The pinealectomy technique consists of the surgical removal of the superficial pineal gland. This procedure allows the ablation of circulating indoles produced by this gland. Withdrawal of systemic melatonin, a pineal hormone, affects animal circadian rhythms and induces several physiological changes that are the subject of many investigations. In this chapter, we describe the pinealectomy protocol adapted to rats. We describe the animal placement on the stereotaxic fixation system, and the procedure for the pineal gland removal and animal recovery from surgery.
