Math Ability Requires Crosstalk in the Brain

A new study finds strength of communication between the left and right brain hemispheres predicts performance on basic arithmetic problems. Findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia - an inability to understand and manipulate numbers.

The Seat of Meta-Consciousness in the Brain

Studies of lucid dreamers visualise which centers of the brain become active when we become aware of ourselves. Studies demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained.

Controlling Monkey Brains and Behavior With Light

Researchers can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The findings represent a key advance for optogenetics, a state-of-the-art method for making causal connections between brain activity and behavior. Researchers say that similar light-based mind control could likely also be made to work in humans for therapeutic ends.

Suspicion Resides in Two Regions of the Brain

Our baseline level of distrust is distinct and separable from our inborn lie detector. Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech...

Brain Network Reveals Disorders

Researchers at ETH Zurich and the University of Zurich identify a new method of unerringly detecting the presence of pathophysiological changes in the brain. The new method was developed in order to gain a...

Scientists Search for Source of Creativity

It takes two to tango. Two hemispheres of your brain, that is. USC researchers are working to pin down the exact source of creativity in the brain and have found that the left hemisphere of your brain,...

An Off Switch for Pain

Chemists build light-controlled neural inhibitor. The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and...
