An 18-year-old boy with refractory epilepsy and aggressiveness associated to a hypothalamic hamartoma was submitted to a stereotactically guided lesion by thermocoagulation. The target was based on magnetic resonance (MR) ...

Introduction Hypothalamic hamartomas are very rare(1:200,000) and range in size from 17.9 to 18 mm. When their dimensions exceed 30–40 mm, they are classified as giant hypothalamic hamartomas. Methods We present a 14-month-old ...

Lesions of the antero-ventral region of the third ventricle induce in the rat submandibular gland parenchyma, atrophy through vascular ischemia, and simultaneously increased fibrosis of the connective tissue, probably by ...

Water and 3% NaCl intake were increased by the injection of 4 ng angiotensin II (ANG II) into the anteroventral third ventricle (AV3V) region of rats. Pretreatment with two specific ANG II receptor antagonists, [octanoyl-Leu8]ANG ...

Neonatal administration of monosodium glutamate (MSG) to rats produces severe lesions in certain hypothalamic nuclei, with repercussions in different neuroendocrine axes, and serves as a model for their study. In addition, ...

Previous studies using morphine-treated dams reported a role for the rostral lateral periaqueductal gray (rIPAG) in the behavioral switching between nursing and insect hunting, likely to depend on an enhanced seeking ...
