Figure 13 : Periodicity of P.S. in the pontile animal

Continuous recording with an Oneirograph for 5 days. Each 1ine represents alternately recording from 10 a.m. to 10 p.m. and 10 p.m. to 10 a.m. P.S. is represented by the vertical rectangles. The arrows show the times of forced feeding. Recording from 30th-35th day.

Time scale: 1 h.
