A predictive processing theory of sensorimotor contingencies: Explaining the puzzle of perceptual presence and its absence in synesthesia

Cognitive Neuroscience January 21, 2014 Anil K. Seth 357 citations

Normal perception involves experiencing objects within perceptual scenes as real, as existing in the world. This property of "perceptual presence" has motivated "sensorimotor theories" which understand perception to involve the mastery of sensorimotor contingencies. However, the mechanistic basis of sensorimotor contingencies and their mastery has remained unclear. Sensorimotor theory also...

Therapeutic infusions of ketamine: Do the psychoactive effects matter?

Drug and Alcohol Dependence January 15, 2014 Elias Dakwar, C. Anerella, Carl L. Hart et al. 125 citations

Background Sub-anesthetic ketamine infusions may benefit a variety of psychiatric disorders, including addiction. Though ketamine engenders transient alterations in consciousness, it is not known whether these alterations influence efficacy. This analysis evaluates the mystical-type effects of ketamine, which may have therapeutic potential according to prior research, and assesses whether these...

The Effects of Acutely Administered 3,4-Methylenedioxymethamphetamine on Spontaneous Brain Function in Healthy Volunteers Measured with Arterial Spin Labeling and Blood Oxygen Level–Dependent Resting State Functional Connectivity

Biological Psychiatry January 10, 2014 Robin Carhart-Harris, Kevin Murphy, Robert Leech et al. 182 citations

The MTLs appear to be specifically implicated in the mechanism of action of MDMA, but further work is required to elucidate how the drug's characteristic subjective effects arise from its modulation of spontaneous brain activity.

This drug was available on the internet and in 'head shops' and was one of the most commonly sold legal highs up until its recent UK temporary ban (UK Home Office). Despite its prominence, very little is known about its...

There are many interpretations of what consciousness is. In the past decade materialist and reductionist theories have gained in popularity as many neurological correlates of consciousness have been identified experimentally. This article presents a neurogenetic account of the underpinnings of neuron-based consciousness. In this paradigm, human consciousness is supported by genes that are...

A Short Note on Pseudohallucinations

Psychopathology 2014 Mark A. Turner 9 citations

Pseudohallucinations are poorly understood, with clinicians continuing to rely on historical contributions to inform their views. There have been a number of recent attempts to develop a phenomenologically adequate theory of psychotic symptoms, yet the reciprocal dependence between the structure of such theories and the understanding of pseudohallucinations remains unexploited. This paper seeks...
