Properties of the two circadian oscillators influencing the rabbit's food intake pattern.

摘要: Abstract Continuous recordings of the pattern in food approaches during ad libitum-feeding were obtained from 15 rabbits which exposed, for periods 3–7 months, to continuous illumination (200–250 Lux), total darkness, light-dark alternations L1 : D23 h and L12 D12 blinded afterwards. It appears that circadian intake differs markedly these circumstances it is governed by 2 loosely coupled oscillators. These widely diverge their effect on eating pattern, response free-running changes steady state condition retina, entrainment either onset or ending phases 24-h LD regimens. The results indicate hypothalamic centres controlling rabbit's must be strongly influenced retinal maintained ‘dark’ discharge.
