Electrical properties of dendrites help explain our brain’s unique computing power

Neuroscientists have discovered that human dendrites have very different electrical properties from those of other species. These differences may contribute to the enhanced computing power of the human brain.

Brain cells called astrocytes have unexpected role in brain ‘plasticity’

Researchers have shown that astrocytes — long-overlooked supportive cells in the brain — help to enable the brain’s plasticity, a new role for astrocytes that was not previously known. The findings could point to ways to restore connections that have…

Study points to new method to deliver drugs to the brain

Researchers have discovered a potentially new approach to deliver therapeutics more effectively to the brain. The research could have implications for the treatment of a wide range of diseases, including Alzheimer’s, Parkinson’s, ALS, and brain cancer.

Colored filter improves dyslexic children’s reading speed

Volunteers aged 9-10 with dyslexia took less time to read passages from children’s books, possibly thanks to attenuated excitability of the cerebral cortex.

Bee social or buzz off: Study links genes to social behaviors, including autism

A new study found that the social lives of sweat bees — named for their attraction to perspiration — are linked to patterns of activity in specific genes, including ones linked to autism.

Mice need a clutch to smell

Researchers identify shootin 1b as a clutch molecule that couples force and adhesion for the migration of neurons to the mouse olfactory bulb. The study provides new insights on how internal forces are converted into external movement and on how mechan…

Hormone alters male brain networks to enhance sexual and emotional function

Scientists have gained new insights into how the ‘master regulator’ of reproduction affects men’s brains.

How does brain structure influence performance on language tasks?

The architecture of each person’s brain is unique, and differences may influence how quickly people can complete various cognitive tasks. But how neuroanatomy impacts performance is largely an open question. To learn more, scientists are developing a n…

Stem cell proliferation is controlled directly by nervous system, scientists find

A new study demonstrates that stem cell proliferation is directly controlled by the autonomic nervous system.

Alzheimer’s: These psychiatric symptoms may be an early sign

A postmortem study of brain tissue tests and interviews of those close to the deceased ties some psychiatric symptoms to early Alzheimer’s disease.
