A Multidisciplinary Hypothesis about Serotonergic Psychedelics. Is it Possible that a Portion of Brain Serotonin Comes From the Gut?

Journal of Integrative Neuroscience August 31, 2022 Noémi Császár-nagy, Petr Bob, István Bókkon 9 citations

Here we present a complex hypothesis about the psychosomatic mechanism of serotonergic psychedelics. Serotonergic psychedelics affect gut microbes that produce a temporary increase of 5-HT by their host enterochromaffin cells (ECs). This increased 5-HT production—which is taken up and distributed by platelets—may work as a hormone-like regulatory signal that could influence membrane...

A novel Wim Hof psychophysiological training program to reduce stress responses during an Antarctic expedition

Journal of International Medical Research April 1, 2022 Tereza Touskova, Petr Bob, Zdenek Bares et al. 15 citations

OBJECTIVE: The aim of this prospective observational study was to investigate the effects of a novel Wim Hof psychophysiological training program on stress responses and hormone release in healthy participants during an Antarctic expedition. METHODS: All members of an Antarctic expedition were included in the study. The participants were healthy volunteers allocated to an intervention group (n...

Traumatic stress, neural self and the spiritual mind.

Consciousness and Cognition November 1, 2016 Petr Bob, Matthew Laker

According to recent findings stressful experiences may influence various physiological disturbances and also neuroanatomical changes and some studies also show that psychotherapy and meditation may influence brain functions. Traumatic stress is frequently related to a dissociative response that disintegrates conscious experience. In this context, self-reflection is an essential principle in the...

Dissociative states in dreams and brain chaos: implications for creative awareness

Frontiers in Psychology September 7, 2015 Petr Bob, Olga Louchakova 14 citations

This article reviews recent findings indicating some common brain processes during dissociative states and dreaming with the aim to outline a perspective that neural chaotic states during dreaming can be closely related to dissociative states that may manifest in dreams scenery. These data are in agreement with various clinical findings that dissociated states can be projected into the "dream...

'Pseudoneurological' symptoms, dissociation and stress-related psychopathology in healthy young adults.

BMC Psychiatry May 25, 2013 Petr Bob, Petra Selesova, Jiri Raboch et al.

Background: Somatoform dissociation is a specific form of dissociation with somatic manifestations represented in the form of 'pseudoneurological' symptoms due to disturbances or alterations of normal integrated functions of consciousness, memory or identity mainly related to trauma and other psychological stressors. With respect to the distinction between psychological and somatoform...

Conscious Attention, Meditation, and Bilateral Information Transfer

Clinical EEG and Neuroscience 2013 Petr Bob, Elizabeth M. Zimmerman, Elizabeth A. Hamilton et al.

Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres,...

Schizophrenia, dissociation, and consciousness.

Consciousness and Cognition May 23, 2011 Petr Bob, George A. Mashour

Current thinking suggests that dissociation could be a significant comorbid diagnosis in a proportion of schizophrenic patients with a history of trauma. This potentially may explain the term "schizophrenia" in its original definition by Bleuler, as influenced by his clinical experience and personal view. Additionally, recent findings suggest a partial overlap between dissociative symptoms and...

Dissociative states and neural complexity.

Brain and Cognition March 2011 Petr Bob, Miroslav Světlák

Recent findings indicate that neural mechanisms of consciousness are related to integration of distributed neural assemblies. This neural integration is particularly vulnerable to past stressful experiences that can lead to disintegration and dissociation of consciousness. These findings suggest that dissociation could be described as a level of neural disintegration reflecting a number of...

Pain, dissociation and subliminal self-representations.

Consciousness and Cognition March 2008 Petr Bob

According to recent evidence, neurophysiological processes coupled to pain are closely related to the mechanisms of consciousness. This evidence is in accordance with findings that changes in states of consciousness during hypnosis or traumatic dissociation strongly affect conscious perception and experience of pain, and markedly influence brain functions. Past research indicates that painful...

Dissociation and neuroscience: history and new perspectives.

International Journal of Neuroscience July 2003 Petr Bob

History of the study of dissociation begins in the second half of the nineteenth century. It begins in the works of Hughlings Jackson and Pierre Janet, and markedly influences development of psychoanalysis and other psychological trends. According to the modern definition, dissociation represents a disturbance or alteration in the normally integrative functions of identity, memory, or...
