Study Shows Limits on Brains Ability to Perceive Multifeatured Objects

A new study sheds light on how the brain encodes objects with multiple features, a fundamental task for the perceptual system. Researchers suggest neurons that encode a certain feature, such as shape or color, fire in synchrony with neurons that encode other features of the same object.

The FMRI image shows regions of activation including primary visual cortex (V1, BA17), extrastriate visual cortex and lateral geniculate body.

Pioneering Research Helps to Unravel the Brain’s Vision Secrets

A new study has identified the two areas of the brain responsible for our perception of orientation and shape. Research found that the two neighbouring areas, known as human visual field maps, process the different types of visual information independently.

Researchers Clarify Process Controlling Night Vision

New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels.

Robots that Perceive the World Like Humans

Researchers attempt to improve robot behavior by means of perception models closer to those of humans. One of the experiments involves a robot simulation in which an agent has to discriminate between what we could call an acne pimple and a bite or lump on the skin.

Researchers Explore How the Brain Perceives Direction and Location

The Who asked “who are you?” but Dartmouth neurobiologist Jeffrey Taube “where are you?” and “where are you going?” Taube is not asking philosophical or theological questions. He is investigating nerve cells in the brain that function in establishing one’s location and direction.

Using the Eye as a Window into the Brain

An inexpensive, five-minute eye scan can accurately assess the amount of brain damage in people with the debilitating autoimmune disorder multiple sclerosis (MS), and offer clues about how quickly the disease is progressing.

Researchers Create a Universal Map of Vision in the Human Brain

Researchers create a map of vision in the brain based upon an individual's brain structure, even for people who cannot see. Their result can, among other things, guide efforts to restore vision using a neural prosthesis that stimulates the surface of the brain.

Autistic Adults Have Unreliable Neural Responses, Carnegie Mellon-Led Research Team Finds

Neuroscientists take the first step toward deciphering the connection between general brain function and emergent behavioral patterns in autism. Study shows that autistic adults have unreliable neural sensory responses to visual, auditory and somatosensory, or touch, stimuli.
