Not exact matches

The research team discovered leptin and insulin interact with proopiomelanocortin (POMC) neurons in the brain's hypothalamus, causing them to send signals through the nervous system promoting the conversion of white fat into brown fat.

With the Human Brain Project, researchers will use supercomputers to reproduce how brains form — basically, growing them in an virtual vat — then seeing how they respond to input signals from simulated senses and nervous system.

Sophisticated neuroimaging machines and brain - computer interfaces detect the electrical activity of neurons, enabling us to decode and even alter the nervous system signals that accompany mental processes.

Axons, the long projections of neural cells which form the nerves of our peripheral nervous system, are like electrical cables: they have thick electrical insulation so that they can quickly relay stimuli from the body and signals from the brain to a toe, for example.

The retina sits at the back of the human eye, and contains protein cells that convert light into electrical signals that travel through the nervous system, triggering a response from the brain, ultimately building a picture of the scene being viewed.

In the course of this work, he has pioneered several new approaches in the fruit fly that have had important implications for mammalian neurobiology, including: the demonstration that the fruit fly has a sleep - like behavior similar to that of mammals, studies of physiological and behavioral consequences of mutations in a neurotransmitter system affecting one of the brain's principal chemical signals, studies making highly localized genetic alterations in the nervous system to alter behavior, and molecular identification of genes causing naturally occurring variation in behavior.

It means recording the signals that the brain is trying to send via the spinal cord, translating them into an electrical stimulus pattern that the nervous system understands, and then providing that pattern of electrical stimulation at some point below the level of the injury.

Their crisscrossing paths and collective efforts have nonetheless led to a clear - eyed understanding of how neurons — the brain's cellular building blocks — form and function and how ion - conducting channels control the flow of electrical signals through the nervous system.

Neuropeptides comprise a large class of signaling molecules which are secreted from neurons and transmit messages within the brain and across the nervous system.

Garrison is interested in a large class of signaling molecules called neuropeptides which are secreted from neurons and transmit messages within the brain and across the nervous system.

Finally, the strategy applied here for selective delivery of MK801 can be extended to other small molecules for use in brain tissue (Tian et al., 2012), allowing for an approach that combines chemistry, molecular genetics, and neurobiology to dissect cell signaling pathways in specific cell types in the central nervous system.

Most painkillers (or analgesics, from the Greek term for the absence of pain) work on the central nervous system — the brain and the spinal cord — and the peripheral nervous system, which connects the rest of the body to them, sending signals back and forth.

The cell membranes within the brain, spinal cord, & nervous system are especially dependent upon fluid based membranes for proper signaling and neurotransmitter dynamics (2).

It is found in the brain and spinal cord and is associated with inflammatory processes and pain — it acts as a neurotransmitter to carry pain signals to the nervous system.

These «afferent signals», or signals that flow to the brain, have a regulatory influence on many aspects of your nervous system, including most of your glands and organs.

These neurotransmitters are the signals that carry thoughts, feelings, and commands around our brains and throughout our nervous system.

The basic sensations of hunger, pain and satiety are examples of signals that require efficient bidirectional communication between the enteric nervous system and the brain.

The enteric nervous system is responsible for initiating the rhythmic peristaltic movement of the gut, as well as relaying important signals to and from the brain.

If you've ever come back after lunch and felt tired, nauseous, or a little «fuzzy,» your enteric nervous system may be reacting to something you ate — and sending signals to your brain.

The term «microbiota - gut - brain axis» is used to describe the complex bidirectional signaling that occurs between the GI tract and the nervous system, and emphasizes the newly recognized role of intestinal microbes in these interactions.

These processes are facilitated by the instantaneous delivery of electrical signals that are transmitted, via the peripheral nervous system, from tissues throughout a cat's entire body to its spinal cord and brain.

These injuries disrupt the signals that are carried back and forth between the body and the brain, which comprises the central nervous system (CNS).
