We report a 27 old male patient was admitted to emergency room due to altered consciousness and vomiting. The patient declared that he smoked herbal incense named Bonzai.

Phrenological Controversy and the Medical Imagination: 'A Modern Pythagorean' in Blackwood's Edinburgh Magazine.

Clio medica 2014 Megan J Coyer

The periodical press in the early nineteenth century was a site of dynamic exchange between men of science and men of letters, and Blackwood's Edinburgh Magazine was a particularly rich site of expression for medical ideas. This chapter explores the symbiotic relationship between the Blackwoodian prose fiction and the scientific and medical investigations of the Glaswegian surgeon and writer,...

EPA-1610 - Basic self-disturbance in psychosis: integrating phenomenology and neurosciences

European Psychiatry 2014 Pauline Monhonval, Christian Widakowich, Juan Martin Tecco

Recent theoretical and empirical work indicates renewed interest in the study of subjective experience in psychopathology (1,2). Phenomenological research shown that disturbance of the basic sense of self may be a core marker of the schizophrenia spectrum (3). This selfdisturbance occurs at the tacit, pre-reflective level of selfhood, where it exists a disruption of the sense of ownership of...

Epileptic qualia and self-awareness: a third dimension for consciousness.

Epilepsy & Behavior January 2014 Lutfu Hanoglu, Çiğdem Özkara, Betül Yalçiner et al.

Over the last few decades, there has been increasing awareness among epileptologists about the need to refine our understanding and assessment of ictal consciousness, focusing on both subjective and behavioral aspects of seizures. Specifically, there have been suggestions that both the internal and external milieux - the former related to the phenomenal qualia of experience, the latter related...

Sliding perspectives: dissociating ownership from self-location during full body illusions in virtual reality.

Frontiers in Human Neuroscience 2014 Antonella Maselli, Mel Slater

Bodily illusions have been used to study bodily self-consciousness and disentangle its various components, among other the sense of ownership and self-location. Congruent multimodal correlations between the real body and a fake humanoid body can in fact trigger the illusion that the fake body is one's own and/or disrupt the unity between the perceived self-location and the position of the...

Dreams, reality and memory: confabulations in lucid dreamers implicate reality-monitoring dysfunction in dream consciousness.

Cognitive Neuropsychiatry 2014 Philip R. Corlett, S V Canavan, L Nahum et al.

Dreams might represent a window on altered states of consciousness with relevance to psychotic experiences, where reality monitoring is impaired. We examined reality monitoring in healthy, non-psychotic individuals with varying degrees of dream awareness using a task designed to assess confabulatory memory errors - a confusion regarding reality whereby information from the past feels falsely...

Magnetoencephalographic alpha band connectivity reveals differential default mode network interactions during focused attention and open monitoring meditation.

Frontiers in Human Neuroscience 2014 Laura Marzetti, Claudia Di Lanzo, Filippo Zappasodi et al.

According to several conceptualizations of meditation, the interplay between brain systems associated to self-related processing, attention and executive control is crucial for meditative states and related traits. We used magnetoencephalography (MEG) to investigate such interplay in a highly selected group of "virtuoso" meditators (Theravada Buddhist monks), with long-term training in the two...

Mind the gap: an attempt to bridge computational and neuroscientific approaches to study creativity.

Frontiers in Human Neuroscience 2014 Geraint A Wiggins, Joydeep Bhattacharya

Creativity is the hallmark of human cognition and is behind every innovation, scientific discovery, piece of music, artwork, and idea that have shaped our lives, from ancient times till today. Yet scientific understanding of creative processes is quite limited, mostly due to the traditional belief that considers creativity as a mysterious puzzle, a paradox, defying empirical enquiry. Recently,...
