WebThe answer lies in how often action potentials are sent – the action potential frequency. When the brain gets really excited, it fires off a lot of signals. How quickly these signals fire tells us how strong the original stimulus is - the stronger the signal, the higher the frequency of action potentials. red flags a guy is a playerWebApr 12, 2024 · Early-firing neurons are more excitable and have prominent spike frequency adaptation, while late-firing neurons are less excitable and maintain a tonic firing pattern at low... red flags abdominal pain niceWebApr 14, 2024 · It is common to distinguish between two types of excitability in neurons: Type I excitability, where the neuron can fire with arbitrarily low firing frequency close to the threshold current, and Type II, where firing increases abruptly from zero to a non-zero value when the threshold is reached.
