Title: Alpha-theta
1Alpha-theta
- The Addicted Brain
- Drug abuse produces long-term changes in the
reward circuitry of the brain
2Electrical stimulation of brains (ESB)
- Electrical stimulation of brains of rats - James
Olds in 1950s - Jacobsen and Torkildsen replicated work in
humans - some epileptics stimulated themselves into
convulsions
3INTRA-CRANIAL SELF-STIMULATION
- Rodent wireheads
- 0.0005 amperes for less than a second whenever
rat pushed lever - Rates of up to 10,000 bar-presses an hour
recorded - Medial forebrain bundle passing through lateral
hypothalamus and ventral tegmentum - An animal will self-stimulate for more than 24
hrs continuously without rest, and will cross
electrified grid to gain access to lever - Other brain centers are aversive, such as
periaqueductal grey matter (PAG) - Ventral tegmental area (VTA) neurons manufacture
dopamine and they are under continuous inhibition
by gamma-aminobutyric acid (GABA) system, an
important component of the final common pathway"
of reward, implicated in addiction, mood, and
learning.

7Alpha-Theta Training
- Peniston Kulkosky (1989)
- Alpha activity deficits in alcoholics known since
1940s - Drinking produces rewarding slow waves (alpha)
- Normal state has much more high beta
- Teach alcoholics to produce alpha without drinking
8Peniston Protocol
- Hand-warming primed EEG biofeedback techniques
- Guided visual imagery during Alpha-Theta
training, especially addict behavior rejecting - O1 site used (Pz by W. Scott)
- Goal is crossover state high theta state
associated with reverie, disidentification with
ego self - Results
- Alcoholism PTSD very low relapse rate, lt20 9
years out - Chemical addicts, ½ relapse rate 18 months out

12MMPI (Minnesota MultiPhasic Inventory)
- Hypochondriasis (Hs) - neurotic concern over
bodily functioning - Depression (D) - symptomatic depression.
- Hysteria (Hy) - hysterical reactions to stress
situations - Psychopathic Deviate (Pd) - psychopathy, asocial,
amoral - Masculinity-Femininity (Mf) - originally
developed to identify homosexual invert males,
now those who reject traditional gender roles.
- Paranoia (Pa) - paranoid symptoms
- Psychasthenia (Pt) - excessive doubts,
compulsions, obsessions, and unreasonable fears
(OCD). - Schizophrenia (Sc) - identify
schizophreniaHypomania (Ma) - hypomanic
disturbances - Social Introversion (Si) - person's tendency to
withdraw from social contacts and
responsibilities.
13MMPI Derived Empirically
- Developers used every personality question they
could find - 1. Tested on various clinical groups
(depressive, schizophrenics, etc.) - 2. Large pool of questions
- 3. Kept only those questions that
- discriminated between groups

15MMPI (Minnesota MultiPhasic Inventory)
- Validity Scales
- "Cannot Say" scale 30 omitted items
invalidates test - L Scale Lie scale - not willing to admit even
minor shortcomings. - F Scale - detect atypical ways of responding to
test items. - K Scale detect subtle attempts at denying
psychopathology or, conversely, at exaggerating
psychopathology overall defensiveness

19Substance Abuse Study OutcomeWilliam Scott,
Thomas Brod, MD, Stephen Siderof Ph.D.,
David Kaiser, Ph.D.,
Meredith Sagan, MD. (2002)
- Crack, Cocaine, Methamphetamine, Heroin
- All participants in 12-step inpatient program
- Control group n61
- Experimental group n60
- 40-session EEG biofeedback added to 12 step
program - Compared abstinence rates, psychometric measures
- UCLA HSPC approved the study design
- 12 month post study (those who completed)
- 36 of 47 experimental subjects were abstinent
- 12 of 27 control subjects were abstinent
- Experimental subjects stayed in treatment
significantly longer (plt 0.005) compared to the
control group - This confirmed and extended earlier studies
20Royal Conservatory of MusicImprovement in
Musical Performance
- Dr. John Gruzelier, Ph.D, Tobias Egner, Ph.D.
Department of Cognitive Neuroscience and
Behavior, Imperial College, London, 2003,
Neuroreport. - Subjects top music students
- Goal could training show measurable improvement
in performance - 15 minute musical performance assessed prior and
subsequent to training. - Performances were video-recorded, randomized and
rated by expert musicians external to the Royal
College of Music. -
- Six groups created each with different
training - Alexander Technique 2) Mental skills 3) Beta NF
- 4) SMR NF 5) Alpha-Theta NF 6) Exercise
21Alpha-Theta neurofeedback group had significant
change in musical improvements
