Default Mode Network May Contain A Universal Code For Aesthetics

Using functional magnetic resonance imaging (fMRI) to monitor subjects’ brain activity as they were shown images of art, architecture or natural landscapes, researchers have found that in the visual parts of the brain, different types of images led to very different patterns of activity, even across images all judged by subjects to be aesthetically pleasing[1]. […]

How The Brain Processes The External World Using Overlapping Visual Circuits

A new study from Salk Institute researchers demonstrates that there are neurons that respond selectively to particular combinations of color and shape. “New genetic sensors and imaging technologies have allowed us to more thoroughly test the link between visual circuits that process color and shape. These findings provide valuable insight about how visual circuits are […]

How Extraneous Neural Background Noise Interrupts Focused Attention

Scientists have long theorized that attention to a particular object can alter perception by amplifying certain neuronal activity and suppressing the activity of other neurons (brain “noise”). Now, researchers from the Salk Institute have confirmed this theory by showing how too much background noise from neurons can interrupt focused attention and cause the brain to […]

Incoming Signals From The Retina Selectively Processed By Visual Thalamus

Processing of visual stimuli occurs at the earliest waystation on the way to the visual cortex, but not all stimuli are treated equally, research from Ludwig-Maximilians-Universit√§t M√ľnchen has uncovered. In humans, the visual system collects up to 80% of all the sensory data received from the environment. In order to make sense of this deluge […]

Your Brain Operates Backwards To Retrieve Memories

When we remember a past event, the human brain reconstructs that experience in reverse order, according to a new study from the University of Birmingham. Understanding more precisely how the brain retrieves information could help us better assess the reliability of eye witness accounts, for example of crime scenes, where people often are able to […]
