When we speak, although we may not be aware of it, we use our auditory and somatosensory systems to monitor the results of the movements of our tongue or lips.

An important function of vision is to segregate relevant figures from the irrelevant background. A visual stimulus drives a cascade of neural activity from low-level to higher level visual brain areas. The higher areas also ...

We can generally recognize an object, even if it is presented for a very brief time. However, if another object appears immediately following the first object, the perception on the first object is impaired such that we do ...

Being constantly flooded by a mass of stimuli, it is impossible for us to react to all of them. The same holds true for a little fish. Which stimuli should it pay attention to and which not? Scientists at the Max Planck Institute ...

Visual feedback is just as important as a sense of body position when it comes to the involuntary reflexes that activate muscle movement, says a new study in the open-access journal eLife.

Georgetown University neuroscientists say they have identified how people can have a "crash in visual processing"—a bottleneck of feedforward and feedback signals that can cause us not to be consciously aware of stimuli ...

For decades, the neuroscience community has been baffled by the existence of dense connections in the brain that seem to be going "backwards." These connections, which span extensively across distant areas of the neocortex, ...
