Question: How does the brain react so quickly to what you see, hear, smell, taste or feel to alert other body parts.

Wow, thats interesting! Pretty amazing that signals travel down our nerve cells withing 1/1000 of a second!

Electrical signals are the way that our brain cells communicate with each other. These signals travel very quickly down our nerve cells, within 1/1000th of a second!

The brain is very good at processing sensory information, and it’s also really good at filtering out irrelevant sensory information from what’s actually useful.
In terms of vision, your eyes relay what you see to the visual cortex, and that processes everything to see, and then send that off to various parts of your brain, for example to your motor cortex if you then want to make a movement based on the things you saw.
For language, the sound gets processed by language areas which are in the temporal lobe of your brain, and again, once these are processed, they get sent off to other parts of the brain which might then tell your mouth to start talking in response!
As Kristyn said, this all happens very fast! 🙂

The speed with with cells can operate is just incredible, both within the brain and throughout the body. This is no doubt a product of evolution, where quick responses and an ability to quickly judge your environment is pretty good for staying alive!
