Neuron
Definition:
(n.) The brain and spinal cord; the cerebro-spinal axis; myelencephalon.
Example Sentences:
(1) Therefore, these findings may extend the use of platelets as neuronal models.
(2) Although solely nociresponsive neurons are clearly likely to fill a role in the processing and signalling of pain in the conscious central nervous system, the way in which such useful specificity could be conveyed by multireceptive neurons is difficult to appreciate.
(3) On the other hand, after exposure to BrdUrd, neuron specific enolase decreased in NB-1 and SK-N-DZ and increased in GOTO.
(4) The present findings indicate that the deafferented [or isolated] hypothalamus remains neuronally isolated from the environment if the operation is carried out later than the end of the first week of life.
(5) This modulation results from repetitive, alternating bursts of excitatory and inhibitory postsynaptic potentials, which are caused at least in part by synaptic feedback to the command neurons from identified classes of neurons in the feeding network.
(6) However, the firing of 5-HT neurons appears to relate to the state of vigilance of the animal.
(7) As prolongation of the action potential by TEA facilitates preferentially the hormone release evoked by low (ineffective) frequencies, it is suggested that a frequency-dependent broadening of action potentials which reportedly occurs on neurosecretory neurones may play an important role in the frequency-dependent facilitation of hormone release from the rat neurohypophysis.
(8) Two small populations of GLY + neurons were observed outside of the named nuclei of the SOC; one was located dorsal to the LSO, near its dorsal hilus, and the other was identified near the medial pole of the LSO.
(9) Based on our results, we propose the following hypotheses for the neurochemical mechanisms of motion sickness: (1) the histaminergic neuron system is involved in the signs and symptoms of motion sickness, including vomiting; (2) the acetylcholinergic neuron system is involved in the processes of habituation to motion sickness, including neural store mechanisms; and (3) the catecholaminergic neuron system in the brain stem is not related to the development of motion sickness.
