Deciphering how the brain encodes color and shape There are hundreds of thousands of distinct colors and shapes that a person can distinguish visually, but how does the brain process all of this information? Scientists previously believed that the visual system initially encodes shape and color with different sets of neurons and then combines them much later.  Read More
More Common Ground Than Conflict in Video Game Data Perspectives on Psychological Science After a mass shooting in the US, politicians often renew the call for restrictions on violent video games, but scientific studies have yielded varied findings about the link between those video games and violent acts. Even meta-analyses — studies that synthesize existing research findings — have produced conflicting conclusions. Read More

Our brain uses a not-so-instant replay to make decisions
The hippocampus is a small curl of brain, which nests beneath each temple. It plays a crucial role in memory formation, taking our experiences and interactions and setting them in proverbial stone by creating new connections among neurons. Read More.

Scientists study headbanging parrot to learn why music makes us dance Snowball the dancing parrot doesn’t just bob his head when he hears music. He headbangs. He headbangs with a lifted foot. He vogues. You may already be familiar with Snowball, the sulphur-crested cockatoo who scientists proclaimed the first non-human dancer back in 2014 because he could move to a beat (poorly, yes, but much more coordinated than random movement).

Stress changes the brain, and this could be how it happens The results of a new brain imaging study may have just answered a big question about how stress changes the brain. Using a combination of genetic editing and brain scanning in mice, researchers found that stress triggers a chemical cascade that radically changes how brain networks communicate, and the results could sharpen our understanding of anxiety disorders in humans.

The brain’s pathways to imagination may hold the key to altruistic behavior In those split seconds when people witness others in distress, neural pathways in the brain support the drive to help through facets of imagination that allow people to see the episode as it unfolds and envision how to aid those in need, according to a team of Boston College researchers.

The science of smiles, real and fake Back in the 1800s, Charles Darwin was among the first to come up with what modern scientists further developed into the "facial feedback hypothesis." That's the idea that smiling can make you happier and frowning can make you sadder or angrier — that changing your facial expression can intensify or even transform your mood. Read More
Unraveling mechanisms of speech processing in the brain CUNY via Neuroscience News Mouse models reveal different specializations between the left and right auditory cortex. Researchers identified differences in the wiring diagrams between the sides of the cortex that may explain their specific roles in speech processing. Read More.
