WebDendrite self-avoidance produces a uniform distribution of branches within the neuron’s territory through competitive interactions among dendrites emanating from the same neuron, or “self” dendrites (Fig. 12.7).This process ensures efficient sampling of inputs by a given neuron. Otherwise, neurons receive fewer synapses and expend resources on dendrites … Webreflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus.
