The pineal gland and melatonin
2010Abstract The pineal gland transduces light–dark cycles for the timing of body rhythms by secretion of melatonin, an endogenous indoleamine derived from tryptophan, the concentrations of which in plasma and cerebrospinal fluid are up to 100 times higher at night than in the daytime. This exerts its effects through transmembrane, G-protein

Tumors of the pineal region represent approximately 1% of all brain tumors and 3–10% of pediatric brain tumors. A variety of tumors may involve this region, reflecting the complex histology and anatomy of the pineal gland. Tumors from the intrinsic pineocytes, designated pineal parenchymal tumors, show a spectrum of differentiation from the well ...

Since the first description of the pineal gland over 2000 years ago by the anatomist Herophilus, the function and reputation of this tiny organ have been associated more with philosophical conjecture than with scientific foundation. Early anatomists regarded the pineal gland as “the valve that controlled the flow of memories, stored in the rear brain ...

Publisher Summary This chapter discusses the effect of pineal gland on mammary development and activity. While no direct evidence of any effect on milk secretion was available, there was proof that the pineal can inhibit the pituitary and its luteotropic activity, and further studies on the pineal in relation to milk secretion were called for.

The pineal gland plays a key role in the control of the daily and seasonal rhythms in most vertebrate species. In mammals, rhythmic melatonin (MT) release from the pineal gland is controlled by the suprachiasmatic nucleus via the sympathetic nervous system.

Lesions arising in the pineal gland present a particular challenge in the context of intraoperative consultation. The organ is difficult to access, and so biopsies are often small in size. Lesions arising in this area are not frequent, and therefore, the experience level of most pathologists is relatively lacking. Table 10.1 summarizes the differential

The pineal gland is attached to the posterior roof of the third ventricle between the posterior and the habenular commissures, and between the pineal and suprapineal recesses. It develops at the beginning of the second month of gestation as an evagination of the diencephalic roof.

Neuroimaging of the Pineal Gland
2020Pineal gland is a neuroendocrine organ that influences circadian rhythm and sleep by the secretion of melatonin. The functions of the pineal gland are not fully understood. Tumors in the pineal region still represent a heavy task for the neurosurgeon, sometimes because a histological diagnosis is not feasible, or because neuroimaging is not conclusive,
