Post-Synaptic Potentials and Action Potentials: Membrane Potentialsormation takes place at a neuron’s axon hillock and initial segment, and conduction of the integrated signal occurs down its axon. And at the hundreds of terminals formed by its axon, a neuron transmits information to its targets. This division of labor among the several parts of a neuron is referre

Adult Neurogenesis Rodents and primates have two neurogenic zones, the hippocampus and the olfactory bulb. Lower vertebrates often have many more sites of adult neurogenesis. In the peripheral nervous system, there is high neurogenesis in the olfactory epithelium. Neurogenesis in the olfactory bulb originates from pr

Axonal Guidance: Making Connectionshese circuits during brain development, neurons extend an axon from the cell body to make connections with neurons in target brain areas, which can be a considerable distance away from the neuronal cell body. To ensure that axons accurately elongate toward the correct target field over such a distan

Axonal Transportnces, up to a meter or more in large animals. Remarkably, however, most axonal components originate in the nerve cell body, at one end of the axon, and must be shipped out along the axon by mechanisms of intracellular motility. In addition, signals from the axon and its environment must be conveyed
