Schizophrenia itself is associated with loss of excitation, but hallucinations and other symptoms of the disorder are caused by a loss of synaptic inhibition.
Researchers find a region of the brain stem called the periaqueductal gray may mediate religiosity and spirituality in humans.
Study reveals people who experience intense visual imagery during a Ganzflicker test have naturally lower frequency rhythms in the visual cortex, making them more susceptible to pseudo-hallucinations.
PsychLight, a newly developed genetically encoded fluorescent sensor, helped researchers identify a psychedelic compound that acts on beneficial neural pathways to treat psychiatric disorders without the hallucinogenic effect.
Mouse study reveals elevated dopamine levels preceded hallucination-like events, and artificially boosting dopamine levels induced more hallucination-like events. The behavioral effects could be blocked by administering haloperidol, an antipsychotic wh…
Loneliness, stress, and social isolation as a result of COVID-19 exacerbated and intensified visual hallucinations in blind people with Charles Bonnet Syndrome by 56%.
Inducing hallucinations using visual stimuli in a lab setting enables more objective and reliable testing.
Hallucinations and delusions share a common neurobiological mechanism while simultaneously depending on symptom-specific pathways.
8% of patients with a history of seizures reported experiencing hallucinations. Of the 8%, 53% reported one or more suicide attempts. Findings suggest hallucinations associated with seizures are not just incidental but are a marker for mental health ri…
A new study reports hyper-connectivity between substructures of the thalamus, and the cerebral cortex may be responsible for auditory hallucinations associated with schizophrenia.
