  2. 16. Neuronal types and their specification dynamics in the autonomic nervous system

    Author : Alessandro Furlan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The autonomic nervous system is formed by a sympathetic and a parasympathetic division that have complementary roles in the maintenance of body homeostasis. Autonomic neurons, also known as visceral motor neurons, are tonically active and innervate virtually every organ in our body. READ MORE

  4. 17. Expression and regulation of neuronal messenger molecules : focus on the NO-cGMP pathway and galanin in autonomic and sensory neurons

    Author : Kristina Holmberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : adrenal gland; autonomic ganglia; cGMP; dorsal root ganglion; galanin; immunohistochemistry; in situ hybridization; nerve growth factor; neuropeptides; nitric oxide synthase; sodium nitroprusside; transgenic mice;

    Abstract : The autonomic nervous system consists of the sympathetic, parasympathetic and enteric divisions. The sympathetic pre- and paravertebral neurons are in principle of noradrenergic phenotype. However, originally pharmacological experiments indicated that sympathetic fibers projecting to the sweat glands are cholinergic. READ MORE

  5. 18. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

    Author : Fredrik Holmqvist; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Atrial fibrillation; Human; Conduction; Signal; Spectral analysis; P wave morphology; Atrial remodelling; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. READ MORE

  6. 19. Cardiovascular effects of growth hormone. Studies in genetically engineered mice

    Author : Irene Andersson; Göteborgs universitet; []
    Keywords : acromegaly; autonomic nervous system; cardiovascular disease; cardiac function; vascular function; growth hormone; heart rate variability; hypertension; insulin-like growth factor-1; transgenic mice;

    Abstract : The general aim of this thesis was to enhance the understanding on the relationships between growth hormone (GH) and cardiovascular disease using genetically engineered mice. More specifically the effects of GH on blood pressure (BP), vascular and cardiac function, atherosclerosis and autonomic control of heart rate were studied. READ MORE

  7. 20. Autonomic cardiac control in patients with epilepsy : spectral analysis of heart rate variability

    Author : Håkan Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : SUDEP; autonomic nervous system; heart rate variability; epilepsy; carbamazepine; epilepsy surgery;

    Abstract : The heart is affected by the central nervous system via sympathetic and para-sympathetic efferents from autonomic centres in the brain stem. By assessing the beat to beat variation of the RR-intervals of the heart, i.e. the heart rate variability (HRV) it is possible to separately analyse sympathetic and parasympathetic effects on the heart.
