DNA organization influences the growth of deadly brain tumors in response to neuronal signals

A pioneering study has unveiled that the 3D organization of DNA can influence the progression of the aggressive brain tumor known as glioblastoma. Having identified the factors that glioblastoma uses to respond to neurons by growing and spreading, this…

The brain may learn about the world the same way some computational models do

New studies support the idea that the brain uses a process similar to a machine-learning approach known as ‘self-supervised learning.’ This type of machine learning allows computational models to learn about visual scenes based solely on the similariti…

Lab unlocks keys to alcohol withdrawal headache

Researchers have discovered mechanisms by which specific cells are activated in alcohol withdrawal-induced headache. The research may benefit further studies of various substance use disorder mechanisms including withdrawal. It may be possible to dev…

Want to achieve your goals? Get angry

While often perceived as a negative emotion, anger can also be a powerful motivator for people to achieve challenging goals in their lives, according to new research.

fMRI study finds correlated shifts in brain connectivity associated with overthinking in adolescents

A new study substantiates previous groundbreaking research that rumination (overthinking) can be reduced through an intervention called Rumination-focused Cognitive Behavioral Therapy (RF-CBT). In addition, the use of fMRI technology allowed researcher…

Hidden way for us to feel touch

Researchers have discovered a hidden mechanism within hair follicles that allow us to feel touch.

An unexpected link between 2 schizophrenia risk proteins

The discovery of a physical interaction between two proteins in brain cells that can be traced in mice to control of movement, anxiety and memory could one day open the door to development of new schizophrenia treatment strategies, researchers say.

Perception–but not expectation–of reward is altered in people with cocaine addiction

Researchers report that cocaine addiction disrupts the dopamine neurons that govern how we perceive and learn from rewards. Though people with cocaine addiction have similar expectations of rewards compared to controls, their dopamine neurons send out …

Marijuana use may damage brain immune cells vital to adolescent development, study suggests

In a mouse study designed to explore the impact of marijuana’s major psychoactive compound, THC, on teenage brains, researchers say they found changes to the structure of microglia, which are specialized brain immune cells, that may worsen a genetic pr…

New clue to treat brain cancer

A new research study shows that cerebrospinal fluid reduces current treatment efficacy in brain cancer and identifies new therapeutic opportunities. Cerebrospinal fluid, the clear colourless liquid that protects the brain, also may be a factor that mak…
