How humans learn to optimize working memory

Working memory is what allows humans to juggle different pieces of information in short-term scenarios, like making a mental grocery list and then going shopping or remembering and then dialing a phone number. While scientists agree that the capacity o…

The brain perceives unexpected pain more strongly

Researchers used visual threat manipulation in the virtual reality environment and thermal stimulation to investigate how the brain perceives pain. They found that the brain perceives pain more strongly when the perceived pain is out of alignment with …

Brain-wide activity change visualized as geometric patterns

Researchers have applied a visualization technique to depict the brain’s activity related to visual perception as geometric patterns. They visualized different shapes as the ever-changing neuronal activity in the temporal and frontal lobes of the brain…

Breathing and vision may be linked

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation — something that could affect our vision.

Framework to identify food selectivity origins in the brain

Human evolution has revolved around food, from identifying and foraging for it to growing and preparing it. Researchers have identified a region in the brain’s visual cortex that responds to food and have developed a theoretical framework that could ex…

Blood pressure drug could be a safer alternative for treating ADHD symptoms

Repurposing amlodipine, a commonly used blood pressure medicine, could help manage attention-deficit/ hyperactivity disorder (ADHD) symptoms, according to an international study.

Study reveals activity of navtemadlin in glioblastoma, points to possible treatment improvements

Clinical research suggests that combining a novel agent called navtemadlin with DNA-damaging chemotherapy for the treatment of glioblastoma, a form of brain cancer, could increase efficacy. Navtemadlin is an MDM2 inhibitor that can help to kill cancer …

Mutation increases enzyme in mouse brains linked to schizophrenia behaviors

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, report researchers.

Scientists solve the brain’s motion-source separation problem

Neuroscientists have discovered how the brain distinguishes between visual motion occurring in the external world from that caused by the observer moving through it. Known as the ‘motion-source separation problem,’ researchers have long wondered how th…

‘Healthy’ vitamin B12 levels not enough to ward off neuro decline

Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough — particularly if you are older. It may even put you at risk for cognitive impairment.
