Sentences with phrase «received by neurons»

«The correct functioning of the nervous system depends on a very well - regulated balance between excitatory and inhibitory inputs received by the neurons.

Neuronal activity typically requires sensory input — for example, a taste or smell — that gets received by neurons» dendrites and then transmitted as an electrochemical message to other cells via long axons.

Not exact matches

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

What's more, by controlling the timing of an electrical stimulus, Malenka and UCSF researchers conclusively demonstrated that they could cause more AMPA receptors to appear on the outer membrane of a receiving neuron — or, conversely, to disappear.

AMPA receptors are activated by the excitatory neurotransmitter glutamate and are important to both how spines are shaped and how well neurons receive incoming signals for action.

Neurons release neurotransmitters that are taken up by specific receptors, but many glial cells receive and emit neurotransmitters that float through the brain as free agents.

A research team led by Oliver Schlüter (University of Pittsburgh, PA, USA) found that cocaine - induced place preference in mice — returning to places where the drug was previously received — does not depend on lasting rewiring of neurons in the NAc.

It is due to these proteins that the information arriving at a synapse can be transmitted and then received by the next neuron.

Blue corresponds to cell nuclei, and green to fluorescence emitted by a green - fluorescent protein that identifies neurons having received the virus that can genetically abolish the expression of lipoprotein lipase protein.

One is the «spine pruning theory,» supported by the observation that the frontal brain regions of people with schizophrenia have fewer dendritic spines, the tentacles on the receiving ends of neurons that process signals from other cells.

Astrocytes also form their own long - distance communication networks by «talking» via waves of calcium ions, and, like neurons, they can receive and release neurotransmitters.

By 1963 his condition had gotten bad enough that his mother brought him to a hospital in London, where he received the devastating diagnosis: motor neuron disease, as ALS is called in the United Kingdom.

Neurons, or nerve cells, in the brain communicate with each other by transmitting electric signals, or firing action potentials, through long processes named axons (which send out signals) and dendrites (which receive signals).

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

The second team, led by Patrik Brundin of the Wallenberg Neuroscience Center in Lund, Sweden, found Lewy bodies in grafted neurons from two patients, who each received two grafts between 11 and 16 years before their deaths.

The new study by researchers at The Neuro shifts the focus to the loss or degeneration of axons, the nerve - cell «branches» that receive and distribute neurochemical signals among neurons.

In these tests, Gütig explained, «a neuron received a continuous stream of sensory clues represented by different input patterns.

A synapse has three components: a pre-synaptic terminal contributed by the sending neuron, a post-synaptic receptive component contributed by the receiving cell and a synaptic cleft — the space between the pre - and post-synaptic components.

A new study authored by Marc Schieber, M.D., Ph.D., and Kevin Mazurek, Ph.D. with the University of Rochester Medical Center Department of Neurology and the Del Monte Institute for Neuroscience, which appears in the journal Neuron, shows that very low levels of electrical stimulation delivered directly to an area of the brain responsible for motor function can instruct an appropriate response or action, essentially replacing the signals we would normally receive from the parts of the brain that process what we hear, see, and feel.

The neurons, isolated from rats, produce bursts of electrical signals in various patterns, which can be â $ œtunedâ $ by the inputs they receive.

He is currently funded (2016 - 2021) by the National Cancer Institute to study radiation induced changes in neuron cell dendritic morphology in cancer treatment with X-rays, protons and carbon beams, and has received grants from the Department of Energy and NASA in the past.

Neurons communicate with each other through chemical signals that are released from one nerve terminal (pre-synapse) and received by another (post-synapse).

It means that Hypocretin Neurons are instead always acted upon by mostly uniform — excitatory — signals they receive.
