We all have heard about 'tennis elbow' but now scientist have found another thing, known as "cell phone elbow." Surprised? Well, Cell Phone Elbow or Cubital Tunnel Syndrome (CTS) results from constantly holding a cell phone to the ear which can cause severe nerve damage. This is the price most people will have to pay to 'get connected all the time'.

According to the U.S. Bureau of Labor Statistics, Cubital Tunnel Syndrome or Cell Phone Elbow is one of the most common motion disorder which hits more than 85o,000 people every year. Physicians are saying that they are seeing more patients with CTS every day.

Priya, 16 year old girl, used to speak on her cell phone several hours each day, but recently she was having trouble holding her cell phone to her ear. Every time she held cell phone to her ear for more then three minutes she has shooting pain in her elbow and numbing of fingers. According to doctors, bending the elbow for extended periods puts pressure on the ulnar nerve and the only option was to move the nerve and release pressure through surgery. To undergo surgery was kind of a shock to Priya.

Washington : Boffins have identified two classes of brain cells with distinct roles in visual attention, and highlighted mechanisms by which these cells mediate attention in a manner that allows us to fix our gaze on one object while independently directing attention to others.

Researchers led by Jude Mitchell, at the Salk Institute conducted experiments on primates who learned to play sophisticated video game, which challenged their visual attention-focusing skills.

The study recorded electrical activity from almost 200 different neurons in part of the visual cortex that has been implicated in mediating visual attention, and examined how each neuron’s response changed when attention was directed to the stimulus in its receptive field.

Researchers found that the neurons responded when a stimulus appeared within a window known as the neuron’s ‘receptive field, which covers a small part of the visual field that the eye sees.
