19.12.2012 How the Brain Categorizes Thousands of Objects and Actions
Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings.
18.12.2012 MRIs Reveal Signs of Brain Injuries Not Seen in CT Scans
Hospital MRIs may be better at predicting long-term outcomes for people with mild traumatic brain injuries than CT scans, the standard technique for evaluating such injuries in the emergency room, according to a clinical trial led by researchers at the University of California, San Francisco (UCSF) and the San Francisco General Hospital and Trauma Center (SFGH)
18.12.2012 How We Update Our Goals Based On New Information
Humans are adept at setting goals and updating them as new situations arise - for example, a person who is playing a video game may switch to a new goal when their phone rings.
12.12.2012 Advanced Brain Investigations Can Become Better and Cheaper
An important method for brain research and diagnosis is magnetoencephalography (MEG). But the MEG systems are so expensive that not all EU countries have one today. A group of Swedish researchers are now showing that MEG can be performed with technology that is significantly cheaper than that which is used today-technology that can furthermore provide new knowledge about the brain
03.12.2012 Unprecedented Accuracy in Locating Brain Electrical Activity With New Device
Researchers at Aalto University in Finland have developed the world's first device designed for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain. The merging of these two technologies will produce unprecedented accuracy in locating brain electrical activity non-invasively
20.11.2012 Two Steps During LTP Remodel Internal Skeleton Of Dendritic Spines
Neuroscience researchers have discovered how a structural component within neurons performs coordinated movements when connections are strengthened. Researchers also distinguished two separate steps during long term potentiation which are involved in remodeling the internal “skeletons” of dendritic spines
06.11.2012 Loneliness? It’s All a State of Mind
Researchers from UCL have found that lonely people have less grey matter in a part of the brain associated with decoding eye gaze and other social cues
19.10.2012 How the Brain Forms Categories
Neurobiologists investigated how the brain is able to group external stimuli into stable categories
10.10.2012 S1 long-term plasticity
S1 long-term plasticity refers to persistent modifications in the structure or functioning of the primary somatosensory cortex
10.10.2012 Frontal eye field
The Frontal Eye Field is a region of primate prefrontal cortex defined as the area in which low-current electrical stimulation evokes saccadic eye movements
07.10.2012 Researchers Create a Universal Map of Vision in the Human Brain
The researchers combined traditional fMRI measures of brain activity from 25 people with normal vision. They then identified a precise statistical relationship between the structure of the folds of the brain and the representation of the visual world.

18.09.2012 Music Underlies Language Acquisition
Contrary to the prevailing theories that music and language are cognitively separate or that music is a byproduct of language, theorists at Rice University’s Shepherd School of Music and the University of Maryland, College Park advocate that music underlies the ability to acquire language
