Web14 de set. de 2024 · Sensory neurons will react to physical stimuli like temperature, sound, touch and light. These neurons will send a signal back to the nervous system which tells the body what the surrounding physical environment is like. The signal will tell you to shiver if cold or sweat if hot, or shield your eyes if the light is bright. 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 …
