Ans: The 3 types of neurons according to functions are sensory neurons, motor neurons, and interneurons. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system. Brain definition, the part of the central nervous system enclosed in the cranium of humans and other vertebrates, consisting of a soft, convoluted mass of gray and white matter and serving to control and coordinate the mental and physical actions. Neuroplasticity is the brains ability to create new neural pathways. The neuron is one of the most vital cells in the body.
