Aberrant Salience: Definition and Historical Context Aberrant salience is a foundational concept in contemporary psychopathology, offering a compelling neurobiological framework for understanding the emergence of positive psychotic symptoms, particularly delusions and hallucinations, most prominently observed in schizophrenia. Salience, in its typical function, refers to the cognitive process by which the brain attributes motivational, emotional, or […]
Definition and Phenomenology Auditory Hallucination, often abbreviated as AH, is defined formally as a sensory perception that occurs in the absence of an external stimulus and is perceived by the individual as real and compelling. Unlike an illusion, which is a misinterpretation of an actual external stimulus, an AH is entirely endogenous, yet it possesses […]

Unlike illusions, which involve a misinterpretation of a real external sound, hallucinations are internally generated and often experienced with the compelling reality […]
Introduction to Sensory Integration Deficits in Schizophrenia Schizophrenia, a severe chronic psychiatric disorder, is traditionally characterized by positive symptoms such as hallucinations and delusions, and negative symptoms like avolition and affective flattening. However, decades of rigorous psychophysical and neurophysiological research have firmly established that the fundamental pathology of schizophrenia extends deeply into basic sensory processing […]
