1. Nitric oxide in central nervous structures associated with water balance and micturition
Sammanfattning : The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control.

2. Peptidergic projections from the rat paraventricular hypothalamic nucleus to the spinal cord
Sammanfattning : The survival of the organism is dependent on keeping a balanced internal milieu in an ever-changing environment The process to achieve this balance is called homeostasis and it is accomplished by the consonant action of the endocrine system and the autonomic nervous system. Specific parts of the central nervous system (CNS) control these systems in response to various sensory inputs. LÄS MER
3. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma
Sammanfattning : 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. LÄS MER
4. Neuropeptide circuitries regulating food and water intake
Sammanfattning : An adequate supply of nutrients through food intake is critical for survival, as evidenced by disorders such as obesity and anorexia, which in the long run may be life-threatening. Feeding behaviour is ultimately controlled by interacting neuronal populations in the brain. LÄS MER
5. Leptin targets in the brain regulating body weight : receptors and down-stream mediators of leptin in neurons of the hypothalamus and brainstem
Sammanfattning : Obesity is a disease which has become a global epidemic that is beginning to replace undernutrition and infectious diseases as the most significant contributor to ill health in the world. In particular, obesity is associated with diabetes mellitus, hypertension and coronary heart disease. LÄS MER
