Inhibitory and excitatory inputs
WebbThis suggests that excitatory inputs from the BLA to cortical GABAergic interneurons follow the same short-term dynamics as those from thalamic and cortical sources. … Webb14 juli 2024 · Neurons communicate through electrical currents called action potentials, which are either excitatory or inhibitory. Excitatory currents are those that prompt one neuron to share information with the next through an action potential, while inhibitory currents reduce the probability that such a transfer will take place.
