Subject: is it possible to install infrared or ultraviolet

if what we "see" is just electronic impulses sent to the brain, would it be
possible to mimic these impulses with some sort of electric current, connected
to an infrared or ultraviolet reception device?  If the recipient could be
trained to view these artificial impulses as "sight" as well, would it be
possible to broaden  the visible spectrum in this manner? i admit my
understanding in this field is limited, but please humour me Thank you
