A small patch of neurons in the brain can encode the movements of many body parts, report researchers in the laboratory of Caltech’s Richard Andersen. Understanding this neural code could help improve the lives of people with paralysis or with motor deficits from neurological diseases such as a stroke. The motor cortex, the region of… Read more

Manipulating sleep spindle oscillations at the right timing affects memory, scientists at the Korean Institute for Basic Science have shown for the first time. The researchers, in collaboration with the University of Tüebingen, enhanced or reduced mouse memorization skills by modulating specific synchronized brain waves during deep sleep. Have you ever tried to recall something… Read more

When you stare in puzzlement at an optical illusion, two distinct parts of the neocortex in your brain are hard at work: the primary visual cortex is receiving information on what your eyes see, and the surrounding higher order visual areas are trying to interpret that tricky amalgam of information. These two areas, though, are… Read more

We are only consciously aware of a small portion of the sights, sounds, and sensations we experience. Neuroscientists from Brown University show in a new study how the neocortex selectively samples from the flow of sensory information that might otherwise flood it. The conventional metaphor to describe the neocortex is that it is the brain’s… Read more

Padraic Monaghan, Lancaster University Sleep has profound importance in our lives, such that we spend a considerable proportion of our time engaging in it. Sleep enables the body, including the brain, to recover metabolically, but contemporary research has been moving to focus on the active rather than recuperative role that sleep has on our brain… Read more
