Current neuroscience evidence suggests several brain areas are involved in the generation of hallucinations including the sensory cortex, insula, putamen, and hippocampus. But how does activity in these regions give rise to aberrant <jats:italic>conscious<\/jats:italic> perceptions that seemingly invade ongoing <jats:italic>conscious<\/jats:italic> experience? Most existing models assume that sensory representations are sometimes spontaneously activated in the brain, and that these spontaneous activations somehow play a causal role in the generation of hallucinations. Yet, it remains unclear how these representations become <jats:italic>selected<\/jats:italic> for conscious processing. No existing theory of hallucinations has specified such a \u201cselection mechanism.\u201d Global Workspace (GW) theorists argue that the brain\u2019s interconnected processors select relevant piece(s) of information for broadcasting to other brain processors, rendering the information accessible to consciousness; this process known as \u201cignition\u201d is associated with synchronized activity across distributed cortical and subcortical brain regions. Yet, it remains unclear how certain information and representations become selected for conscious processing. While GW theorists maintain that attention plays an important role, they have not delineated a formal \u201cselection mechanism.\u201d This paper specifies a selection mechanism based upon two central hypotheses: (1) a functional network called the \u201csalience network\u201d plays a critical role in selecting sensory representations for conscious broadcast to the GW in normal (healthy) perception; (2) sensory representations become abnormally <jats:italic>selected<\/jats:italic> for conscious broadcast to the GW (instead of being filtered out of consciousness) in individuals with SSD that experience hallucinations.<\/jats:p>","DOI":"10.3389\/fnins.2021.733038","type":"journal-article","created":{"date-parts":[[2021,11,30]],"date-time":"2021-11-30T12:36:40Z","timestamp":1638275800000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Hallucinations: A Functional Network Model of How Sensory Representations Become Selected for Conscious Awareness in Schizophrenia"],"prefix":"10.3389","volume":"15","author":[{"given":"Stephanie M.","family":"Hare","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,11,23]]},"reference":[{"key":"B1","year":"2013","journal-title":"Diagnostic and Statistical Manual of Mental Disorders"},{"key":"B2","author":"Arguinchona","year":"2021","journal-title":"Neuroanatomy, Reticular Activating System."},{"key":"B3","author":"Baars","year":"1988","journal-title":"A Cognitive Theory of Consciousness."},{"key":"B4","first-page":"292","article-title":"In the theatre of consciousness.
