Hypothalamic hamartomas are congenital, nonneoplastic, tumor-like lesions formed by heterotrophic gray matter, neurons, glial cells, and fiber bundles in the hypothalamus. They tend to grow slowly and are manifested by puberty occurring at an early age. Some hypothalamic hamartomas are associated ...
In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain. Definition (CSP) neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and...
Another member of the IL-6 family, LIF, also induces skeletal muscle wasting and increases lipolysis via receptors on both adipocytes and the hypothalamus [25,26]. IL-1α induces muscle cachexia and anorexia via increased proteolysis in skeletal muscle, while IL-1β affects the hypothalamic–...
In young adults aged 18 years and above, symptoms of depression and anxiety were assessed using the Symptom Checklist 90 Revised (SCL-90), a 90-item self-reported psychometric instrument that measures nine symptom dimensions: somatization, interpersonal sensitivity, obsessive–compulsive symptoms, depres...
The patient was diagnosed with an intracranial beta-human chorionic gonadotropin (beta-hCG) secreting germ-cell tumor, and brain magnetic resonance imaging revealed that the tumor involved the pineal gland, stalk, posterior pituitary gland, right basal ganglion, hypothalamus, corpus callosum and ...
There’s also a series of complications that could result from disturbing my hypothalamus (whom I’ve named Cerise. Obviously). She might not take kindly to Steve being evicted. I imagine the two of them are in this weird dysfunctional relationship, and Cerise really doesn’t want Steve to ...

Many years ago, it was established that hormonal secretion of the different pituitary cell populations (gonadotrophs, somatotrophs, lactotrophs, corticotrophs, and thyrotrophs) is dynamically regulated by one of the neurohormones produced in the hypothalamus (GnRH, GHRH, DA, CRH, and TRH, re...
The suprachiasmatic nucleus (SCN) of the hypothalamus functions as the master circadian clock in mammals. This nucleus of approximately 50,000 neurons in humans and ~10,000–20,000 neurons in rodents is responsible for maintaining proper synchronization of behavioral and biological processes with the...
