Sentences with phrase «detected by a neuron»

The compound is detected by a neuron which expresses the olfactory receptor Or47b; this receptor responds exclusively to methyl laurate.

Then the researchers doused dengue - spreading mosquitoes with a chemical that shuts down the mosquitoes» ability to detect CO2 by blocking a receptor called neuron — cpA, a type of sensory cell found on a small pair of antennalike structures near the mouth called the maxillary palps.

When a neuron sends a message it releases the neurotransmitter serotonin, which is detected by the next neuron receiving the message.

The researchers also identified the specific neuron responsible for detecting high pH. They did this by showing that when a specific sensing neuron, called the ASH neuron, was destroyed by laser microsurgery, the worms no longer avoided high pH. Going another step further, the researchers also identified some of the proteins involved in the response to high alkalinity, which make up a calcium channel.

It is no good having a technology that tells you that a neuron has fired by giving off a flash of light, if you can not detect that light.

«By engineering mice that have these mutations only in their peripheral sensory neurons, which detect light touch stimuli acting on the skin, we've shown that mutations there are both necessary and sufficient for creating mice with an abnormal hypersensitivity to touch.»

Scientists aren't sure if the neurons are triggered by the death of hair cells (which detect normal level sound as part of hearing) or simply dangerous sound levels.

These neurons are separate from the ones that detect pain, and yet, chemical - induced itch is often accompanied by mild pain such as burning and stinging sensations.

The scientists discovered that a class of mechanoreceptors in the skin that detect painful mechanical stimuli are part of a feedback circuit in which excitatory neurons that produce the hormone somatostatin are inhibited by neurons that synthesize dynorphin (a natural analgesic molecule that produces effects similar to opiates).

Research conducted by Dr Bill Dew at the University of Lethbridge in Canada looked for the first time at the effect of the metal contaminants nickel and copper on specific fish olfactory sensory neurons, and how these affect the fish's ability to detect and swim away from an odour released by other fish of the same species (conspecifics) when a predator attack takes place.

Methyl laurate is also detected by another sensory neuron type that expresses the olfactory receptor Or88a.

Further, the researchers found that MMP - 9 can be detected not just in lumbar 5 neurons, but also in other types of motor neurons affected by ALS.

Thus, by monitoring the activity of motion - detecting neurons in animals and simultaneously exploring human motion perception using cunningly contrived displays such as a, b and c, scientists are starting to understand the mechanisms in your brain that are specialized for seeing motion.

A specific kind of neuron found only in male mice and that detects a pheromone in female urine has been identified by researchers at Washington University School of Medicine in St. Louis.

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.

By detecting the waves, the scanner can reconstruct the brain as well as detect where neurons are consuming oxygen — a sign of mental activity.

A team led by Anandasarkar Ray at the University of California, Riverside, identified an important class of neurons in mosquitoes that detect our skin odors.

Neurons were detected using the pan neuronal marker TuJI (red) and the synaptic contact by alpha - Bungarotoxin (green).

The present study revealed a consistent subcellular segregation of immunoreactive sites detected by Aβ - specific antibodies and pab27576 within neurons of different brain areas, at pre - and post-plaque stages of the amyloid pathology.

The researchers have shown that a robotic arm guided by a cell - detecting computer algorithm can identify and record from neurons in the living mouse brain with better accuracy and speed than a human experimenter.

We've been able to bridge those findings to human studies, developing ways to both look for those neurons in the retina, see whether or not they're sick using imaging techniques that Alf and Vivek have developed, and clinical tests along with Jeff Goldberg in order to detect whether or not patients are losing an excessive amount of those kinds of neurons by virtue of different types of field testing.

These cues are detected via olfactory (OR), trace - amine associated (TAAR), vomeronasal (VR) and formyl - peptide (FPR) receptors expressed by the sensory neurons in the epithelia of these organs.

It also suggests that in unc - 9 mutants, the native UNC - 7 isoforms expressed in motor neurons (as detected by previous analysis of total UNC - 7 expression) are insufficient to properly localize AVB - expressed UNC - 7S:: GFP (that is, UNC - 7 in motor neurons does not substitute for UNC - 9 in localizing AVB - expressed UNC - 7S).

This is coupled by ghrelin activity, which is also detected by Hypocretin Neurons.
