New molecule maps cerebrovascular system

A peptide is capable of binding to the blood-brain barrier that protects the central nervous system and could help create novel imaging tests to diagnose Alzheimer’s and Parkinson’s.

Understanding of atrial fibrillation-related dementia

Researchers have determined that atrial fibrillation (Afib) is independently associated with changes that occur with aging and dementia.

Levels of autism: Everything you need to know

Doctors can diagnose three different levels of autism, which vary in their severity. Getting the correct diagnosis can help ensure that a person receives the right treatment and support. Learn more here.

Is procrastination friend or foe to health and creativity?

In this Spotlight feature, we explore the reasons behind procrastination, look at its effects on health, and ask whether procrastination has any benefits.

Hotspot in the genome may drive psychosis in schizophrenia and bipolar disorder

A newly identified epigenetic hotspot for schizophrenia and bipolar disorder may give scientists a fresh path forward for devising more effective treatments and biomarker-based screening strategies. More than 100 million people worldwide have either sc…

Brain imaging lie detector can be beaten with simple techniques

Researchers have shown that a functional magnetic resonance imaging (fMRI) ‘lie detector’ test, which measures brain activity, can be ‘deceived’ by people using mental countermeasures. The study suggests that more should be done to detect mental counte…

The sense of touch is formed in the brain before birth

All the surface of the human body is represented in the cerebral cortex in a transversal band localized at the external part of the cerebral hemispheres: the somatosensory cortex. Each body region occupies in that band a distinct extension depending on…

These trippy images were designed by AI to super-stimulate monkey neurons

To find out which sights specific neurons in monkeys ‘like’ best, researchers designed an algorithm, called XDREAM, that generated images that made neurons fire more than any natural images the researchers tested. As the images evolved, they started to…

Putting vision models to the test

Neuroscientists have performed the most rigorous testing yet of computational models that mimic the brain’s visual cortex. The results suggest that the current versions of these models are similar enough to the brain to allow them to actually control b…

Connecting neurons in the brain

Researchers have uncovered new mechanisms of brain development that determine when, where and how strongly distinct brain cells interconnect.
