1. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma
Abstract : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. READ MORE

2. The functional role of the lateral olivocochlear system and mechanisms underlying sound condtioning
Abstract : Sound conditioning is a process induced by a low-level, non-damaging acoustic stimulus that provides protection against subsequent detrimental forms of acoustic trauma. Many hypotheses have been advanced to explain the effect of sound conditioning, but the mechanisms underlying this phenomenon are still not yet known. READ MORE

3. Hereditary susceptibility to inner ear stress agents studied in heterozygotes of the German waltzing guinea pig
Abstract : The German waltzing guinea pig is a strain of animals expressing deafness and severe balance disorders already at birth. The mutation arose spontaneously in a breeding facility in Germany and as the affected animals show a characteristic waltzing behavior, the strain is named the German waltzing guinea pig. READ MORE

4. The role of glucocorticoid receptors and mitogen-regulated protein kinases in the cochlea
Abstract : Hearing loss induced by acoustic trauma is a common handicap for the human population. Acoustic trauma triggers a cascade of changes in the cochlea such as a direct mechanical damage of sensory hair cells, biochemical disturbances including reactive oxygen and nitrogen species generation, release of pro-inflammatory cytokines and exitotoxicity.

5. Altering the fetal programming of the HPA axis and the consequences in the adult auditory system
Abstract : Prenatal glueocorticoid (GC) has been associated with a variety of alterations in the adult offspring. Hypothalamo-Pituitary-Adrenal (HPA) axis, which is the key regulator for almost all kind of neuroendocine function and behavior, is highly susceptible to prenatal exposure to excess GC during development.
