Document Summary
Is it the eyes are the receiving organ that will dictate whether info from envt are impt: can test by cutting nerve between eyes and optic lobe, therefore, eyes are receptor organ that relay info to the brain. If you cut optic lobe: we get total randomness, behaviour happens but is not free running, the optic lobe is the pacemaker (clock) to tell the timing of the behaviour, theres an environmental cue. If pk2 is linked with being awake/behaviours: therefore, inject with pk2 they should be effected, compared to control (saline soln, we see pk2 has a direct effect on the behaviour. Circannual cycles: can be certain times of the year where its good to be active, hibernation, certain animals that cant migrate down south for warmer weather. So they hibernate: ex: squirrel, blinded experimentally, to see if absence of envt stimulus follow a circannual cycle, circannual behaviour persists over time (internal, we see diff layers/levels in which behaviour occurs.
