The brain’s imperfect execution of mathematically optimal perception
Perception is founded on Bayesian principles, even though the brain's execution of strategies appears to be imperfect. Researchers say the view perception is an imperfect Bayesian inference can provide a middle ground between traditional and anti-Bayesian models.... Read More...
Scientists Create a Model for the Neural Basis of Expectation
A new theoretical model helps explain how the gustatory cortex mediates the expectation of receiving a taste. The model sheds light on the neural basis of expectation.... Read More...
Associating colors with vowels? Almost all of us do!
While only 1 in 25 people has synesthesia, a new study reports intuitions about 'sound colors' are shared by a greater percentage of people. Sound color perception is mainly driven by the vowels in language.... Read More...
People ‘hear’ flashes due to disinhibited flow of signals around the brain
The synesthesia effect of being able to 'hear' silent movements may depend upon disinhibition of signaling between the visual and auditory brain regions. The study found musicians are more likely to experience the 'visual ear' phenomena than those with no musical training.... Read More...
New Prosthetic Restores the Sense of Where Your Hand Is
A new prosthetic hand enables amputees to regain a subtle, close to natural, sense of touch.... Read More...
How the Brain Responds to Texture
A new study reports neurons in the somatosensory cortex respond differently to various features of a surface, creating a high dimensional representation of texture in the brain. The findings could help develop neuroprosthetics capable of identifying textures in greater detail.... Read More...
How Our Brains Distinguish Between Self Touch and the Touch of Others
A new neuroimaging study reveals brain activity is reduced when we experience self touch, as opposed to the touch of another person. The findings shed light on how the brain is able to distinguish between tactile sensations generated by the touch of another and personal touch.... Read More...
How the Brain Enables Us to Rapidly Focus Attention
Researchers have identified a mechanism within the cholinergic system that underlies our ability to rapidly focus attention.... Read More...
Touch Can Produce Detailed, Lasting Memories
According to a new study, exploring objects through touch can generate detailed, lasting memories of the object, even when people don't intend to memorize the details of the object. ... Read More...
Philosophy of the Mind: In Touch with Reality
According to a new study, we trust our fingertips over our eye when it comes to processing ambiguous information.... Read More...
