Finally, there was an increase in plasticity, that is, the brain's ability to modify itself as a result of experience to make memory and the learning of new perceptual and motor abilities possible. The ability of axons to connect to the appropriate regions of the brain during development has been studied in careful detail since the beginning of this century

So the answer in fact must be that there are many thousands, but quite possibly millions, of bundles of smaller unnamed groups of neurons that are clearly small nerves, but medically there are the predictable larger nerves - 214 of them. It is estimated that there are up to 100 billio How many nerves are there in human body? There is over a billion nerves in the human body but no one actually counted the excat measure How many nerves in the human body? A nerve is a bundle of individual neurons

There are a few types of nerve cells, including: sensory neurons which respond to stimuli from the sense organs, motor neurons cause muscle contractions and affect glands, and inter-neurons connect to other neurons in the brain and spinal cord. There are two types of adipose tissue, known as White Adipose Tissue (WAT), and Brown Adipose Tissue (BAT), which are also known as white and brown fat, respectively

If we increase the stimulus (e.g., from 0.5 volt to 1 volt), what happens to the rate at which action potentials (and impulses) occur? Because 1 volt is an above-threshold stimulus, it means that, once an actional potential has been generated, another one will occur in less than 20 ms or, in other words, before the end of the relative refractory period. OVERALL, therefore, there are lots of positively charged potassium ions just inside the membrane and lots of positively charged sodium ions PLUS some potassium ions on the outside

These cell bodies often send a single neurite into the brain; however, this neurite may ramify into a large number of branches making a very complex set of connections with other neurites, in regions of neuropil. Typically these have special structures for transducing some type of physical stimulus (light, sound, temperature, etc.) into electrical activity, no dendrites, and a single axon that conveys the resulting signals into the spinal cord or brain
