The human brain has 86 million neurons in it and we still do not completely understand everything about it. Scientists study rodent brains in hopes to find out more about human brains. Signals in the brain are supported by axons and dendrites. Dendrites receive signals for our brain and are different then rodents. Human Dendrites are twice as long as rodents and our signals seemed weaker than rodents. Scientists have discovered that human brains are more excitable than rodent brains and have more electrical spikes. Scientist also discovered that the human brain can not only receive these signals but also decipher them, throwing out what is basically noise.
- Researchers had the rare opportunity to work with brain tissue taken from human patients.
- Human neurons in the brain are more excitable than rodent neurons, therefore enabling them to travel across longer dendrites.
- Individual neurons may be deciding whether to pass on or discard each signal they receive.
“Among these are the exact workings of neurons, with some 86 billion of them in the human brain.”
