WebFeb 2, 2024 · While they have the common features of a typical cell, they are structurally and functionally unique from other cells in many ways. All neurons have three main parts: 1) dendrites , 2) cell body or soma, and 3) axons. Besides the three major parts, there is the presence of axon terminal and synapse at the end of the neuron. WebAug 24, 2024 · Introduction. Cortical axons transmit neuronal information quickly and efficiently over long distances. The advent of axonal recording techniques identified the distal portion of the axon initial segment (AIS, ∼20–40 μm from the soma) as the main initiation site of most cortical action potentials (Kole et al. 2007; Shu et al. 2007; Hu et al.
