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.
