Hermann von Helmholtz’s work on perceptual science had a fundamental impact on Neo-Kantian movements in the late nineteenth century, and his influence continues to be felt in psychology and analytic philosophy of perception. As is widely acknowledged, Helmholtz denied that we can perceive mind-independent properties of external objects, a view I label Ignorance. Given his commitment to...
IF ketamine were an animal, it would have to be an octopus: unique, endlessly mutable, potentially dangerous, devilishly complicated to study, and seeming to extend its grasp into every corner of medicine. In the 50 years ketamine has been commercially available in the United States, practitioners and researchers have called it an analgesic, antidepressant, anti-inflammatory agent, dissociative...
We read with great interest the editorial by Krüger (2020) in which she provides a review of some of the cultural aspects of dissociation and trauma. We especially appreciate her call for the study of the “entire spectrum of dissociation” (p. 1) from normal to pathological. We have been working along similar lines (e.g., Maraldi et al., 2017; Maraldi et al., 2019) and would like to take the...
Although phenomenal consciousness resists explanation in physical terms, it remains an open question whether or not consciousness is an intrinsically physical phenomenon since it remains an open question whether or not conscious states are identical with physical states. This question is one of the key issues of debate in contemporary philosophy of mind. Here I survey some of the key arguments...
Episodic memory (EM) is classically conceived as a memory for events, localized in space and time, and characterized by autonoetic consciousness (ANC) allowing to mentally travel back in time and subjectively relive an event. Building on recent evidence that the first-person visual co-perception of one's own body during encoding impacts EM, we used a scene recognition task in immersive virtual...
Propofol is a short-acting medication that results in decreased levels of consciousness and is used for general anesthesia. Although it is the most commonly used anesthetic in the world, much remains unknown about the mechanisms by which it induces a loss of consciousness. Characterizing anesthesia-induced alterations to brain network activity might provide a powerful framework for...
The scope of human consciousness includes states departing from what most of us experience as ordinary wakefulness. These altered states of consciousness constitute a prime opportunity to study how global changes in brain activity relate to different varieties of subjective experience. We consider the problem of explaining how global signatures of altered consciousness arise from the interplay...
Background: Depersonalization and derealization are currently considered diagnostically distinct from first-rank symptoms (FRS) seen in schizophrenia-spectrum psychoses. Nevertheless, the lived experiences of these symptoms can be very similar phenomenologically. Aims: To investigate the interrelationships between depersonalization, derealization and FRS in patients with different types of...
An accessible and engaging account of the mind and its connection to the brain. The mind encompasses everything we experience, and these experiences are created by the brain—often without our awareness. Experience is private; we can't know the minds of others. But we also don't know what is happening in our own minds. In this book, E. Bruce Goldstein offers an accessible and engaging account of...
In the interpretation of the body in the 20th century, philosophy placed less emphasis than before on its natural composition and sought to integrate value judgements from different perspectives. The philosophy of the body addresses the deepest essential problems of human society and culture, it generates a uniquely detailed analysis of human nature and its various roles and performances in...
