More than one-third of respondents reported predominantly negative feelings, such as frustration. The researchers identified that envying their "Facebook friends" is the major reason for this result. Project manager Dr. Hanna Krasnova, who is currently a post-doctoral researcher at the Humboldt-Universität, explained that, "Although respondents were reluctant to admit feeling envious while on Facebook, they often presumed that envy can be the cause behind the frustration of "others" on this platform - a clear indication that envy is a salient phenomenon in the Facebook context. http://medicalxpress.com/news/2013-01-facebook-users-envious-dissatisfied.html Psychology & Psychiatry Mon, 21 Jan 2013 08:34:38 EST news277979662 (Medical Xpress)—The classic theory of the brain is one of connections, in which the brain consists of a network of neurons that interact with each other to allow us to think, see, interpret, and understand the world around us.

For example, a certain pattern of many neurons fires when you think "dog" and another pattern for "cat." http://medicalxpress.com/news/2012-12-brain-cells.html Neuroscience Tue, 04 Dec 2012 08:30:07 EST news273783154
