Researchers find that the brain smells what it expects rather than what it sniffs In the moments before you “stop and smell the roses,” it´s likely your brain is already preparing your sensory system for that familiar floral smell. New research from Northwestern Medicine offers strong evidence that the brain uses predictive coding to generate “predictive templates” of specific smells -- setting up a mental expectation of a scent before it hits your nostrils....

Winning may not be the only thing, but the human brain devotes a lot of resources to the outcome of games, a new study by Yale researchers suggest. The study published in the Oct. 6 issue of the journal Neuron shows that when participants play games, such as rock-paper-scissors, almost the entire brain is engaged, not just the reward centers of the brain, which have been assigned the central role for shaping adaptive human behavior. "Our brain functions to maximize the chance of...

A new study using MRI scans, led by Professor Jianfeng Feng, from the University of Warwick's Department of Computer Science, has found that depression frequently seems to uncouple the brain's "Hate Circuit". The study entitled "Depression Uncouples Brain Hate Circuit" is published today (Tuesday 4th October 2011) in the journal Molecular Psychiatry. The researchers used MRI scanners to scan the brain activity in 39 depressed people (23 female 16 male) and 37 control subjects who were not...

Are We Actually In Love With Our iPhones?

Academic researchers across the Internet were buzzing this weekend over an editorial, which appeared on the New York Times website on Friday, claiming that iPhone users literally "loved" their popular, multi-functional smartphone. "With Apple widely expected to release its iPhone 5 on Tuesday, Apple addicts across the world are getting ready for their latest fix," branding consultant Martin Lindstrom wrote in the opinion piece. "But should we really characterize the intense consumer...

Magnetic resonance tractography (MRT) is a valuable, noninvasive imaging tool for studying human brain anatomy and, as MRT methods and technologies advance, has the potential to yield new and illuminating information on brain activity and connectivity. Critical information about the promise and limitations of this technology is explored in a forward-looking review article in the groundbreaking new neuroscience journal Brain Connectivity, a bimonthly peer-reviewed journal published by Mary Ann...

Groundbreaking Brain Scanner Reconstructs Visual Experiences
2011-09-23 05:13:47

   Scientists at the University of California, Berkeley, have created a groundbreaking brain-imaging process that allows them to 'see' moving images inside people's minds.  The researchers had volunteers watch movie clips as a scanner watched their brains. Then, using this brain activity, a computer made a rough reconstruction of what the study participants viewed. As the test subjects thought of a video, the scientists were able to 'see' it on screen, the researchers...

Machine's magnetic field pushes fluid in the inner ear's balance organ A team of researchers says it has discovered why so many people undergoing magnetic resonance imaging (MRI), especially in newer high-strength machines, get vertigo, or the dizzy sensation of free-falling, while inside or when coming out of the tunnel-like machine. In a new study published in Current Biology online on Sept. 22, a team led by Johns Hopkins scientists suggests that MRI's strong magnet pushes on fluid...

UC Berkeley researchers decode and reconstruct dynamic visual experiences, in this case Hollywood movie trailers Imagine tapping into the mind of a coma patient, or watching one's own dream on YouTube. With a cutting-edge blend of brain imaging and computer simulation, scientists at the University of California, Berkeley, are bringing these futuristic scenarios within reach. Using functional Magnetic Resonance Imaging (fMRI) and computational models, UC Berkeley researchers have...

Research conducted by Boston College neuroscientist Sean MacEvoy and colleague Russell Epstein of the University of Pennsylvania finds evidence of a new way of considering how the brain processes and recognizes a person´s surroundings, according to a paper published in the latest issue of Nature Neuroscience. For the study, MacEvoy and Epstein used functional magnetic resonance image (fMRI) to help them identify how the brain figures out where it is in the world (scene recognition)....

Twenty years after the publication of the first human study using functional magnetic resonance imaging (fMRI)* - a technique to measure activity in the brain through the flow of blood - the Wellcome Trust has published a report providing reflections on the field of human functional brain imaging. The Wellcome Trust report assesses the key developments in human functional brain imaging and examines the role it has played as a funder. Supporting neuroscience research has been a cornerstone...
