Focused ultrasound opening brain to previously impossible treatments

Focused ultrasound, the researchers hope, could revolutionize treatment for conditions from Alzheimer’s to epilepsy to brain tumors — and even help repair the devastating damage caused by stroke.

Genetic variation in a brain-cleansing water channel affects human sleep

The reason why we sleep remains an unresolved question of the 21st century. Research now shows that the depth of non-rapid-eye-movement (nonREM) sleep in humans is associated with different genetic versions of a gene that encodes a water channel involv…

Evidence that human brains replay our waking experiences while we sleep

When we fall asleep, our brains are not merely offline, they’re busy organizing new memories — and now, scientists have gotten a glimpse of the process. Researchers report the first direct evidence that human brains replay waking experiences while asl…

Similar brain glitch found in slips of signing, speaking

The discovery of a common neural mechanism in speech and ASL errors — one that occurs in just 40 milliseconds — could improve recovery in deaf signers after a stroke.

Targeting depression: Researchers ID symptom-specific targets for treatment of depression

For the first time, physician-scientists have identified two clusters of depressive symptoms that responded to two distinct neuroanatomical treatment targets in patients who underwent transcranial magnetic brain stimulation (TMS) for treatment of depre…

How synaptic changes translate to behavior changes

Learning changes behavior by altering many connections between brain cells in a variety of ways all at the same time, according to a study of sea slugs. The findings offer insight into how human learning can impact widespread brain areas.

From scaffolding to screens: Understanding the developing brain for reading

In the debate about nature versus nurture for developing reading skills, cognitive neuroscientists have a clear message: both matter. From infancy, children have a neural scaffolding in place upon which environmental factors build reading skills. Scien…

Exercise boosts motor skill learning via changes in brain’s transmitters

Comparing the brains of mice that exercised with those that did not, researchers found that specific neurotransmitters switched following sustained exercise, leading to improved learning for motor-skill acquisition. Underscoring the critical benefits o…

Neural circuit that drives physical responses to emotional stress found

Researchers have discovered a neural circuit that drives physical responses to emotional stress. Emotional stress signals are processed in the ”emotion” circuits and integrated in the DP/DTT. The integrated signals are transmitted to the hypothalamus…

Parkinson’s dyskinesia mechanism explained

The mechanism underlying Parkinson’s dyskinesia has been unknown, until now. An international collaboration has found a key cause, and with it, potentially, a new route to providing relief.
