Music-induced emotions can be predicted from brain scans

Researchers have discovered what type of neural mechanisms are the basis for emotional responses to music. Altogether 102 research subjects listened to music that evokes emotions while their brain function was scanned with functional magnetic resonance…

Astrocytes eat connections to maintain plasticity in adult brains

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while connections dee…

How our brains track where we and others go

A new study reveals how your brain navigates places and monitors someone else in the same location. The findings suggest that our brains generate a common code to mark where other people are in relation to ourselves.

AI-designed serotonin sensor may help scientists study sleep and mental health

Researchers have described how they used advanced genetic engineering techniques to transform a bacterial protein into a new research tool that may help monitor serotonin transmission with greater fidelity than current methods. Preclinical experiments,…

The brain’s protein factories at work

Protein synthesis is a finely tuned process in the cell by macromolecules known as ribosomes. Which regulators are responsible for controlling protein synthesis in the brain? To address this question, researchers studied the structure of the brain’s ri…

Mouse-controlled mouse helps researchers understand intentional control

Researchers have devised a brain machine interface (BMI) that allows mice to learn to guide a cursor using only their brain activity. By monitoring this mouse-controlled mouse moving to a target location to receive a reward, the researchers were able t…

Anti-diarrhea drug drives cancer cells to cell death

In cell culture, loperamide, a drug commonly used against diarrhea, proves effective against glioblastoma cells. A research team has now unraveled the drug’s mechanisms of action of cell death induction and – in doing so – has shown how this compound c…

Scientists discover mutations associated with early onset dementia

Scientists have announced a significant advance in our understanding of an early onset form of dementia that may also progress our understanding of conditions such as Alzheimer’s disease. Adult onset Leukoencephalopathy with axonal Spheroids and Pigmen…

Brain tissue yields clues to causes of PTSD

A post-mortem analysis of brain tissue from people who had been diagnosed with post-traumatic stress disorder (PTSD) may help explain enduring mysteries about the disorder, such as why women are more susceptible to it and whether a dampened immune syst…
