Sentences with phrase «firing electrical signals»

In the approximately 30 seconds between a rat's last heartbeat and the point when its brain stopped producing signals, the team carefully recorded its neuronal oscillations, or the frequency with which brain cells were firing their electrical signals.

Once the nanoparticles squeezed through the barrier and the mouse was exposed to a weak magnetic field, the critter's brain responded by firing electrical signals.

In the early 2000s, when Tsao was a postdoctoral researcher at Harvard Medical School, she and electrophysiologist Winrich Freiwald showed that neurons in a monkey's face patches would fire electrical signals every time the animal saw pictures of a face.

Not exact matches

In 2011 researchers found that these waves of electricity cause neurons in the hippocampus, the main brain area involved with memory, to fire backward during sleep, sending an electrical signal from their axons to their own dendrites rather than to other cells.

When Sørensen used the hand to grasp an object, electrical signals from the pressure pads fired directly into his nerves, giving him a sense of touch.

When one neuron's signal is strong enough, it causes the neuron on the other side of the synapse to fire an electrical spike.

Electrical signals in a majority of amygdala neurons mirrored the animal's behavior — they fired more in response to the dangerous tone compared to the safe one.

Once a specific threshold is reached, an electrical signal travels down the axon — the nerve fibers within the neuron — and the neuron fires.

For this, electrical signals fire between neurons connected by «axons» — thread - like extensions of their outer surfaces which can be viewed as the «wire» in the electric circuit.

Electrical recordings of signals transmitted from the hippocampus suggested that the animals had developed place cells — cells that are believed to convey a sense of location — and that these cells were firing when an animal passed through a familiar place.

It involves genetically modifying neurons so they produce a light - sensitive protein, which makes them «fire», sending an electrical signal, when exposed to light.

Shenoy's lab pioneered the algorithms used to decode the complex volleys of electrical signals fired by nerve cells in the motor cortex, the brain's command center for movement, and convert them in real time into actions ordinarily executed by spinal cord and muscles.

When these photoreceptors detect light, they send a signal to specialized neurons in the retina called retinal ganglion cells, or RGCs, which then transmit visual information to the brain by firing electrical pulses along the optic nerve.

A subset of neurons will fire — that is, send electrical signals that convey information — when a person focuses their attention on the upper half of a scene, whereas a different subgroup activates when attention is transferred to the lower half.

Other neurons in the culture began to fire one by one as they received an electrical signal from one of their neighbors.

Stimulating excitatory cells with chemicals or electric pulses causes them to fire, or send electrical signals of their own to neighboring neurons.

Brain cells communicate with each other by firing off tiny chemical and electrical signals.

In 1994, as a postdoctoral researcher then at the Max Planck Institute for Medical Research in Heidelberg, Germany, he became the first scientist to «patch» two living neurons simultaneously — to apply microscopic pipettes to freshly harvested rat neurons to measure the electrical signals fired between them.

Standing will burn just shy of double the calories, but walking around the office will burn 3 — 5 times as many calories (as well as getting the electrical signals to your lower body firing again).
