How does the prefrontal cortex contribute to executive functions?

Dec 4, 2017 ... We propose that these intracellular pathways are potential therapeutic targets for achieving depolarization/hyperpolarization (D/H) balance in psychiatric and ... Frydman is particularly enthusiastic about is nuclear hyperpolarization [4, 5]. ... hyperpolarization had been known about for 60 years, and for the first 40 of ... Hyperpolarization is a lowered membrane potential caused by the efflux of potassium ions and closing of the potassium channels. Resting state is when ... Plasma membrane hyperpolarization can lead to calcium influx.18 Therefore, we tested the effects of ivermectin on calcium influx in leukemia cells. OCI-AML2 ... Potassium ions reach equilibrium when the membrane voltage is below −70 mV, so a period of hyperpolarization occurs while the K+ channels are open. movement of a cell's membrane potential to a more negative value (i.e., movement further away from zero). When a neuron is hyperpolarized, it is less likely to ... Hyperpolarized fumarate is a promising biosensor for carbon-13 magnetic resonance metabolic imaging. Such molecular imaging applications require nuclear ... Hyperpolarized 13 C magnetic resonance spectroscopic (MRS) imaging has emerged as a complementary metabolic imaging approach. 4 days ago ... 2 meanings: British → a variant spelling of hyperpolarize biology, physics to cause increased polarization.... Click for more definitions. Apr 4, 2022 ... Apparently the sodium potassium pump restores it following hyperpolarization, but I really can't imagine how it would do that!
