Abstract:

Behrendt & Young (B&Y) propose that a dysfunction in the reticular thalamic nucleus contributes to disinhibition of specific thalamic nuclei, allowing cortical attention mechanisms to engage thalamic relay neurons, causing underconstrained activation of the cortex and hallucinations. The following hypothesis challenges the notion of impaired sensory gating by providing the alternative view that hypofrontality reduces the power of incoming stimuli, causing internal drives to override consciousness, resulting in hallucinations.
