How does the degree of hyperpolarization affect the interspike interval?

Jul 5, 2024 ... How to accelerate the acquisition speed and obtain liver images with high spatial resolution: The hyperpolarization level of 13C probe is ... 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 ... The crucial point of hyperpolarization is to transfer the polarization from highly polarized systems to nuclear spins. For example, the unpaired electrons in ... Jan 26, 2023 ... Hyperpolarization techniques are able to enhance signal intensities in magnetic resonance by several orders of magnitude, and thus to largely overcome its ... 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. Sep 4, 2012 ... That is, hyperpolarization is an increase in the absolute value of a cell's membrane potential. Thus, any change of membrane voltage in which ... Perhaps even more surprising is that shining light on a photoreceptor, either a rod or a cone, leads to membrane hyperpolarization rather than depolarization ( ... The two general methods of hyperpolarization are dynamic nuclear polarization (DNP) and parahydrogen induced polarization (PHIP). experiments with CIDNP hyperpolarization. This setup has been described in detail in Ref. [52]. Two series of experiments were carried out: measurements of ...
