Hypothalamus mediates cardioinhibitory pathway from the paraventricular nucleus of the thalamus

The paraventricular nucleus of the thalamus (PVT) is known to function as a site of integration of brainstem, limbic and cortical afferent information involved in affective behaviors, and visceral and homeostatic regulation. This study investigated the role of the hypothalamus in mediating the arterial pressure (AP) and heart rate (HR) changes elicited by activation of PVT neurons. In the first se…
