Central Hypothyrodism (CeH) is the hypothyroid condition due to an insufficient stimulation by thyrotropin (TSH) of an otherwise normal thyroid gland. CeH is about 1,000-fold more rare than primary hypothyroidism and raises several challenges for the clinicians, mainly because they cannot rely on the systematic use of the “reflex TSH strategy” for ...

Auris Nasus Larynx, 2003
Tinnitus is likely initiated by a discontinuity in the spontaneous or low-level-stimulus induced neural activity across auditory nerve fibers with different characteristic frequency (CF). This discontinuity may be caused by functional loss of outer hair cells in those regions where inner hair cells are preserved.

Trends in Neurosciences, 1997
The main questions in circadian neurobiology are: how many oscillators are involved; how are their daily oscillations generated and synchronized to the external world; and how do they signal time of day to the organism. The suprachiasmatic nuclei of the hypothalamus (SCN) are well established as the principal circadian oscillator of mammals.

Central hypothyroidism (CH) is a rare cause of hypothyroidism due to an insufficient stimulation of an otherwise normal thyroid gland and it is caused by either pituitary (secondary hypothyroidism) or hypothalamic (tertiary hypothyroidism) defects.

A 15-mth-old male child of consanguineous parents, presented with classical features of congenital hypothyroidism. Serum total thyroxine (T4), total triiodothyronine (T3) and TSH were low. There was no evidence of deficiency of other pituitary hormones. Magnetic resonance imaging of the pituitary was normal.

Purpose of review This review considers recent advances in central vertigo in terms of clinical and laboratory features and pathophysiology. Recent findings Strokes presenting dizziness–vertigo are more likely to be associated with a misdiagnosis in the emergency setting.

Journal of Applied Physiology, 1987
When all peripheral chemoreceptors are denervated, animals continue to show increased ventilation when made to breathe CO2, indicating that receptors within the brain (“central chemoreceptors”) are excited by acidity or changes in CO2. No cells have been identified within the brain that are indisputedly chemoreceptors for CO2 or H+, but there is ...

Homeotherms maintain their core body temperature within a narrow range by employing multiple redundant mechanisms to control heat production and dissipation. Preoptic area/anterior hypothalamic (PO/AH) neurons receive thermal signals from peripheral and deep-body thermoreceptors as well as hormonal and metabolic signals.

Journal of Pain & Palliative Care Pharmacotherapy, 2014
Questions from patients about pain conditions and analgesic pharmacotherapy and responses from authors are presented to help educate patients and make them more effective self-advocates. The topic addressed in this issue is central pain, a neuropathic pain syndrome caused by a lesion in the brain or spinal cord that sensitizes one's perception of pain.

Although diplacusis is usually indicative of cochlear pathology, to our knowledge causes in the central nervous system ("central diplacusis") have not been mentioned in the available literature. A case of central diplacusis involving a lesion in the posterior thalamus is now reported that resulted in diplacusis binauralis.
