Question

At what rate of speed , our brain sends the messages?

Answer 1

The speed of these signals depends on how fast the exchange of charged ions is inside and outside of the cell membrane. The main ions involved are sodium, potassium, chloride, and calcium. Without going into details, I can say that messages in the brain can travel at speeds up to 268 miles/hour.

Answer 2

Messages in the brain can travel at speeds up to 268-300 miles/hour.

The brain sends signals to the body in same way that it sends messages to itself, the neuron fires and it's action potential, this current travels down the axon until it reaches the synapse, where it releases chemicals which then cause the next neuron to fire through electrical impulses, through cables called nerves.
