A flex sensor or bend sensor is a sensor that measures the amount of deflection or bending. Usually, the sensor is stuck to the surface, and resistance of sensor element is varied by bending the surface. Since the resistance is directly proportional to the amount of bend it is used as goniometer, and often called flexible potentiometer.
Stimulus modality, also called sensory modality, is one aspect of a stimulus or what is perceived after a stimulus. For example, the temperature modality is registered after heat or cold stimulate a receptor. Some sensory modalities include: light, sound, temperature, taste, pressure, and smell. The type and location of the sensory receptor ...
In physiology, a stimulus[1] is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [2] Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in the eye, as ...
Four types of sensory neuron. Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal ...
Schematics and images of types of limb proprioceptor neurons in mammals (top) and insects (bottom) [1] Proprioception (/ ˌproʊpri.oʊˈsɛpʃən, - ə -/ [2][3] PROH-pree-oh-SEP-shən, -ə-) is the sense of self-movement, force, and body position. [1][4] Proprioception is mediated by proprioceptors, sensory receptors, located within ...
Optogenetics. Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of ...
Mechanoreceptor. A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system.
Perception (from Latin perceptio 'gathering, receiving') is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. [2] All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation ...
