Touch is the process by which specialized neurons sense tactile information from the skin and other organs and convey this information to the brain, where it is perceived as sensations such as pressure, temperature, vibration, and pain.
The sense of touch in perceiving the environment uses special sensory receptors in the skin called cutaneous receptors. They include mechanoreceptors such as tactile corpuscles that relay information about pressure and vibration; nociceptors, and thermoreceptors for temperature perception.
Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more.
The sense of touch is one of the central forms of perceptual experience. While it has often been overshadowed by vision in both philosophy and psychology, recent years have seen an increased interest in touch. Touch is thought to be one of the first senses to develop.
Touch consists of several distinct sensations communicated to the brain through specialized neurons, or nerve cells, in the skin. Pressure, temperature, light touch, vibration, pain and other...
Our touch, or tactile sense, is a sense that most people are reasonably familiar with. It is one of the five senses you would have been taught about in school. The touch sense responds to anything that touches the skin. The skin is a very clever organ. It responds to much more than touch.
Our sense of touch helps us to interact with the world around us. Learn more about the brain and what regions process touch in A Nervous Journey. Learn more about our five senses.
In this video, children will discover what each layer is meant for and what is the overall function of the sense of touch. If we touch something hot, receptors and nerve endings in our skin...
The sense of touch conveys important social information, helping strengthen bonds between people. If your friend grips your hand so hard it hurts, touch lets you know something is wrong or dangerous through the feeling of pain. Sensations begin as signals generated by touch receptors in your skin.
The sensory cortex is an area of the brain that processes information about touch and other senses. Scientists call the sort of nerve map that is in the sensory cortex a homunculus, or “little man.”
