Scientists reveal brain tumors impact normally helpful cells

Unprovoked recurrent seizures are a serious problem affecting most patients who suffer from glioma, a primary brain tumor composed of malignant glial cells. Researchers tested the hypothesis that glioma-induces processes that renders a type of brain ce…

Stress thwarts our ability to plan ahead by disrupting how we use memory

Pairing brain scans with virtual-navigation tasks, researchers found that people make less efficient and effective plans when stressed.

Lucy had an ape-like brain

A new study led by paleoanthropologists reveals that Lucy’s species Australopithecus afarensis had an ape-like brain. However, the protracted brain growth suggests that — as is the case in humans — infants may have had a long dependence on caregivers.

Chilling concussed cells shows promise for full recovery

In the future, treating a concussion could be as simple as cooling the brain. New findings support the treatment approach at the cellular level.

Gut communicates with the entire brain through cross-talking neurons

You know that feeling in your gut? We think of it as an innate intuition that sparks deep in the belly and helps guide our actions, if we let it. It’s also a metaphor for what scientists call the ‘gut-brain axis,’ a biological reality in which the gut …

The facial expressions of mice

Researchers have described different emotional facial expressions for mice. Similar to humans, the face of a mouse looks completely different when it tastes something sweet or bitter, or when it becomes anxious. With this new possibility to render the …

Potential of using psychedelic drugs in psychiatry

Before they were banned about a half century ago, psychedelic drugs like LSD and psilocybin showed promise for treating conditions including alcoholism and some psychiatric disorders. Researchers say it’s time for regulators, scientists, and the public…

How dopamine drives brain activity

Using a specialized magnetic resonance imaging (MRI) sensor that can track dopamine levels, neuroscientists have discovered how dopamine released deep within the brain influences distant brain regions.

Spina bifida surgery before birth restores brain structure

Surgery performed on a fetus in the womb to repair defects from spina bifida triggers the body’s ability to restore normal brain structure, new research has discovered.

Where in the brain does creativity come from? Evidence from jazz musicians

A new brain-imaging study has studied the brain activity of jazz guitarists during improvisation to show that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, m…
