The use of a probe elicits a response based on the vibrations in the instrument rather than direct environmental information. [17] Tactual perception gives information regarding cutaneous stimuli (pressure, vibration, and temperature), kinaesthetic stimuli (limb movement), and proprioceptive stimuli (position of the body).

The postcentral gyrus is the location of the primary somatosensory area, the main sensory receptive area for the sense of touch. [5] Pain receptors are known as nociceptors. Two main types of nociceptors exist, A-fiber nociceptors and C-fiber nociceptors. A-fiber receptors are myelinated and conduct currents rapidly. They are mainly used to ...
Sound waves may be viewed using parabolic mirrors and objects that produce sound. [ 9 ] The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy ...
The visual system and the somatosensory system are active even during resting state fMRI Activation and response in the sensory nervous system. The sensory nervous system is a part of the nervous system responsible for processing sensory information.
Under these approximations, the dispersion equation for electromagnetic waves includes two free-space modes that can escape the plasma as radiation (radio waves). These are called the ordinary ( o {\displaystyle o} ) and extraordinary ( x {\displaystyle x} ) modes. [ 18 ]
In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate response.
In a two level system, the particles have only two available energy levels, separated by some energy difference: ΔΕ = E 2 − E 1 = hv, where ν is the frequency of the associated electromagnetic wave of the photon emitted and h is the Planck constant. Also note: E 2 > E 1. These two levels are the excited (upper) and ground (lower) states.
In the somatosensory system the sensory transduction mainly involves the conversion of the mechanical signal such as pressure, skin compression, stretch, vibration to electro-ionic impulses through the process of mechanotransduction. [10] It also includes the sensory transduction related to thermoception and nociception.
