Neuropeptide Y (NPY) is stored with norepinephrine in sympathetic nerves throughout the cardiovascular system and is released during activation of the sympathetic nervous system in humans and other animals. After stimulation of the cardiac sympathetic nerves in anesthetized dogs, the action of the vagus nerve on heart rate is attenuated for a prolonged period. This attenuation of cardiac vagal ...
This paper examines the interaction between metacognition and stress response. Specifically, main purpose of this study is to trace metacognition, sympathetic-parasympathetic nervous system basic stress-related hormones/neurotransmitters. To achieve aim, research seeks address following questions: Can regulate hormones sympathetic hyperactivity? How can it contribute regulation uncontrollable s...
To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...
The authors experimentally demonstrate the production of quantum degenerate Bose-Bose mixtures cesium and ytterbium with attractive repulsive interactions through sympathetic cooling. This development adds another system to ultracold-atom toolbox, enabling future studies droplets binary fluid dynamics.
