The structure and function of the nervous system
A bundle of neurones is called a nerve. There are three main types of neurone: sensory, motor and relay. They have some features in common: A long fibre (axon) which is insulated by a fatty ...
MIT engineers turn skin cells directly into neurons for cell therapy
MIT researchers devised a process to convert a skin cell directly into a neuron, eliminating the need to generate induced pluripotent stem cells. Such neurons could be used to treat spinal cord ...
