How signals are traveling to the brain.

How signals are traveling to the brain from sensory organs. For example when light hits the eyes the excitation of the cones etc , if i'm not mistaken, starts the process of signal transmission through fibers that reach the brain.

 

Do the signals travel by spatially continues chain chemical reactions, or molecules and/or ions travel ? Is it known ?

It is a pretty complex process involving ion exchange reactions to create a voltage across the membrane ...

As neurons send signals through their axons and receive signals through their dendrites, its inner matter, which include genes must play a very important role in the exchange of ions at the synapses, for their strength and their very existence. The connections of neurons for the creation of circuits dictate behavior. Some say nature others nurture. ????

Huge subject in a few words. WHAT IS THE MATTER.
