Neurons: Neurons are the cells that make up our nervous system, including the brain, spinal cord, and peripheral nerves. Neurons are usually classified as afferent neurons, those that send messages to the brain, and efferent neurons, those receiving messages from the brain. Sensory neurons are ...
There are five major senses that the body uses to detect stimuli. These include touch, smell, taste, sight, and hearing. The sense of touch produces different feelings depending on what is being touched. This is detected by sensory nerves....
However, among the cells that can be damaged by diabetes, the primary sensory neurons, also known as dorsal root ganglion (DRG) neurons, are uniquely sensitive. Damage to these cells results in diabetic peripheral neuropathy (DPN), one of the costliest and most common diabetic complications. ...
Sensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor,sensationhas occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages,...
Artificial neurons are modeled after the hierarchical arrangement of neurons in biological sensory systems. In the visual system, for example, light input passes through neurons in successive layers of the retina before being passed to neurons in the thalamus of the brain and then on to neurons in...

Single-cell RNAseq reveals seven classes of colonic sensory neuron. Gut 68, 633–644 (2018). This study identifies seven subtypes of sensory neurons innervating the colon of mice using single-cell RNA sequencing, therefore providing the molecular signature of specific neurons projecting to the ...
such as cytokines, prostaglandins or ATP, and interacting directly with nociceptors (sensory neurons that respond to potentially damaging stimuli) to cause pain if the pain threshold is reached. Pain sensation is transmitted through fast-conducting myelinated neurons (the fast neural pathway) (Fig.2...
