While popularly publicized neuroscience research focuses on structural and functional connectomes, timing patterns of axonal spikes, neural plasticity, and other areas of inquiry, the intraneuronal environment also receives ...
The ability to construct complex myelin sheaths around axons is one of the greatest vertebrate inventions since the hinged jaw.
