Mechanisms behind hornworm self-defense discussed at the 2023 American Physiology Summit

Graduate student Christian Valtierra presented research conducted in Dr. Megumi Fuse’s lab (San Francisco State University) at the 2023 American Physiology Summit last month. The research was focused on examining the defensive strike response in Manduca sexta hornworms. Animals respond to potentially damaging stimuli with the help of sensory neurons, called nociceptors, that specialize in detecting these stimuli. In humans, activation of these receptors is what causes us to perceive […]

Are humans really just upright cats?

Okay seriously, humans are not actually cats. But, humans and cats do share similar nervous system control over how we move from one place to another, i.e. locomotion as described in a recent review article published in Physiology. The ability for mammals to finely control movement depends on two main control systems located in the brain and spine as well as sensory feedback from the skin, muscles, tendons, eyes, and […]
