Beginning with Sigmund Freud and J. Breuer&s;s observations in Studies on Hysteria , the theme of the "splitting of consciousness" and the question of the location of the subject within this "dual consciousness" has reverberated through the succeeding century of analytic thought. This chapter discusses aspects of the concept of the dialectically constituted and decentered subject of...

The cerebellum plays a key role not only in motor function but also in affect and cognition. Although several psychopathological disorders have been associated with overall cerebellar dysfunction, it remains unclear whether different regions of the cerebellum contribute uniquely to psychopathology. Accordingly, we compared seed-based resting-state functional connectivity of the anterior...

Ketamine is a non-competitive N-Methyl-D-Aspartate (NMDA) receptor antagonist whose effect in subanesthetic doses has been studied for chronic pain and mood disorders treatment. It has been proposed that ketamine could change the perception of nociceptive stimuli by modulating the cortical connectivity and altering the top-down mechanisms that control conscious pain perception. As this is a...

This chapter investigates some of the main meditative techniques practiced in Thailand, as well as what it feels like to practice them and improve over time. It begins with an ethnographic encounter with a man who has just spent a month in meditation at Wat Rampoeng in Chiang Mai, and then follows the author’s personal experience at five different meditation retreats to learn about mindfulness...

Abstract This paper is a response to the new book by Alexander Wendt (2015) entitled Quantum Mind. The paper commends Wendt on the book's contribution to our understanding, particularly of quantum mechanics, panpsychism, and externalism in the philosophy of mind. At the same time, it takes issue with Wendt's overall thesis, particularly as it relates to materialism, emergentism, and social...

BackgroundDespite its designation as a 'dissociative anaesthetic,' the dissociative and psychoactive effects of ketamine remain incompletely understood. The goal of this study was to characterise the subjective experiences and accompanying EEG changes with subanaesthetic doses of ketamine.MethodsHigh-density EEG was recorded in 15 human volunteers before, during, and after subanaesthetic...

According to the free energy principle all living systems aim to minimise free energy in their sensory exchanges with the environment. Processes of free energy minimisation are thus ubiquitous in the biological world. Indeed it has been argued that even plants engage in free energy minimisation. Not all living things however feel alive. How then did the feeling of being alive get started? In...

General anesthesia (GA) is a reversible manipulation of consciousness whose mechanism is mysterious at the level of neural networks leaving space for several competing hypotheses. We recorded electrocorticography (ECoG) signals in patients who underwent intracranial monitoring during awake surgery for the treatment of cerebral tumors in functional areas of the brain. Therefore, we recorded the...

The hard problem in consciousness is the problem of understanding how physical processes in the brain could give rise to subjective conscious experience. In this paper, I suggest that in order to understand the relationship between consciousness and the physical world, we need to probe deeply into the nature of physical reality. This leads us to quantum physics and to a second explanatory gap:...
