Image 1 - So That's What Dreams Are Made Of
2011-10-28 10:54:01

Scientists measure dream content for the first time and find that dreams activate the brain in a similar way to real actions. The ability to dream is a fascinating aspect of the human mind. However, how the images and emotions that we experience so intensively when we dream form in our heads remains a mystery. Up to now it has not been possible to measure dream content. Max Planck scientists working with colleagues from the Charité hospital in Berlin have now succeeded, for...

Haxby found that the brain's responses to movies reveal a detailed code that is the same for all individuals A team of neuroscientists at Dartmouth College has shown that different individuals' brains use the same, common neural code to recognize complex visual images. The paper, "A common, high-dimensional model of the neural representational space in human ventral temporal cortex," is in the October 20, 2011, issue of the journal, Neuron. The lead author of the paper is James Haxby,...

-A low level of response (LR) to alcohol reflects at least in part a low brain response to alcohol and carries significant risk for the later development of alcoholism. -This study used functional magnetic resonance imaging (fMRI) to examine brain activation in individuals with low and high LRs to alcohol while they performed a cognitive task. -Significant differences detected in brain activation may contribute to the inability by individuals with a low LR to recognize modest levels of...

(Ivanhoe Newswire) — Some people always view everything with the glass half full. Even if you´re a fan of the Browns and they keep losing, you still think that next week will be the week that they´ll turn it all around. So why, in the face of obvious evidence suggesting the contrary, do some people remain so optimistic about the future? According to researchers at the Wellcome Trust Centre for Neuroimaging at UCL (University College London) people who are very optimistic...

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?
2011-10-03 05:31:50

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...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
