A neural model of the loss of self in schizophrenia

Schizophrenia Bulletin
J G Taylor


Numerous researchers have pointed out over the last decades that there is a loss of the sense of the inner self in schizophrenia. In particular, the illuminating article of Sass et al. gives an underpinning explanation of the disease along these lines in each of its 3 manifestations, with positive, negative, or disordered symptoms. The crucial component of the analysis of these researchers is that of various disturbances in ipseity (the ongoing sense of "being there" accompanying all conscious experience) that can occur for a sufferer, giving a framework with which to understand the disease. Such analyses of schizophrenia in terms of distortions of the self go back much earlier. However, the more recent work has become more precise and embracing in terms of seeing most forms of schizophrenia as arising from such distortions. It also provides new ways of looking at and diagnosing the disease. In this article we propose to move the whole analysis closer into the brain itself by means of the CODAM neural network model of consciousness (where CODAM is an acronym for the "COrollary Discharge of Attention Movement" model of consciousness creation, to be described later). This allows both a mechanism to be formulated as to the basic b...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
