This paper discusses the nature of consciousness' intrinsic intentionality from a transcendental-phenomenological viewpoint. In recent philosophy of mind the essentially intentional character of consciousness has become obscured because the latter is predominantly understood in terms of "qualia" or the "what-it-is-like-ness" of mental states and it is hard to see why such subjective "feels", of...
Abstract There are two ways to account for the nature of phenomenologically presented ownership constitutive of the "immersed" self. One sees it as fundamentally a relationship of bodily ownership: the theory of a core self as bodily feeling of presence to oneself is a bodily account of immersion. Other accounts develop an analysis out of a more detailed study of the structure of...
From its discovery in the early 1990s until this day, the error-related negativity (ERN) remains the most widely investigated electrophysiological index of cortical error processing. When researchers began addressing the electrophysiology of subjective error awareness more than a decade ago, the role of the ERN, alongside the subsequently occurring error positivity (Pe), was an obvious locus of...
One of the greatest challenges of modern neuroscience is to discover the neural mechanisms of consciousness and to explain how they produce the conscious state. We sought the underlying neural substrate of human consciousness by manipulating the level of consciousness in volunteers with anesthetic agents and visualizing the resultant changes in brain activity using regional cerebral blood flow...
This article does not directly consider the feelings and emotions that occur in mental illness. Rather, it concerns a higher level methodological question: To what extent is an analysis of feelings and felt emotions of importance for psychiatric classification? Some claim that producing a phenomenologically informed descriptive psychopathology is a prerequisite for serious taxonomic endeavor....
Neuropsychological studies have underlined the significant presence of distinct brain correlates deputed to analyze facial expression of emotion. It was observed that some cerebral circuits were considered as specific for emotional face comprehension as a function of conscious vs. unconscious processing of emotional information. Moreover, the emotional content of faces (i.e. positive vs....
Depersonalization disorder (DPD) is a psychiatric condition in which there is a pervasive change in the quality of subjective experience, in the absence of psychosis. The core complaint is a persistent and disturbing feeling that experience of oneself and the world has become empty, lifeless, and not fully real. A greatly reduced emotional responsivity, or “de-affectualization,” is frequently...
This paper addresses the phenomenology of bodily feeling in depersonalization disorder. We argue that not all bodily feelings are intentional states that have the body or part of it as their object. We distinguish three broad categories of bodily feeling: noematic feeling, noetic feeling, and existential feeling. Then we show how an appreciation of the differences between them can contribute to...
The abuse of MDMA (Ecstasy) peaked in the early 2000s, yet reports of MDMA use from emergency room admission data continue to increase. The potential for cardiovascular effects of MDMA to contribute to its acute toxicity has long been recognized. However, the role of MDMA metabolites in mediating the drug's cardiovascular actions has not been studied. Here we employed radiotelemetry to evaluate...

This article follows the culmination of the scientific thought of the neurobiologist Christfried Jakob (1866-1956) during the later part of his career, based on publications from 1930 to 1949, when he was between 64 and 83 years of age. Jakob emphasized the necessity of bridging philosophy to the biological sciences, neurobiology in particular. Thus, we consider him as one of the early...
