Although Wang cautions that we are still a long way from testing this in humans, in theory, if we could someday use drugs or electrical stimulation or some other method of activating the D2 neurons--these so-called "no-go" neurons--then we...
EPFL scientists propose a new way of understanding of how the brain processes unconscious information into our consciousness. According to the model, consciousness arises only in time intervals of up to 400 milliseconds, with gaps of unconsciousness in between.
The...
Not all habits are bad. Some are even necessary. It's a good thing, for example, that we can find our way home on "autopilot" or wash our hands without having to ponder every step. But inability to switch from...
Green: NAc-projecting prefrontal cortex neurons become active during the presentation of a reward-predictive cue, and this activity drives reward-seeking behavior.

A new Carnegie Mellon University neuroimaging study reveals the mental stages people go through as they are solving challenging math problems.
Published in Psychological Science, researchers combined two analytical strategies to use functional MRI (fMRI) to identify patterns of brain...
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a "bionic eye" that could...
Researchers have overcome a major challenge to treating brain diseases by engineering an experimental molecular therapy that crosses the blood-brain barrier to reverse neurological lysosomal storage disease in mice.

Over the past few years, scientists have faced a problem: They often cannot reproduce the results of experiments done by themselves or their peers.
This "replication crisis" plagues fields from medicine to physics, and likely has many causes. But one...
Samir Haj-Dahmane, Ph.D., senior research scientist at the University at Buffalo Research Institute on Addictions, has discovered how certain neurotransmitters are transported and reach their targets in the brain, which could lead to new drug therapies to help anxiety...
Mice with the genetic defect that causes Fragile X syndrome (FXS) learn and remember normally, but show an inability to learn new information that contradicts what they initially learned, shows a new study by a team of neuroscientists. FXS...
Girls are often said to be better at reading than boys. At least, that is what international reading studies like PIRLS and PISA show. Image Credit: Flickr/breadfortheworld
In reading tests at school, girls tend to be ahead of boys, in...
