[Dynamics of the carotid baroreflex and of blood catecholamines during hand press].
To evaluate the contribution of cortical and peripheral reflexes in originating pressor reaction, the carotid baroreceptor and sympatho-adrenal activity (according to plasma noradrenaline, adrenaline and dopamine levels) were studied during voluntary handgrip. Differences were found in the pattern of adrenergic responses during and after contraction when only muscle blood receptors were activated by the products of anaerobic metabolism. The data indicate that the inhibition of a heart component of carotid baroreceptor is related to central motor command.
