Just a quick survey: Which is better? I haven't found anyone who thinks he looks better on the right except, interestingly, the patient himself at one point in time. At a glance we can see buff health on the left, thin and sickness on the right.
I posted this because, leafing through a fitness magazine during a brief wait this evening, I noticed a woman "fitness model" who was anything but. Her height and weight were listed as 5'7" and 112 pounds, but the numbers were superfluous. Here was a gal modeling exercise who veered  dangerously toward a feminine version of the image on the left.... not a desirable outcome for hours in the gym and sensible eating. A little muscle looks good on everyone, and regardless of the number on the scale, malnutrition in the form of anorexia (or obesity) is bad news for body, soul, and mind.

From Neuroscience Stuff on Tumblr:
Coming soon: a brain implant to restore memory
In the next few months, highly secretive US military researchers say they will unveil new advances toward developing a brain implant that could one day restore a wounded soldier’s memory.
The Defense Advanced Research Projects Agency (DARPA) is forging ahead with a four-year plan to build a sophisticated memory stimulator, as part of President Barack Obama’s $100 million initiative to better understand the human brain.
The science has never been done before, and raises ethical questions about whether the human mind should be manipulated in the name of staving off war injuries or managing the aging brain.

Brain Gains #987: Work at a pleasant temperature!

 Reblogged from neurosciencestuff                                                                                                                                                                               
Better memory at ideal temperature
People’s working memory functions better if they are working in an ambient temperature where they feel most comfortable. That is what Leiden psychologists Lorenza Colzato and Roberta Sellaro conclude after having conducted research. They are publishing their findings in Psychological Research.
Studied for the first time
Everyone knows from experience that climate and temperature influence how you feel. But what about our ability to think? Does ambient temperature affect that too? The little research that has been done on this question shows that cooler environments promote cognitive performance when performing complex thinking tasks. Colzato and Sellaro are the first to investigate whether a person’s working memory works better when the ambient temperature perfectly matches his or her preference.
N-back test
To study the influence ambient temperature has on cognitive skills, Colzato and Sellaro performed tests on two groups of participants. One group had a preference for a cool environment, the other group preferred a warm one. The test subjects had to carry out thinking tasks in three different spaces. In the first the temperature was 25 degrees Celsius (77 Fahrenheit), in the second it was 15 degrees (59 Fahrenheit), and in the third the thermostat was set to 20 (68 Fahrenheit). The thinking task that the subjects had to perform was the so-called N-back task. Different letters would appear one after the other on the computer screen. Subjects had to indicate whether the letter that they saw was the same as the one they had seen two steps earlier.

Idea confirmed
Test subjects proved to perform better in a room with their preferred temperature. The conjecture is that working in one’s preferred temperature counteracts ‘ego depletion’: sources of energy necessary to be able to carry out mental tasks get used up less quickly. ‘The results confirm the idea that temperature influences cognitive ability. Working in one’s ideal temperature can promote efficiency and productivity,’ according to Colzato and Sellaro.

Brain Gains: #988: Chocolate!

Several studies have demonstrated an inverse association between chocolate consumption and stroke, at least in men. The case is especially convincing for dark chocolate, so enjoy some chocolate!
