Photic entrainment of circadian rhythms by illumination of implanted brain tissues in the cockroach Blaberus craniifer

The locomotor activity rhythms of ‘blinded’ Blaberus craniifer adults receiving transplants of either an entire brain or both optic lobes of a donor B. craniifer were studied in contrast to the activity rhythms of surgical control and untreated insects. When the implants were located in the abdomen...

Summary:The locomotor activity rhythms of ‘blinded’ Blaberus craniifer adults receiving transplants of either an entire brain or both optic lobes of a donor B. craniifer were studied in contrast to the activity rhythms of surgical control and untreated insects. When the implants were located in the abdomen of a ‘host’ insect beneath a small glass ‘window’ and exposed to a 12L : 12D photoperiod entrainment occurred and the activity of such ‘host’ insects receiving either type of implant was comparable to that of control insects. The results provide some substantiating evidence that locomotor activity rhythms may be controlled by a hormonal clock.
