Touch is bound to the skin - that is, to the boundaries of the body. Yet, the activity of neurons in primary somatosensory cortex just mirrors the spatial distribution of the sensors across the skin. To determine the location of a tactile stimulus on the body, the body's spatial layout must be considered. Moreover, to relate touch to the external world, body posture has to be evaluated. In this...

What is the word for sense of signals that come from inside your body, such as feeling heart beating and breathing, or knowing when you are hungry? This called interoception. Interoception one our senses, like vision, hearing, taste, smell, touch. In this article, we talk about what interoception how information these feelings sent body to brain. We will also a little measured different types F...

Touch differs from other exteroceptive senses in that the body itself forms part of the tactile percept. Interactions between proprioception and touch provide a powerful way to investigate the implicit body representation underlying touch. Here, we demonstrate that an intrinsic primary quality of a tactile object, for example its size, is directly affected by the perceived size of the body part...

There are anatomical and functional links between auditory somatosensory processing. We suggest that these form the basis for popular internet phenomenon where people enjoy a sense of touch from (and often audiovisual) stimuli.

The sense of touch is imperative in cognition, development, and for how we perceive the world and interact with others. The skin envelopes our body and is our largest organ providing us with information about our immediate environment. In addition to this “surface” information, our somatosensory system also processes information regarding body position and internal bodily states. The importance...

Smoking has devastating and often fatal effects on human health. It a wide range of harmful the body, even organs like liver that don't come into direct touch with smoke. On liver, it causes three primary harms: toxic (both indirect), immunological effects, oncogenic consequences. The cytotoxic potential chemicals produced by smoking might contribute to cell damage. purpose this research was pr...

Reproducing the capabilities of human sense touch in machines is an important step enabling robot manipulation to have ease dexterity. A combination robotic technologies will be needed, including soft robotics, biomimetics and high-resolution sensing offered by optical tactile sensors. This considered here as a SoftBOT (Soft Biomimetic Optical Tactile) sensor. article reviews BRL TacTip prototy...

Action requires knowledge of our body location in space. Here we asked if interactions with the external world prior to a reaching action influence how visual location information is used. We investigated if the temporal synchrony between viewing and feeling touch modulates the integration of visual and proprioceptive body location information for action. We manipulated the synchrony between vi...

The mec-5 and mec-9 genes encode putative extracellular proteins that allow a set of six touch receptor neurons in C. elegans to respond to gentle touch. MEC-5 is a collagen made by the epidermal cells that surround the touch cells. Mutations causing touch insensitivity affect the Gly-X-Y repeats of this collagen. mec-9 produces two transcripts, the larger of which is expressed in the touch cel...
