Some types of neurons have no axon and transmit signals from their dendrites.

Some neurons in the posterior parietal cortex are modulated by intention.

Some neurons emit action potentials constantly, at rates of 10 – 100 per second, usually in irregular patterns ; other neurons are quiet most of the time, but occasionally emit a burst of action potentials.

Some regenerated nerve fibers do not find the correct muscle fibers and some damaged motor neurons of the peripheral nervous system ( PNS ) die without re-growth.

Some neurons also contain pigment granules, such as neuromelanin ( a brownish-black pigment, byproduct of synthesis of catecholamines ) and lipofuscin ( yellowish-brown pigment that accumulates with age ).

Some neurons are typically constantly ( or tonically ) active.

Some neurons also communicate via electrical synapses, which are direct, electrically-conductive junctions between cells.

Some neurons do not generate action potentials, but instead generate a graded electrical signal, which in turn causes graded neurotransmitter release.

Some neurons do, however, communicate via electrical synapses through the use of gap junctions, which allow specific ions to pass directly from one cell to another.

Some places of noted degradation include the median raphe nuclei, the noradrenergic parts of the locus coeruleus, and the cholinergic neurons in the parabrachial and pedunculopontine nuclei of the tegmentum.

Some early studies reported substantial loss of neurons in the hippocampus of elderly people, but later studies using more precise techniques found only minimal differences.

Some landmarks of neural development include the birth and differentiation of neurons from stem cell precursors, the migration of immature neurons from their birthplaces in the embryo to their final positions, outgrowth of axons and dendrites from neurons, guidance of the motile growth cone through the embryo towards postsynaptic partners, the generation of synapses between these axons and their postsynaptic partners, and finally the lifelong changes in synapses, which are thought to underlie learning and memory.

Some cells or organelles have the same membrane potential throughout ; neurons generally have different potentials at different points.

Some researchers theorize mammalian intelligence correlates to the number of nerve cells ( neurons ) in the cortex of the brain.

Some investigators, like developmental psychologist Andrew Meltzoff and neuroscientist Jean Decety, believe that mirror neurons merely facilitate learning through imitation and may provide a precursor to the development of ToM.

Some glial cells function primarily as the physical support for neurons.

Some neurons are responsible for conveying information over long distances.

# Some of the branches of the I-a axons synapse directly with alpha motor neurons. These carry impulses back to the same muscle causing it to contract.

Some other inputs come from the brainstem, including from some of the noradrenergic neurons of the nucleus of the solitary tract and the ventrolateral medulla.

Some prefrontal cortex neurons represented actual and some — perceived displacements of the stimulus.

Some of these neurons responded differently to light patterns than to dark patterns.

Some of us might be inclined to argue, in fact, that an independence of mind and action and an intolerance of regimentation, either mental or physical, are particularly Southern traits.

Some years ago Julian Huxley proposed to an audience made up of members of the British Association for the Advancement of Science that `` man's supernormal or extra-sensory faculties are ( now ) in the same case as were his mathematical faculties during the ice age ''.

Some are fishing, some driving the team, and many are sitting indolently on the banks of the river.

Some historians have found his point of view not to their taste, others have complained that he makes the Tory tradition appear `` contemptible rather than intelligible '', while a sympathetic critic has remarked that the `` intricate interplay of social dynamics and political activity of which, at times, politicians are the ignorant marionettes is not a field for the exercise of his talents ''.

Some of the marble busts in the park are of young Englishmen who fought and died for Garibaldi.

Some accounts are quite lengthy but Florida's is the shortest of all, requiring only four paragraphs.

Some plant-location specialists take these signs to mean St. Louis county doesn't want industry, and so they avoid the area, and more jobs are lost.

Some fiscal changes are important.

Some brilliant rookies nailed them down, so that this spring just two spots, left and right field, are really up for grabs.

Some of the stumps are as much as three feet long, but most of them have been flattened by the pressure of the overlying sediments.

Some privately held inholdings are a source of direct damage to these Federal lands.

Some 45 frequencies are assigned for use primarily by dominant Class 1, -- A or Class 1, -- B clear-channel stations, designed to operate with adequate power and to provide service -- both groundwave and ( at night ) skywave -- over large areas and at great distances, being protected against interference to the degree necessary to achieve this objective.

Some deductions are subtracted from Gross Income to determine Adjusted Gross Income.

Some renditions are of symphonic dimensions, with the contrabass given free rein.

Some of them are obvious, such as the fact that we associate recorded and live music with our responses and behavior in different types of environments and social settings.

Some tasty frank toppings are chili con carne, Coney Island sauce and savory sauerkraut.

Some general things to look for in a site, if you haven't already bought one, are accessibility, water drainage, and orientation.

Some distribution costs are kept up by competitive pressure, some by the fact that the customers have come to expect certain niceties and flourishes.

Some of these temperatures are plotted in figure 4.

( Some suspensions break up before they are near to the direction of shear, and some become asymptotic to it without breakup.

Some experiments are composed of repetitions of independent trials, each with two possible outcomes.

Some of these speculations may have some merit, others are somewhat ambiguous.

Some phonetic features, for example glottal catch or murmur, are sometimes to be assigned to segmental phonemics and sometimes to accentual systems.

Some are failing to achieve as much as their ability would permit ; ;
