Electrical Properties of Dendrites Help Explain the Brain’s Unique Computing Power
Human dendrites have different electrical properties from those of other species, a new study reveals. Researchers report electrical signals weaken more as they flow along human dendrites, allowing small sections of dendrites to behave independently from the rest of the neuron.
