How CBD takes effect in the brains of people with psychosis

During memory tasks, people with psychosis have different patterns of activity in the prefrontal and mediotemporal brain areas compared to those without the disorder. When exposed to cannabidiol (CBD), the activity of the brain areas became more like those seen in the controls for people with psychosis. Patients reported a decrease in symptoms of psychosis following one dose of CBD. Researchers stress that no definitive conclusions could be made about the effectiveness of CBD use over a sustained period.

Squid brains approach that of dogs

The first MRI-based mapping of the squid brain yields 145 new connections and pathways, 60% of which are linked to the motor and visual systems. The new brain map brings researchers one step closer to understanding how the squid can instantly camouflage itself.

High air pollution exposure in 1-year-olds’ linked to structural brain changes at age 12

Early-life exposure to high levels of traffic-related air pollution alters the structure of the brain at age 12. Children exposed to air pollution had reduced cortical thickness and gray matter volume compared to children who were not exposed to high levels of pollution.

Horror movies manipulate brain activity expertly to enhance excitement

Neuroimaging reveals areas of the brain associated with visual and auditory processing are more active when anxiety slowly increases during horror movies. After a shocking scene, brain areas associated with emotional processing, threat evaluation, and decision making increase in activity.

A rat had basically no brain, but it could still see, hear, smell, and feel

Rat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies.
