Sensory information enters the brain at the primary sensory cortex, where they are processed by different layers of cells in ways that ultimately influence an animal's perception and behavioral ...

Mechanoreceptors in human skin can sense the delicate weight of a butterfly, feel the heat of a nearby flame or a cool drink, understand whether a hand is raised in a fist or a peace sign, and count ...

A new study by UT Health San Antonio and Stanford University scientists brings us closer to understanding how the body detects different sensations such as pain, itch and touch. When a person feels ...

Sensory processing disorders are conditions that affect how the brain processes sensory information. They can cause over or undersensitivity to sensory information, including sight, sound, and touch.

Although motor control involves many pathways and circuits in the spinal cord and brain, Fink and colleagues' study focused on the simplest: the feedback between muscle sensory afferent neurons (which ...

PITTSFIELD — We all have our likes and dislikes. The food we eat. The clothes we wear. The places and situations we find either comfortable or somehow awkward, even scary or upsetting. For most of us, ...

The neocortex comprises the largest part of the cerebral cortex and is the outermost layer that covers the structures of the brain. Comprised of four main lobes with specific functions, the cortex ...

The “wires” that carry electrical signals among nerve cells in the brain can influence the threshold at which the cells will send those signals, research on mouse-brain tissue shows. The finding ...

Sensory overload is the overstimulation of one or more of the body’s five senses. People will respond differently to feeling overstimulated, but symptoms often include anxiety, discomfort, and fear.

CUTANEOUS mast cells in the rat differ from those of other species in that they contain, besides histamine, 5-hydroxytryptamine (5-HT) 1. It is known that in the cat 5-HT excites certain cutaneous ...
