Pseudo-Hallucinations: Why Some People See More Vivid Mental Images Than Others – Test Yourself Here

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.

Mice With Hallucination-Like Behaviors Reveal Insight Into Psychotic Illness

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 which blocks dopamine. The study sheds light on potential new treatments for psychotic disorders marked by hallucinations.

Hallucinations in people with seizures may point to suicide risk

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 risks and suicidal behavior.

How strong is your mental imagery? It might depend on how ‘excitable’ your neurons are

The strength of a person's mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person's ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.

Ayahuasca DMT compound changes brainwaves to vivid ‘waking-dream’ state

DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.
