New study reveals brain networks are involved in 'cross-modal' person recognition

Human social interactions are shaped by our ability to recognise people. Faces and voices are known to be some of the key features that enable us to identify individual people, and they are rich in information such as gender, age, and body size, that lead to a unique identity for a person.

Certain patterns of brain activity allow 'seeing' two colours at the same time

The Nobel prize-winning physicist Richard Feynman once wrote in his autobiographical book (What do you care what other people think?): "When I see equations, I see letters in colors - I don't know why […] And I wonder what the hell it must look like to the students."

Text messaging effectively intervenes during smoking urges

A pair of related studies on smoking cessation by researchers at the University of Oregon and other institutions have isolated the brain regions most active in controlling urges to smoke and demonstrated the effectiveness of text-messaging to measure and intervene in those urges.

Tobacco smoking leads to less activity in the 'executive center' of brain

Tobacco smoking is the leading preventable cause of death and disease in the U.S., with more than 400,000 deaths each year attributable to smoking or its consequences. And yet teens still smoke. Indeed, smoking usually begins in the teen years, and approximately 80 percent of adult smokers became hooked by the time they were 18. Meanwhile, teens who don't take up smoking usually never do.

Study: Visual cortex can dramatically change its function

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex.

Stripe of Gennari in the blind may play greater role in processing tactile stimuli

The Stripe of Gennari develops even in those who are blind from birth and does not degenerate, despite a lack of visual input. This was discovered by Robert Trampel and colleagues from the Max Planck Institute for Human Cognitive and Brain Sciences using magnetic resonance imaging. This bundle of nerve fibers, which is approximately 0.3 mm thick, is not exclusively responsible for optic information.
