Twenty-two female volunteers ranging in age from nineteen to fifty-four were asked to practice self-hypnosis and visual imagery in an attempt to enlarge the breasts. All subjects had some enlargement. The subjects who were able to visualize the greatest percentage of times tried had the greatest increase in breast size.

I wish that would work my brain, too.

Tanz scheint über eine verstärkte Oxytocin-Ausschüttung der Hypophyse eine stabilere Gedächtnisbildung zu bewirken.8[Huron, D. (2006). Sweet anticipation: music and the psychology of expectation. Cambridge, Massachusetts: A Bradford Book]

In einer kürzlich erschienenen Arbeit aus der Gruppe von Robert Zatorre wurde die Ausschüttung von Dopamin bei intensiven
Gänsehauterlebnissen durch Musik beschrieben. Dabei wurden die Hirnregionen aktiviert, die im Mittelhirn, im Accumbens-Kern, im
Striatum sowie im unteren vorderen Stirnhirn für die Vermittlung von
Belohnungs- und Glücksgefühlen zuständig sind. Interessanterweise war die Ausschüttung des Motivations- und Belohnungshormons Dopamin im Striatum einige Sekunden vor dem eigentlichen Glücksgefühl in der Phase der Erwartung der »Gänsehaut« nachweisbar, während die Glückserfahrung selbst zur Dopamin-Ausschüttung im Accumbens-Kern führte.15
[Salimpoor, V.N., Benovoy, M., Larcher, K., Dagher, A., Zatorre, R.J. (2011). Anatomically distinct dopamine release during anticipation and experience of peak emotion to music. Nature Neuroscience, 14, 257-262.]
Einen ähnlichen Verlauf der neurohormonalen Ausschüttung
findet man auch bei anderen stark lustbetonten Aktivitäten, etwa beim Essen nach längerer Hungerperiode oder bei sexueller Aktivität. Solche Ergebnisse können auch erklären, warum Musik in allen menschlichen Gesellschaften ein so hoher Wert beigemessen wird. Die oben beschriebene dopaminerge Aktivierung reguliert und erhöht die Aufmerksamkeit, unterstützt Motivation und Gedächtnisbildung im episodischen und prozeduralen Gedächtnis.

http://en.wikipedia.org/wiki/Subliminal_...plications

Chakalis E, Lowe G. from Department of Psychology, University of Hull, UK. did a study to assess the effect of subliminally embedded auditory material on short-term recall, where 60 volunteer subjects undertook a face-name-occupation memory test before and after a 15-min. intervention. They were randomly assigned into three groups (a control group and two experimental groups) and allocated to one of the following conditions: (1) no sound, (2) supraliminal presentation of relaxing music, and (3) subliminal presentation of memory-improvement affirmations embedded in relaxing music. After intervention, only the subliminal group significantly improved their performance on recall of names."[40] Borgeat et al. (1989) could show that long term effects of subliminal stimuli can still be observed on a physiological level 15 minutes after subliminal presentation.[41]

Mal ne andere Idee:

Oft spüren sie eine Anwesenheit, eine Art Engel oder Dämon, der aber unsichtbar ist. Sowohl kranke als auch gesunde Personen können diese Erlebnisse haben – allerdings treten sie bei ihnen in unterschiedlichen Zusammenhängen auf.


[...]

Drei Regionen der Großhirnrinde interessierten die Forscher besonders. Es waren die Areale, die für die eigene Körperwahrnehmung wichtig sind: der insulare Cortex, der parietal-frontale Cortex und der temporo-parietale Cortex.

Diese Hirnregionen sind immer dann aktiv, wenn die Position des Körpers oder eines Körperteils im Raum bestimmt wird, bei Bewegungen und beim Bewusstwerden des eigenen Selbst. Im Gehirn der Probanden mit Epilepsie konnten die Forscher Schäden in diesen Hirnregionen feststellen.

[...]

Im Experiment verbanden die Wissenschaftler ihren Probanden die Augen und ließen sie Bewegungen mit ihren Händen vor ihrem Körper durchführen. Immer wenn die Teilnehmer ihre Hand beispielsweise von links nach rechts bewegten, strich gleichzeitig eine Roboterhand dem Probanden mit der gleichen Bewegungsrichtung über den Rücken, von links nach rechts.

