Transduction


Definition:

  • (n.) The act of conveying over.

Example Sentences:

  • (1) Preservation of dopaminergic and H1 neurotransmission, probably within the blood barrier, is needed to allow the neuroendocrine transduction of cholinergic inputs, whereas the role of 5-HT neurotransmission remains uncertain.

  • (3) Additionally, the amount of mRNAs for preproenkephalin as well as for the cellular proto-oncogenes c-myc, c-fos and c-H-ras, which are thought to be mediators of intracellular signal transduction, was determined in hippocampus in these same animals.
  • (4) Our results suggest that multiple receptors and signal transduction pathways are involved in the regulation of the tyrosine hydroxylase gene in the rat adrenal medulla.
  • (5) This report examines the timing of changes in the contractile potential of the cortical cytoplasm as the oocyte becomes the egg, and in addition, the signal transduction events which induce these changes.
  • (6) A possible role of the olfactory tubercle in olfactory transduction will also be discussed.
  • (7) Meta II is the form of photolyzed rhodopsin which binds and activates the visual G-protein (Gt); thus, its relative abundance at equilibrium and temporal stability are important parameters in determining the efficiency of visual signal transduction.
