These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

These channels regulate membrane excitability, and halothane has been found to reduce neuronal firing by hyperpolarizing neurons by a current similar to TASK.

These questions include how signals are processed by neurites – thin extensions from a neuronal cell body, consisting of dendrites ( specialized to receive synaptic inputs from other neurons ) and axons ( specialized to conduct nerve impulses called action potentials ) – and somas ( the cell bodies of the neurons containing the nucleus ), and how neurotransmitters and electrical signals are used to process information in a neuron.

These questions include the patterning and regionalization of the nervous system, neural stem cells, differentiation of neurons and glia, neuronal migration, axonal and dendritic development, trophic interactions, and synapse formation.

These impulses are extremely fast, with some myelinated neurons conducting at speeds up to 120 m / s.

These receptors, which exist in a variety of areas in the body, inhibit firing of neurons that would otherwise be stimulated to do so by nociceptors.

These neurons release the excitatory neurotransmitter glutamate at their synapses.

These include sensory neurons that transmute physical stimuli such as light and sound into neural signals, and motor neurons that transmute neural signals into activation of muscles or glands ; however in many species the great majority of neurons receive all of their input from other neurons and send their output to other neurons.

These first order neurons enter the spinal cord via Lissauer's tract.

These second order neurons ( spinothalamic tract ) then decussate, crossing via the anterior white commissure before ascending contralaterally.

The first studies of the electrophysiological properties of neurons in MT showed that a large portion of the cells were tuned to the speed and direction of moving visual stimuli These results suggested that MT played a significant role in the processing of visual motion.

These findings have also been confirmed by stereotactic microelectrode analysis of single cortical neurons in a study, which involved nine patients undergoing bilateral cingulotomy.

These results combined with electrophysiological investigation of the function of neurons in the anterior cingulate cortex have provided insights that can be used in the improvement of cingulotomy performed on patients treated for OCD.

These neurons use GABA as their neurotransmitter.

These constitute the great majority of neurons in the densely packed hippocampal layers.

These reflect subthreshold membrane potentials and strongly modulate the spiking of hippocampal neurons and synchronise across the hippocampus in a travelling wave pattern.

These proteins would then intervene the rapid upstroke of an action potential, thus allowing a flow of sodium ions into neurons.

These studies are quite exciting because they show that neurons that have suffered the consequences of loss of MECP2 function are poised to regain functionality once MECP2 is provided gradually and in the correct spatial distribution.

These findings have led to the hypotheses that ( 1 ) breakdown of the blood – brain barrier allows access of neuron-binding autoantibodies and soluble exogenous Aβ42 to brain neurons and ( 2 ) binding of these auto-antibodies to neurons triggers and / or facilitates the internalization and accumulation of cell surface-bound Aβ42 in vulnerable neurons through their natural tendency to clear surface-bound autoantibodies via endocytosis.

These proteins act to accelerate hydrolysis of GTP to GDP and terminate the transduced signal.

These prematurely terminate translation if the corresponding frame-shift ( such as due to a ribosomal RNA slip ) occurs before the hidden stop.

These lines terminate into a 33kV ( or 66kV ) substation, where the voltage is stepped-down to 11kV for power distribution to load points through a distribution network of lines at 11kV and lower.

These fibers terminate at the medulla oblongata.

These theorems, strictly speaking, prove that there is at least one non-spacelike geodesic that is only finitely extendible into the past but there are cases in which the conditions of these theorems obtain in such a way that all past-directed spacetime paths terminate at a singularity.

These epochs terminate respectively: ( 1 ) with the death of Gedaliah after the destruction of the Temple ; ( 2 ) with the death of Bar Kokba ( ca.

These run in a South-West / North-East direction, and terminate in East Perth in the south, whilst providing a service to Midland and Guildford in the north.

These bundles of axons are situated near the midline of the brainstem and are composed of both ascending and descending fibers that arise from a number of sources and terminate in different areas.

These include a special health plan, the Beihilfe, which covers 50 % of most health care expenses, the other part being the responsibility of the Beamter himself and usually being covered by buying private ensurance ; an index-linked pension of at most 71. 5 % of the last salary, paid directly by the state rather than by the usual public pension insurance ; and most importantly, the virtual impossibility of losing one's job-basically, the state may transfer Beamte who do not perform well to other, often less desirable, posts, but may only terminate employment entirely in cases of serious felonies.

These nanoshells are not metabolized so for them to be effective they just need to be within the tumor cells and photo-induced cell death ( as described above ) is used to terminate the tumor cells.

These standards of evidence ascend as follows: no credible evidence, some credible evidence, a preponderance of evidence, clear and convincing evidence, beyond reasonable doubt, and beyond any shadow of a doubt ( i. e. undoubtable — recognized as an impossible standard to meet — which serves only to terminate the list ).

These junctions terminate one road into another:

These fibers terminate in the last abdominal segment.

These roads begin / terminate in the area known as Vineland and Lake Buena Vista, Florida.

These clusters may terminate suddenly in either an upward or downward direction forming a stratographic layer.

These have wires which terminate in flat metal contacts, and they are connected to the circuit by sliding the contacts between the metal strips of two neighbouring blocks.

These latter two do not terminate here but instead continue on to France ( TAT-11 ) and England ( Gemini ).

These both terminate locally, at Carrcote and Denshaw, and also both run to Ashton, using similar routes.

These highways cut through the northern part of the region and terminate at Kumasi in the Ashanti Region.

These tapering walls, which act as visual markers to the park, eventually terminate at activity areas as seats.

These services either terminated at Lydney Town railway station, which was in the centre of Lydney, or continued on northwards into the Forest of Dean to terminate at Lydbrook Junction on the Ross to Monmouth line.

These terminate at Preston late in the evening.
