Cannabis use in adolescence: Visible effects on brain structure

A collaborative study sheds light on how cannabis use affects brain development in young people, the main one being atrophy of certain regions of the cerebral cortex.

The decision to eat may come down to these three neurons

Manipulating a newly identified neural circuit can curb appetite — or spur massive overeating.

Bilingualism may maintain protection against Alzheimer’s

In a study, researchers use neuroimaging methods to examine brain resilience in regions of the brain linked to language and aging. They found that the hippocampus in bilinguals with Alzheimer’s disease was noticeably larger than those who were monoling…

‘Visual clutter’ alters information flow in the brain

Whether we’re staring at our phones, the page of a book, or the person across the table, the objects of our focus never stand in isolation; there are always other objects or people in our field of vision. How that visual ‘clutter’ affects visual proces…

New study finds partner’s happiness linked to lower stress hormone levels in older couples

Having happy intimate partners might not only lift our moods, but it also helps us manage stress, especially as we age, according to new research. When comparing individuals’ self-reported emotional states and relationship satisfaction with their level…

Crucial role of cerebellum in social and cognitive functioning

Scientists shed light on the often-overlooked role of the cerebellum in both motor and social-cognitive processes. His research contributes to a growing shift in the field of neuroscience, which has traditionally focused on the cerebrum. For decades, t…

Researchers develop 3D atlas of the developing mammalian brain

A team of researchers has created a 3D atlas of developing mice brains, providing a more dynamic understanding of how the mammalian brain develops. This atlas provides a common reference and anatomical framework to help researchers understand brain dev…

A new era of treating neurological diseases at the blood-brain-immune interface

A group of scientists say it’s time to think differently about how to define and treat diseases such as Alzheimer’s and multiple sclerosis.

e-Flower records neuronal activity with electronic petals

A new device consists of four flexible petals equipped with platinum electrodes, which curl around the spheroid when exposed to the liquid that supports the cell structure. This actuation is driven by the swelling of a soft hydrogel, making the device …

Controlling prosthetic hands more precisely by the power of thought

Researchers have developed a novel training protocol for brain-computer interfaces in a study with rhesus monkeys. The method enables precise control of prosthetic hands using signals from the brain alone. Researchers were able to show that the neural …
