New studies help to explain how microbes in the gut can shape a host’s fear responses.
Activity in the visual cortex and other sensory areas is dominated by signals about body movements, down to little tics and twitches. Scientists are now rethinking how they study and conceive of perception.
Singing experiments with residents of the Bolivian rainforest demonstrate how biology and experience shape the way we hear music.
While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.
Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.
