is associated with: - CORRECT ANSWERS The inhibition of
movement and reduced muscle tone
The beta rhythm consists of: - CORRECT ANSWERS Asynchronous waves and can be
divided into low beta and high beta ranges (13-21 hz and 20-32 hz)
Low beta is associated with: - CORRECT ANSWERS Activation and focused thinking
High beta is associated with: - CORRECT ANSWERS Anxiety, hypervigilance, panic, peak
performance, and worry
