How the human brain solves complex decision-making problems

A new study on meta reinforcement learning algorithms helps us understand how the human brain learns to adapt to complexity and uncertainty when learning and making decisions. A research team succeeded in discovering both a computational and neural mec…

Researchers discover how cellular senescence leads to neurodegeneration

Although a link has been established between chronic inflammation and neurodegenerative diseases, there have been many open questions regarding how cellular senescence, a process whereby cells that stop dividing under stress spew out a mix of inflammat…

Not ‘brains in a dish’: Cerebral organoids flunk comparison to developing nervous system

A new study offers a more restrained perspective on brain organoids suggested for lab experiments, by showing that widely used organoid models fail to replicate even basic features of brain development and organization, much less the complex circuitry …

More than a knee injury: ACL tears cause harmful changes in our brain structure

It’s known that some joint function is often permanently lost after anterior cruciate ligament reconstruction, and re-injury is common even with intensive physical therapy, but it’s unclear why.

Brain networks come ‘online’ during adolescence to prepare teenagers for adult life

New brain networks come ‘online’ during adolescence, allowing teenagers to develop more complex adult social skills, but potentially putting them at increased risk of mental illness, according to new research.

New way to treat stroke using an already FDA-approved drug

Granulocyte colony-stimulating factor (GCSF) is currently used to treat neutropenia due to chemotherapy and has been successfully used for patients who require bone marrow transplants. The study is the first to report on the neuroprotective effect of G…

New insight into how cannabidiol takes effect in the brains of people with psychosis

Researchers have shown that cannabidiol (CBD) alters the brain activity in people with psychosis during memory tasks, making it more similar to the activation seen in people without psychosis during the same tasks.

Unhealthy and unhappy: Mental toll of troubled relationships

Some forms of domestic violence double victims’ risk of depression and anxiety disorders later in life, according to recent research.

Antianxiety and antidepressant effects from a single dose of psychedelic drug persist years later in cancer patients

Following up on their landmark 2016 study, researchers found that a one-time, single-dose treatment of psilocybin, a compound found in psychedelic mushrooms, combined with psychotherapy appears to be associated with significant improvements in emotiona…

New knowledge on how different brain cell types contribute to our movements

Researchers have mapped how different nerve cells in the brain area striatum process information to plan and execute our movements at just the right time and with the right vigor. The results show that different cell types in the striatum receive signa…