Dadurch wurde eine räumliche Diskrepanz in der Wahrnehmung erzeugt – die das Gehirn aber wegen der Gleichzeitigkeit der Bewegung von eigener Hand und echter Hand sofort ausgleichen konnte.


Als nächstes sorgten die Wissenschaftler für eine zeitliche Verzögerung zwischen der Bewegung der Hand und der streichelnden Roboterhand. Das war offenbar zu viel für das Gehirn der Probanden. Denn unter diesen Bedingungen spürten sie plötzlich eine Geisterillusion.

Wichtig im Experiment war, dass die Probanden keine Ahnung hatten, was überhaupt getestet werden sollte. Drei Minuten nach dem Ende des Experimentes wurden sie von den Wissenschaftlern befragt, was sie empfunden hatten. Instinktiv berichteten mehrere Teilnehmer, sie hätten das Gefühl einer "Präsenz" gehabt, manche gaben sogar an, sie hätten "Geister" gespürt.

"Manche Probanden fühlten diese Illusion sogar so stark, dass sie uns baten, das Experiment abzubrechen", sagt Wissenschaftler Giulio Rognini, der die Studie leitete. Es war zu viel für die Teilnehmer, zu unangenehm.

Das erinnert mich ein wenig an die Empfindungen, die beim WILDen ausgelöst werden. Was passiert nun, wenn man das Experiment oder eine ähnliche Routine beim WILDen macht? (man könnte die Sachen nur mit dem vorgestellten Körper machen)

Als Klarträumer hat man auch das geistige Rüstzeug, um mit den Empfindungen umzugehen (siehe Tholey: Dialog)





Eine andere Idee: die VerBraS-Technik.

Es gibt ja die recht unbekannte Technik der CoBraS-Methode. Dabei wird vor dem Einschlafen der präfrontale Cortex durch innere Bilder stimuliert.

Was passiert aber, wenn man die für die Klarheit zuständige Bereiche des Gehirnes nicht durch innere Bilder stimuliert, sondern indem man mit ihnen geistig redet.
Als Beispiel: Sag mal telepathisch eine Zeit lang zu deiner Hand: "Liebe Hand, bitte werde warm". Die Hand wird tatsächlich warm.
Nun könnte man beim Einschlafen zu seinem Gehirn / präfrontalen Cortex sprechen "Lieber präfrontaler Cortex, bitte bleibe diese Nacht aktiver als sonst".

Cerebral activation patterns during the first three auto-suggestive phases of autogenic training (AT) were investigated in relation to perceived experiences. Nineteen volunteers trained in AT and 19 controls were studied with fMRI during the first steps of autogenic training. FMRI revealed activation of the left postcentral areas during AT in those with experience in AT, which also correlated with the level of AT experience. Activation of prefrontal and insular cortex was significantly higher in the group with experience in AT while insular activation was correlated with number years of simple relaxation exercises. Specific activation in subjects experienced in AT may represent a training effect. Furthermore, the correlation of insular activation suggests that these subjects are different from untrained subjects in emotional processing or self-awareness.

Video gaming is a highly pervasive activity, providing a multitude of complex cognitive and motor demands. Gaming can be seen as an intense training of several skills. Associated cerebral structural plasticity induced has not been investigated so far. Comparing a control with a video gaming training group that was trained for 2 months for at least 30 min per day with a platformer game, we found significant gray matter (GM) increase in right hippocampal formation (HC), right dorsolateral prefrontal cortex (DLPFC) and bilateral cerebellum in the training group. The HC increase correlated with changes from egocentric to allocentric navigation strategy. GM increases in HC and DLPFC correlated with participants’ desire for video gaming, evidence suggesting a predictive role of desire in volume change. Video game training augments GM in brain areas crucial for spatial navigation, strategic planning, working memory and motor performance going along with evidence for behavioral changes of navigation strategy. The presented video game training could therefore be used to counteract known risk factors for mental disease such as smaller hippocampus and prefrontal cortex volume in, for example, post-traumatic stress disorder, schizophrenia and neurodegenerative disease.

Applied Research Using Alpha/Theta Training for Enhancing Creativity and Well-Being

Introduction. Previous research has supported anecdotal reports of a possible correlation between the state of hypnagogia and the enhancement of creative ability (Green, 1972; Green, Green, & Walters, 1970, 1974; Parks, 1996; Stembridge, 1972; Whisenant & Murphy, 1977). Some psychologists (e.g., Maslow, 1963; Rogers, 1978) have suggested that there is also a correlation between creative ability and enhanced well-being.

Methods. This study utilized an 8-week repeated-measures experimental design to investigate the effects of electroencephalogram (EEG) biofeedback on the willful use of hypnagogia for increasing creativity and well-being. The sample size of 62 (30 experimental subjects and 32 controls) was comprised of both sexes with a mean age of 45. The EEG parameters of hypnagogia were broadly defined as the presence and pre-dominance of alpha and theta brain wave activity. Creativity was defined by the three most readily agreed upon divergent thinking abilities: (a) fluency (the ability to generate numerous ideas), (b) flexibility (the ability to see a given problem from multiple perspectives), and © originality (the ability to come up with new and unique ideas).

Results. Hypnagogia was analyzed through multiple univariate analyses of variance. The EEG data showed that both experimental and control participants were able to achieve light to deep hypnagogic states in every training session. T-tests results on fluency and originality scores from the Torrance Test of Creative Thinking and the Christensen-Guilford Associational Fluency Test showed no significant changes in pre- and post-tests for either group. However, flexibility in thinking, as measured by the Alternate Uses Test was significantly increased (p < .001) for all participants. Well-being, as measured by the Friedman Well-Being Scale, also significantly increased for all participants (p = .002).

Discussion. The data suggest that willful use of hynagogia may indeed increase creativity and well-being. Participants reported increased personal creativity, stress reduction, heightened self-awareness, emotional equanimity, and improved work performance.

The Effects of Caffeine on the Brain: A Review

The effects of caffeine may often be overlooked in neurotherapy. However, caffeine is a potent and widely used drug which is addictive, has withdrawal symptoms associated with discontinued use, and which can produce anxiety and insomnia. It also has a rapid and profound influence on the brain, including producing increases in beta and decreases in slower brain wave activity. In contrast, during withdrawal from caffeine patients may experience increases in theta and delta, with decreases in the mean frequency of both alpha and beta. Recommendations are presented for control of caffeine use associated with EEG assessment and in neurofeedback treatment.

The Role of Slow-Wave Electroencephalographic Activity in Reading

Results. Multiple t-test analyses comparing the three reading tasks with the baseline showed significant amplitude increases during reading mostly in the 1-4 Hz and some in the 4-8 Hz band. These changes were topographically different among the three reading tasks. During visual reading, amplitude increased at C3, C4, T3, T4, and T5 for the 1-4 Hz band, and at T5 and T6 for the 4-8 Hz band. During phonetic reading, amplitude increased at T3, T4, F3 and F7 for the 1-4 Hz band, and at T5 and FP1 for the 4-8 Hz band. During semantic reading, amplitude increased at T3, T4, C3, C4, F3, F7, F8, CZ and FZ for the 1-4 Hz band and at T5 for the 4-8 Hz band.

Social learning in humans and other animals

http://journal.frontiersin.org/article/1...00058/full

Decisions made by individuals can be influenced by what others think and do. Social learning includes a wide array of behaviors such as imitation, observational learning of novel foraging techniques, peer or parental influences on individual preferences, as well as outright teaching. These processes are believed to underlie an important part of cultural variation among human populations and may also explain intraspecific variation in behavior between geographically distinct populations of animals. Recent neurobiological studies have begun to uncover the neural basis of social learning. Here we review experimental evidence from the past few decades showing that social learning is a widespread set of skills present in multiple animal species. In mammals, the temporoparietal junction, the dorsomedial, and dorsolateral prefrontal cortex, as well as the anterior cingulate gyrus, appear to play critical roles in social learning. Birds, fish, and insects also learn from others, but the underlying neural mechanisms remain poorly understood. We discuss the evolutionary implications of these findings and highlight the importance of emerging animal models that permit precise modification of neural circuit function for elucidating the neural basis of social learning.
