Mapping the Brain’s Sensory Gatekeeper

Mapping the thalamic reticular nucleus, researchers have identified two distinct subnetworks of neurons with different functions. Findings offer insight into more specific targets for therapeutics to alleviate some sensory, sleep, and attention symptoms associated with ASD and other disorders characterized by sensory hypersensitivity.

Feeling with the Heart

The brain suppresses the perception of the heartbeat, affecting our perception of other sensory stimuli. Researchers propose the brain's sensitivity to sensory stimuli depends on the cardiac cycle and the brain's perception of it. Read More

How expectations influence learning

Our brains make predictions based on experience during episodes of learning. Researchers found expectations during the predictions affect the activity of various brain networks. Read More

Why those on the autism spectrum are often hypersensitive to light and noise

Mice lacking the autism-associated SHANK3 gene were more sensitive to sensation, including touch. The mice also had overactive excitatory neurons in the somatosensory cortex, which may account for sensory hypersensitivity. Read More

Electronic glove offers ‘humanlike’ features for prosthetic hand users

Researchers have developed a sensor-instrumented glove for prosthetic hand controls which can sense pressure, temperature, and hydration using electronic chips sending sensory data via a wristwatch. Read More

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

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

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
