Sentences with phrase «signal between neurons»

These systems are made up of complex algorithms modeled on the transmission of signals between neurons in the brain.
The result is a robust signal between neurons and within the larger communication network, which protects memory formation.
Specifically, it is important for the ion pumps that control signaling between the neurons of the brain.
In the absence of that protein, other proteins involved in transmitting signals between neurons in the brain are overproduced, notably mGluR5, a receptor for the neurotransmitter glutamate.
Receptors facilitate chemical and electrical signals between neurons in the brain, allowing those neurons to communicate with each other.
The illness is believed to result from impaired signaling between neurons in the brain caused by a reduction in myelin.
Dopamine, a molecule crucial for signaling between neurons, can not cross this barrier, which is why its chemical precursor, L - dopa, is used instead to treat Parkinson's disease.
For example, the scientists identified a deletion in one gene called «stargazin» that is required for regulating the transmission of signals between neurons in the brain.
Electrical signals between neurons generate electric fields that radiate out of brain tissue as electrical waves that can be picked up by electrodes touching a person's scalp.
Parkinson's disease is caused by the death of neurons in the brain that produce dopamine, a chemical that shuttles signals between neurons and is responsible for controlling the body's movement.
Dopamine is a so - called messenger substance or neurotransmitter that conveys signals between neurons.
The discovery that two forms of LTP exist in the ACC, with pre-LTP associated with anxiety and post-LTP associated with pain, explains why these two conditions are linked, as both conditions result in an increase in transmission of the glutamate signal between neurons in the ACC.
But that is probably not the only route through which neuregulin - 1 confers its benefits, and the group is exploring other possible mechanisms — such as whether the protein improves signaling between neurons, which is impaired in Alzheimer's — says the study's first author Jiqing Xu, a research associate in Lee's group.
One idea is that they reproduce the behaviour of synapses, the conducting gaps that ferry electronic signals between neurons.
The neurotransmitters act as batons in a relay, transferring signals between neurons in the brain and throughout the body.
The most abundant neurotransmitters within the brain are amino acids and they are responsible for the majority of fast signalling between neurons.
One of the key indicators of Alzheimer's disease are the protein amyloid plaques that form and prevent electrical and chemical signaling between neurons.
It's also important to note that endorphins are neurotransmitters, which means that they have the ability to send signals between neurons.
Neurotransmitters are basically chemical messengers responsible for carrying, boosting and modulating signals between neurons.
These drugs inhibit the reabsorption of serotonin, making it available longer for transmitting signals between neurons.
Neurodevelopmental disorders such as intellectual disability and autism spectrum disorders are marked by mutations that impair signaling between neurons.
Researchers from Princeton University and the University of California - San Diego (UCSD) recently found that an immune - system protein called MHCI, or major histocompatibility complex class I, moonlights in the nervous system to help regulate the number of synapses, which transmit chemical and electrical signals between neurons.
When it's not misfolded, α - synuclein is believed to carry out functions related to the transmission of signals between neurons.
According to William Jagust, a neuroscientist at the University of California, Berkeley, adults are also losing dopamine, a critical neurotransmitter (the type of chemical involved in transmitting signals between neurons), at the rate of 5 to 8 percent per decade.
Pape is currently analyzing her data to determine if the FAST intervention strengthened the brain's wiring, the elongated fibers called axons that transmit signals between neurons.
Scientists used to believe that neurotransmitters, chemicals that signal between neurons, were released in random bursts.
«So we tested the signaling between different neurons in fragile X mice, and indeed found there was abnormally high firing of action potentials — the signals between neurons — and also abnormally high synchrony; that is, too many neurons fired together.
This was found to interfere with the same mechanism, essentially by impairing the ability of alpha - synuclein to regulate the flow of synaptic vesicles, and hence compromising the signalling between neurons.
VDACs are present in all neurons, especially the sodium and potassium channels along the axons, which play a fundamental role in the generation of action potential and signaling between neurons.
