Scientists solve long-standing mystery by a whisker
When we step on the car brake upon seeing a red traffic light ahead, a sequence of events unfolds in the brain at lightning speed.

Real neurons are noisy. Can neural implants figure that out?
If human eyes came in a package, it would have to be labeled "Natural product. Some variation may occur." Because the million-plus retinal ganglion cells that send signals to the human brain for interpretation don't all perform ...

Scientists map how human retinal cells relay information to brain
To understand how we see the world and how diseases such as age-related macular degeneration and glaucoma impair vision, scientists need to understand how the retina communicates vision signals to the brain.

Protein-transport discovery may help define new strategies for treating eye disease
Many forms of vision loss stem from a common source: impaired communication between the eye and the brain. And at the root of all eye-to-brain communication are the hundreds of proteins generated by the retina's nerve cells.

New study shows how autism can be measured through a non-verbal marker
A Dartmouth-led research team has identified a non-verbal, neural marker of autism. This marker shows that individuals with autism are slower to dampen neural activity in response to visual signals in the brain. This first-of-its ...

Research suggests revision to common view on how retinal cells in mammals process light
Johns Hopkins Medicine scientists say that new experiments with mouse eye tissues strongly suggest that a longstanding "textbook concept" about the way a mammal's retina processes light needs a rewrite.

Researchers map early visual processing between the retina and the brain
How are the images cast on the retina reassembled in the brain? Researchers in Munich and Tuebingen find that processing of visual stimuli occurs at the earliest waystation on the way to the visual cortex—but not all inputs ...

We need to fine-tune our 'maps' of the visual cortex, study shows
Monkey brain scans have revealed new information about the brain structure that processes visual information. The findings were recently presented in PNAS by neurophysiologists Qi Qhu (KU Leuven) and Wim Vanduffel (KU Leuven/ ...

Optimized perception in the twilight zone
In the pre-industrial age, twilight was a dangerous time for humans due to higher risk of encountering nocturnal predators. The ability to see in weak light conditions was therefore at a clear evolutionary advantage. Neuroscientists ...

Neuroscientists identify brain circuit that integrates head motion with visual signals
Neuroscientists at the Sainsbury Wellcome Centre have identified a circuit in the primary visual cortex (V1) of the brain that integrates head- and visual-motion signals. The study, published today in Neuron, elucidates the ...
