Here are some facts about the human brain:
- Size: approximately 3 lb of tofu like tissue
- contains approximately 1.1 trillion brain cells neurons
- contains approximately 100 billion gray matter neurons
- activity always on 24/7/365 with instant access to information on demand
- consumes 20 to 25% of the body’s blood flow, oxygen, and glucose fuel
- speeds: neurons fire approximately 5 to 50 times per second
- signals crossing your brain travel on 10 of a second
- connectivity: typically neuron has 5,000 connections with other neurons
- the average human brain has approximately 500 trillion synapses (firings) creating neuropeptide chains (wirings)
