Our brains have about a hundred billion [[neuron]]s that fire signals to communicate with each other all the time. These signals are electrochemical in nature, and travel from the cell body of a neuron through its transport stalk or the [[axon]], to the next neuron – similar to passing the baton in a relay race. Every such firing signal is referred to as a [[spike]], or an [[action potential]]. Spikes are produced in response to stimuli or spontaneously, and each spike typically lasts for 1 millisecond. Neurons produce action potentials that are referred to as '[[spike]]s' in laboratory jargon. Frequently this term is used for electrical signals recorded in the vicinity of individual neurons with a microelectrode (exception: 'spikes' in EEG recordings) ---- [[Signal intensity]] ---- see [[Cell signaling]]. see [[Neural signal]]. see [[Signal transducer]]. see [[MR signal]] signal.txt Last modified: 2024/06/07 02:48by 127.0.0.1
