Controlling individual cortical nerve cells by human thought
Science Daily Thu, 28 Oct 2010 06:07 AM PDT
Five years ago, neuroscientists and neurosurgeons discovered that a single neuron can function much like a sophisticated computer and recognize people, landmarks, and objects. Now the same researchers have found that individuals can exert conscious control over these single neurons -- despite the neurons' location in an area of the brain previously thought inaccessible to conscious control ... |
Mind over matter: Study shows we consciously exert control over individual neurons
EurekAlert! Thu, 28 Oct 2010 06:01 AM PDT
A collaboration between UCLA scientists and colleagues from the California Institute of Technology has shown that humans can actually regulate the activity of specific neurons in the brain, increasing the firing rate of some while decreasing the rate of others. And study subjects were able to do so by manipulating an image on a computer screen using only their thoughts. |

Tumor Suppressor Acts As Oncogene In Some Cancers
Medical News Today Thu, 28 Oct 2010 05:32 AM PDT
Researchers at Mayo Clinic in Florida have found that a molecule long believed to be a beneficial tumor suppressor and thus a potential cancer drug target appears to act as an oncogene in some lethal brain tumors. The protein, epithelial cadherin (E-cadherin), is known for its ability to keep cancer cells glued together, preventing them from breaking away and metastasizing. But, based on their ... |
New Insight Into Links Between Obesity And Activity In The Brain
Medical News Today Thu, 28 Oct 2010 03:30 AM PDT
Scientists have revealed that an anti-obesity drug changes the way the brain responds to appetising, high-calorie foods in obese individuals. This insight may aid the development of new anti-obesity drugs which reduce the activity in the regions of the brain stimulated by the sight of tasty foods. Researchers at the University of Cambridge discovered that the anti-obesity drug sibutramine ... |
