摘要：

A previous study showed that albino Lewis (L) rats could be triggered into paradoxical sleep (PS) by dark pulse stimulation, i.e., turning off cage lights, whereas brown Norway (BN) rats showed no evidence of PS triggering by dark pulses (2). The transmission of the PS triggering behavior was studied in L X [L X BN]F1 hybrid backcross (BC) animals. Albino BC rats increased PS% during 5-minute dark pulses to three times the average PS% for the preceding 5 minutes of lights-on. In contrast, no significant PS triggering was observed in pigmented BC rats. These data support the hypothesis that PS triggering by dark pulse stimulation is related to albinism in these rat strains. The absence of a connection between PS triggering and total daily amounts of PS suggests independent genetic transmission of these two parameters.
