Example sentences for: hyperpolarization

How can you use “hyperpolarization” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In our experiments, the chloride influx and membrane hyperpolarization associated with 4-AP treatment not only decreased expression of StAR, but also inhibited cAMP production and steroidogenesis.

  • PMA induces hyperpolarization of rat β-cells

  • The magnitude of the hyperpolarization depended on the concentration of PMA (Fig.

  • Data obtained previously in our laboratory suggest that inhibition of granulosa I Kur should be associated with a +10 to +20 mV depolarization of cell resting membrane potential; block of I Ks alone decreased resting potential by +10 mV while block of both I Ks and I Kur decreased resting potential by +20 to +30 mV [ 18 ] . Most previous investigations of 4-AP effects on the resting membrane potentials of non-nerve, non-muscle cells have similarly demonstrated drug-induced depolarization [ 42 60 ] , although there is a single report showing 4-AP-induced hyperpolarization of chondrocyte membrane potential [ 62 ] .

  • 3), it is obvious that the hyperpolarization caused by PMA results from activation of this channel type, and PMA inhibition of glucose-induced electrical excitation of rat β-cells is ascribable at least in part to hyperpolarization resulting from an increase in K ATP activity.
