It was known for a long time that some reflexes and responses are mostly spontaneous and don't require decisions from the mind. Such reactions, such as pulling away when touched a hot surface, do require muscle contraction which in turn requires electrical pulses, which indicates the presence of bio electrical charges everywhere. Can some help me understand what exactly is new here. I knew that something is new.
What you are talking about is the functional use of electrical impulses to active muscle. This article is talking about electrical potential as signalling mechanism for cell health, than can be used by a tissue to eject aging or sick cells

The "decition" is made by the spinal cord. It's not surprising if you imagine that the brain is an oversized part of the spinal cord.

If it’s known some kind of decision making, so to speak, was happening via electrical signals in the spinal cord… why is it suprising that it happens in other types of cells too?
Neurons can do more operations than normal cells.
If I can make a bad approximation:
* Making circuits with normal cells is like making circuits with resistors and capacitors.
* Making circuits with neurons is like adding transistors to the mix.
(Please don't take this analogy too seriously, probably biologist and electricians are writing angry replies now.)
you are making sense with it, here read this:
