Imagine that you are driving to work along an icy road when a deer suddenly jumps into your path. Depending on the distance, you may have time to apply the brakes, or you may consider swerving to avoid a collision. Your intuitive ability to reason about the physics of objects in your environment, for instance… Read more

A laser-assisted imaging tool was used by Johns Hopkins Medicine researchers to observe what happens in brain cells of mice learning to reach out and grab a pellet of food. Their experiments, they say, add to evidence that such motor-based learning can occur in multiple areas of the brain, even ones not typically associated with… Read more

The conscious perception of visual location occurs in the frontal lobes of the brain, rather than in the visual system in the back of the brain, according to a study from Dartmouth College. The results are significant given the ongoing debate among neuroscientists on what consciousness is and where it happens in the brain. “Our… Read more

In decades of studying how neural circuits in the brain’s visual cortex adapt to experience, MIT Professor Mark Bear’s lab has followed the science wherever it has led. The journey yielded the discovery of cellular mechanisms serving visual recognition memory, in which the brain learns what sights are familiar so it can focus on what’s… Read more

Researchers at the Salk Institute report the discovery of three cell types in the eye that detect light and align the brain’s circadian rhythm to our ambient light. The study[1] marks the first direct assessment in humans of light responses from these cells, called intrinsically photosensitive retinal ganglion cells (ipRGCs), and the implications for health… Read more
