Illiterate adults who have learned to read and write over half a year show brain changes – even in regions not obviously linked to reading, writing or learning Via iPamba, Miloš Bajčetić

Using optogenetics, researchers at the UC Davis Center for Neuroscience and Department of Psychology have used light to erase specific memories in mice, and proved a basic theory of how different parts of the brain work together to retrieve episodic memories. Optogenetics, pioneered by Karl Diesseroth at Stanford University, is a new technique for manipulating and studying nerve cells using light. The techniques of optogenetics are rapidly becoming the standard method for investigating brain function.

Researchers develop new technology which allows for more accurate mapping of the connections within white matter tissue in the human brain.
Roughly 100 trillion connections between neurons make it possible for the brain to function. Psychology Professor Brian Wandell’s group has devised a technique for mapping these connections with greater accuracy than ever before.
Two different algorithms produce two very different estimates of the shape of the same white matter connection in Franco Pestilli’s brain. The LiFE software, developed in the Wandell Lab, aims to produce more precise estimates. Credit Wandell Lab. Via iPamba, Miloš Bajčetić

When you learn a new technical concept, something happens in your brain, but exactly what has been a mystery until now.
Summary from Learning and the Brain Society Newsletter - April 2015 Teaching science to the brain: How the brain learns the way things work
For the first time, Carnegie Mellon University scientists have traced the brain processes that occur during the learning of technical concepts. Published in NeuroImage, researchers, scanned the brains of 16 healthy adults as they learned for the first time how four common mechanical systems work. While inside the brain scanner, the participants were shown a series of pictures, diagrams and text that described the internal workings of a bathroom scale, fire extinguisher, automobile braking system and trumpet. The explanation sequence allowed the researchers to examine the participants' brain states after each learning step. The findings reveal how new technical knowledge is built up in the brain during the course of different learning stages and foreshadow the capability to assess the effectiveness of instruction and efficiency of learning by monitoring changes in the brain. Robert Mason lead author explains "This provides evidence that appropriate instruction can bring out the fundamental understanding of how things work at a deep level. In the future, teaching to this deep level as measured in terms of brain representations may be applicable to other disciplines and scientific concepts." Via iPamba, Miloš Bajčetić

Magnetic stimulation of a brain area involved in "executive function" affects cravings for and consumption of calorie-dense snack foods, reports a study in the September issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
After stimulation of the dorsolateral prefrontal cortex (DLPFC), young women experience increased cravings for high-calorie snacks—and eat more of those foods when given the opportunity, according to the study by researchers at University of Waterloo, Ont., Canada. "These findings shed a light on the role of the DLPFC in food cravings (specifically reward anticipation), the consumption of appealing high caloric foods, and the relation between self-control and food consumption," the researchers write. The senior author was Peter Hall, PhD. Via iPamba, Miloš Bajčetić
