Neuron
Neurons are nerve cells. Response to stimulus is the function of Neurons.
Neurons are nerve cells that send messages all over your body to allow you to do everything from breathing to talking, eating, walking, and thinking. Until recently, most neuroscientists (scientists who study the brain) thought we were born with all the neurons we were ever going to have.
Santiago Ramón y Cajal was a “peasant genius” who won a Nobel prize. IN 1906 THE Nobel prize in physiology or medicine was shared by two scientists with irreconcilable views of the brain.
Based on two contributions; Golgi’s stain and Cajal’s histological studies. The neuron doctrine was named and popularized by Heinrich Wilhelm Gottfried von Waldeyer-Hartz , who coined the name neuron to refer to the nerve cell.

What are 3 types of neurons and their functions ?
The sensory neurons carry information from the sensory receptor cells present throughout the body to the brain.
The motor neurons transmit information from the brain to the muscles.
The interneurons transmit information between different neurons in the body.

NEUROENGINEERING:-
Neuroengineering comprises fundamental, experimental, computational, theoretical, and quantitative research aimed at understanding and augmenting brain function in health and disease across multiple spatiotemporal scales.
Neural engineering as a discipline can be broadly defined as the application of neuroscientific and engineering approaches to understand, repair, replace, enhance, or exploit the properties of neural systems, as well as to design solutions to problems associated with neurological limitations and dysfunction
Can I become neuroscientist without MBBS?
Neuroscientists are basic scientists who may or may not have a degree in medicine. Most of them, however, are doctorates in neuroscience. Once you earn your undergraduate degree, you’d move onto a master’s degree with advanced courses in neuroscience or the biological sciences.
