WebFeedforward inhibition improves the temporal precision of many types of neurons by hyperpolarizing the membrane potential shortly after the onset of excitation, thereby narrowing the window for suprathreshold summation of excitatory inputs (Cobb et al., 1995; Pouille and Scanziani, 2001; Ingham and McAlpine, 2005; …. WebApr 25, 2024 · While feedforward inhibition is expected to increase with excitation, convergence of I/E ratios for randomly chosen inputs to a cell to a single number was unexpected, since shared interneurons consist of only about 10% of the total neuronal population (Woodson et al., 1989; Bezaire and Soltesz, 2013). itf taekwondo facebook norwayWebSep 5, 2024 · The gate control theory proposes that Aβ mechanoreceptor inputs to spinal pain transmission T neurons are gated via feedforward inhibition, but it remains unclear how monosynaptic excitation is gated by disynaptic inhibitory inputs that arrive later.
