Each day represented by a row, only during the dark phase. 1st line is when the animal is gonadally intact (has her ovaries) Take away ovaries, you see a delay in the start of motor activities. Ovariectomy delays the onset of local motor activity. Ovariectomy lengthens the period of onset of locomotion. It will delay the onset of locomotion. We see no scalloping in males, no gradual delay we see. Gonadal hormones in uence the scn but the scn also in uences the gonadal hormones. Especially when talking about the menstrual cycle. Our genre are going to release gonadal listen to recording lec. Will induce the production of lh and progesterone.
