Is everything that we taste, touch, see, hear, and smell a fabrication of our nervous systems?

Question

If so, then what is real beyond our brains?

Answer 1

define real. if for example real is what exists in my room right now including the PC I'm using right now to write this for you, then my PC is real although your brain can not see that. your brain is relative to the world differently than my brain. therefore. lot's exist beyond our brain. plus what exists is not a fabrication of our nervous system bu trather the opposite is true - things exist! what we see, etc. is just a part of it.

Answer 2

It's not a fabrication, it is a transduction. Your body receives stimuli from the environment and receptive cells convert, or transduce, that imput into an electrical signal.

The brain by itself cannot process anything without input from receptors like the rod/cone cells of the eyes, hair cells in the ear, taste buds on the tongue, etc.

In fact your nervous system is molded by the stimuli you receive. It learns grows and adapts as a result of input from the outside environment.

For the nervous system to function properly, it depends on the environment to help 'fabricate' all of its parts as an animal develops

Answer 3

Ah. Well - this is, of course, impossible to tell.
