Prof John Gruzelier

 

JOHN GRUZELIER is Emeritus Professor of Psychology, joining Goldsmiths as a Professorial Research Fellow in 2006 from the medical faculty of Imperial College London where he had a department of Cognitive Neuroscience before its merger with the Division of Neuroscience and Mental Health.
Keywords for research include: EEG-Neurofeedback, Cognitive Peak Performance, Creativity, Performing Arts, EEG oscillations, Brain & Hypnosis, Self-Hypnosis/Visualisation & Immune Function, Energy Medicine, Schizophrenia, Schizotypy.

Research Interests

Validation of EEG-Neurofeedback

The primary research focus this millennium through validation studies, mainly involving healthy participants (Gruzelier, 2014a), and following demonstration of the promise of neurofeedback in schizophrenia (Gruzelier et al, 1999). Protocols were chosen mostly from clinical practice as were initial outcome measures such as the CPT and P300 (Egner and Gruzelier, 2001, 2004a). Coincidentally longstanding interests in creativity in the performing arts were incorporated encompassing elite and novice music performance, contemporary and competitive dancing, and acting (Gruzelier, 2014b). Funding has included NARSAD (USA); Leverhulme Trust; Saugstad Fund; Cerebra; National Endowment for Science, Technology & Arts (NESTA); EU Future Emerging Technologies (FET): Presencia; Brain Health; German Science Council (DFG); NIHR Research for Patient Benefit; Chang Gung Memorial Hospital, Taiwan; ARK; Evens Foundation www.evensfoundation.be.


To promote validation an international society was inaugurated in Europe - the Society of Applied Neuroscience (SAN: www.applied-neuroscience.org); the field of EEG-neurofeedback had been neglected by mainstream science. Meetings were initially with the EU COST B27 initiative on EEG and cognition (www.cost.eu/domains_actions/bmbs/Actions/B27 ), with biennial SAN meetings in Turkey, Wales, Greece, the Netherlands (www. SAN2014.org). Three SAN journal special issues were published in 2014:

Neuroscience & Biobehavioral Reviews, 44, 1 -3. 05/2014; DOI: 10.1016/j.neubiorev.2014.05.003. van Boxtel, G.J.M., Gruzelier, J.H.

Progress in validating the EEG-neurofeedback field has been the subject of a 3-part review:

Complimentary & Alternative Interventions


Following development of an empirically-based, dynamic multi-stage brain model of hypnotic induction (see Gruzelier, 1998, 2006; Eves et al, 2005; Ernest Hilgard award 2004), the efficacy of self-hypnosis training in enhancing immune function and well-being during exam stress and in patients with chronic viral infections was explored in controlled trials (Gruzelier, 2002a,b); psychoneuroimmunology interests followed MRC funded research on the natural history and interventions in early stage HIV infection. Interventions were later extended to 3D-assisted visualisation, methods of energy healing (Johrei, Reiki), yogic meditation (brain wave vibration, mindfulness and Iyenga yoga), and acustimulation.


Editorship of Contemporary Hypnosis & Integrative Therapies (2002 - 2012) contributed to promotion of the field; recipient for 'leadership and achievement in hypnosis 'of Society of Clinical & Experimental Hypnosis, USA, 2011 Raginski award. Funding included the MRC; Institut für Grenzgebiete der Psychologie/ Psychohygiene, Germany; EU Future Emerging Technologies (FET); Johrei Foundation; Korean Institute of Brain Sciences.
