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.

Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia

Sulforaphane, a compound derived from broccoli sprouts, may be a useful new treatment for those suffering from schizophrenia. In a recent set of animal and human studies, researchers characterized novel chemical imbalances in the brain related to glutamate. Levels of glutamate, they discovered, can be altered by administering sulforaphane.
