Schizophrenia, intoxication with tetrahydrocannabinol (Delta-THC), and cannabis psychosis induce characteristic time and space distortions suggesting a common psychotic dysfunction. Since genetic research into schizophrenia has led into disappointing dead ends, the present study is focusing on this phenotype. It is shown that information theory can account for the dynamical basis of higher...
Even during well-calibrated cognitive tasks, successive brain responses to repeated identical stimulations are highly variable. The source of this variability is believed to reside mainly in fluctuations of the subject's cognitive "context" defined by his/her attentive state, spontaneous thought process, strategy to carry out the task, and so on... As these factors are hard to manipulate...
This chapter sees into the mountain slopes of the Himalayas, where Tibetan monks who have spent many years in training and learning Buddhist philosophy and psychology, live in a retreat far from the secular world. These well educated monks have taken the brave step of joining forces with scientists to help with the understanding of how hours of meditation can have a substantial effect on...
While some process philosophers have denigrated the emergent theory of mind, what they have denigrated have been ‘materialist’ theories of emergence. My contention is that one of the most important reasons for embracing process philosophy is that it is required to make intelligible the emergence of consciousness. There is evidence that this was a central concern of Whitehead. However, Whitehead...
An ontological need persisted in the writing of Ted Hughes, and continues in critical responses to it. This has manifested itself in various forms: Leonard Scijay detects a ‘mystical consciousness of the oneness of Creation’; in his recent book The Laughter of Foxes: A Study of Ted Hughes, Keith Sagar eulogises the ‘inner being’ of the poet. Although different, these descriptions share a vague...
Confusional states associated with medical and surgical conditions require more study and biochemical explanation. To understand impairment of consciousness, cognition and memory. A psychiatrist reports experience of his changing mental state over 5 days from notes made immediately on recovery. A prodromal phase of declining consciousness, understanding and memory registration over perhaps 48 h...
A hallmark of Christian mysticism is negative theology, which refers to the school of thought that gives prominence to negation in reference to God. By denying the possibility to name God, negative theology cuts at the very root of our cognitive makeup—the human impulse to name and put things into categories—and thereby situates us “halfway between a ‘no longer’ and a ‘not yet’” (Iser, 1978, p....
This review presents an account of the areas and circuits of the brain that are thought to be involved in such cognitive functions as memory, affect and consciousness. Considerable progress has been made in the past two decades in the identification of the cerebral areas and in our understanding of the brain mechanisms involved in these functions, thanks in large parts to a number of imaging...

It has been suggested that the two cerebral hemispheres play different roles in the maintenance and updating of an individual's beliefs. In particular it has been suggested that the left hemisphere (LH) forms consistent beliefs, whereas the right hemisphere (RH) monitors for inconsistencies or anomalies in reference to these beliefs. If some threshold of inconsistencies is detected, the role of...
