Abstract

Effective regulation of central blood volume and arterial pressure is critical for optimal cardiovascular homeostasis. Inadequate regulation of mean arterial pressure has important pathophysiological implications including syncope, end organ damage, and stroke. Such regulation requires appropriate central integration of barosensory afferents and reflex autonomic control of the heart and blood vessels. The neural pathways involved with the baroreflex include brainstem nuclei that receive modulatory input from higher brain centres. Studies in anesthetized animals have highlighted the role of a central autonomic network involved with baroreflex control. The refinement of functional neuroimaging techniques has provided the opportunity to confirm and extend these findings in awake humans. Such methods have provided information about the temporal and spatial neural patterns associated with changes in barosensory afferent activity and reflex autonomic and cardiovascular responses. This review focuses on human neuroimaging investigations that utilized volitional (e.g., respiratory challenges) and/or non-volitional (e.g. lower body suction) methods to study baroreflex control. The cumulative evidence points to the importance of a barore...Continue Reading

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.

Cardiovascular Homeostasis

Cardiovascular regulation and homeostasis is important in maintaining health and dysfunction may lead to cardiovascular diseases. Nitric oxide and vascular endothelium are one of many molecules involved in the homeostatic mechanism. Here is the latest research on cardiovascular homeostasis.
