The paired-pulse ratio ppr
WebbT h e ratios between the weights of the seed- lings grown for any specific period (e.g., 9, 90 ,180 days) were the same as the ratios of the seed weight classes from which the plants were grown. A n adjustment factor can be derived to correct the dry weights of the seedlings grown from any seed weight class to a "normal" value (Aldrich-Blake, 1930, … Webb10 maj 2024 · Additionally, we review how PNN removal affects plasticity-associated phenomena such as long-term potentiation (LTP), long-term depression (LTD), and paired-pulse ratio (PPR). The results are discussed in the context of the role of PV interneurons in circuit function and how PNN removal alters this function.
