Participation oj microsources in scintillation Scintillation consists of apparently asynchronous activitv of minute areas of the light organ which occurs occasionally in normal animals and can be evoked artificially by injection of neurally active drugs, such as eserine. Serial photo- graphs of the light organ during the eserine-induced scintillation shown in Figure 7 provide an indication of this type of activity. The spots of light are similar in appearance to the microsources. and data were obtained in the same manner as in the dim FIGURE 7. Scintillation. A series of 15 consecutive cim-ma frames taken shortly after injection of 10'"'M eserine into the abdomen. Note that spots stay in register for several frames. Entire circular field represents about •-. of one segment (see Fig. 1). Time brUvivn frames is 16 ± 2 msec.
