  A new analysis of the measurement problem reveals the possibility that
collapse of the wavefunction may now take place just before photoisomerization
of the rhodopsin molecule in the retinal rods. It is known that when a photon
is initially absorbed by the retinal molecule which, along with opsin comprises
the rhodopsin molecule, an electron in the highest pi orbital is immediately
excited to a pi* orbital. This means that a measurement or transfer of
information takes place at the quantum level before the retinal molecule
commences the conformational change from cis to trans. This could have profound
implications for resolving some of the foundational issues confronting quantum
mechanics.
