(page 277 ), What are the functions performed by the three types of neurons? What does it mean to say a local potential is graded, decremental, and reversible? . Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area. Neurons are born in areas of the brain that are rich in concentrations of neural precursor cells (also called neural stem cells). What are their functions? The science of stem cells is still very new, and could change with additional discoveries, but researchers have learned enough to be able to describe how neural stem cells generate the other cells of the brain. WebA neural circuit is formed by interconnecting of many neurons and are impotant for functiong of the nervous system .There are 4 types of neural circuits based on the type of the connections. 2 ) sensory neuron - enough stimulation = action potential generated in sensory neuron But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brains communication system. Importance. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season.
