Internuncial
Definition:
(a.) Of or pertaining to an internuncio.
(a.) Communicating or transmitting impressions between different parts of the body; -- said of the nervous system.

(19) This strongly suggests that the caudate nucleus interneuronal apparatus is dominated by centre-median input, in contrast to the putamen which is controlled by the cortico-striatal input to its internuncial cells and by its strong intrastriatal feedback mechanism.
(20) The activity of afferent and internuncial neurons of the bulbar cardiovascular centre (BCVC) was evaluated, using microelectrodes, in conditions of serotonin microinjections, altered blood gas composition and sensomotor cortical stimulation, in acute experiments in cats and rabbits.
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.
(10) Thus, it appears that neuronal loss may account for up to roughly half of the striatal D2 receptor loss during aging.
(11) This report is an overview of the data and has incorporated some additional findings of the influence of the ACTH4-9 analog, Org2766, on neuronal excitation, especially in the hippocampus.
(12) The results are consistent with our previous suggestion that lethality for virulent SFV infection results from a lethal threshold of damage to neurons in the CNS and that attenuating mutations may reduce neuronal damage below this threshold level.
(13) We conclude that the rat somatosympathetic reflex consists of an early excitatory component due to the early activation of RVL-spinal sympathoexcitatory neurons with rapidly conducting axons and a later peak that may arise from the late activation of these same neurons as well as the early activation of RVL vasomotor neurons with more slowly conducting spinal axons.
(14) We conclude that neuronal activities in the region of the retrofacial nucleus are important both in the integration of stimuli from the central chemoreceptors and in defining the discharge patterns of respiratory neurons.
