The ability to perceive and discriminate diverse types of sensation is reflected by the existence of specialized dorsal root ganglion (DRG) sensory neurons tuned to respond to specific stimuli.

Despite much research on pain receptors, investigators have only recently focused on itch and how the body distinguishes between itch and pain. This research show that the receptors responding to ...

The type and intensity of stimuli control the activity of nerve cells that release the neurotransmitter dopamine, report scientists. Regardless of whether we are sitting in a loud aeroplane or walking ...

While olfaction and hearing have distinct sensory pathways and primary processing areas, they ultimately converge within ...

When we feel pain in response to harmful stimuli it is the result of messages sent from pain sensors in the periphery of the body to the brain. These pain sensors – or nociceptors – often lie beneath ...

Behavioral responses to painful stimuli require peripheral sensory neurons called nociceptors. Electrophysiological studies show that most C-fiber nociceptors are polymodal (i.e., respond to multiple ...

American scientists David Julius and Ardem Patapoutian were awarded the 2021 Nobel Prize in Medicine for their “discoveries of receptors for temperature and touch,” a breakthrough that, according to ...

Sensory overload is the overstimulation of one or more of the body’s five senses. People will respond differently to feeling overstimulated, but symptoms often include anxiety, discomfort, and fear.

Brittany Dube is a public health professional with expertise in health education and community health. She works for her local Department of Health as a Behavioral Health, Health Promotion, and ...

Opioids slot into opioid receptors and activate them. This sends signals to your brain to relieve pain and promote pleasure. Both endogenous opioids, which your body naturally produces, and exogenous ...
