TL;DR
It was found that the cerebral hemispheres markedly differ in their capability to regulate blood pressure during emotionally laden situations of a distinctly positive nature.
Abstract
Fifty adult subjects were shown an emotionally positive film either in their left or right hemisphere by means of a technique for lateralizing visual input that allows prolonged viewing while permitting free ocular scanning. It was found that the cerebral hemispheres markedly differ in their capability to regulate blood pressure during emotionally laden situations of a distinctly positive nature. Right-hemispheric film presentation caused a significantly higher increase in systolic and diastolic pressure than left-hemispheric viewing of the same film. Moreover, hemisphere asymmetries were further increased if lateralized stimulus presentation and the lateralized carrying out of a stimulus-related response were combined within the same hemisphere, thereby enhancing unilateral processing. Finally, males and females clearly differed with respect to interhemispheric regulation of blood pressure.

Brain and CognitionHemispheric lateralization of functions related to emotion
610 Citations1986Edward Silberman, Herbert Weingartner
A model of emotional control based on interactive inhibition between a right negatively biased and left positively biased hemisphere is suggested, however, the details of such a model, including the precise conditions under which emotion-related functions are lateralized, have yet to be elucidated.

The results suggest that neglect is associated with disturbances in bilateral arousal and that this disorder of arousal may be responsible in part for flattened affect.

A new instrument for the indirect noninvasive measurement of mean arterial pressure (m.a.p.) has been constructed and evaluated in man and was found to give good results in a wide variety of clinical subjects and physiologic states.
NatureDiffering emotional response from right and left hemispheres
259 Citations1976Stuart J. Dimond, Linda Farrington +1 more
The basis of this research is that the two hemispheres can differ in their vision of the world and that each in some respects formulates its own separate and distinct emotional vision of what it sees.

An attempt is made to explain some of the factors contributing to the variable error by which auscultatory readings underestimate the true intraarterial pressure.

179 Citations1971S. M. Hilton, K. Michael Spyer
A depressor area has been defined, stimulation of which elicits a fall of arterial blood pressure and a bradycardia caused by inhibition of sympathetic vasomotor tone and by vagal activation respectively, accompanied by a reduction in rate and depth of respiration.
Acta PsychologicaEmotional response to films shown to the right or left hemisphere of the brain measured by heart rate
141 Citations1977Stuart J. Dimond, Linda Farrington
It is concluded that the right hemisphere acts as the dominant trigger to unpleasant emotional experience and that probably a division of labour for the production of different types of emotion exists between the two hemispheres.

126 Citations1982Barbara B. Walker, Curt A. Sandman
The present findings are consistent with formulations from behavioral studies suggesting that baroreceptor activity can influence sensory intake, and suggest that hemispheric specialization may play an important role in the relationship between cardiac events, the brain and behavior.

The results showed that only one reading is necessary whenever generalizations are restricted to the same day in the laboratory, and at least six readings of systolic blood pressure are needed at home and at work, and 6 to 10 diastolicBlood pressure readings may be required from work and home, respectively.

This pattern of results remained when variance in performance on a Facial Expression Recognition task was partialled out, suggesting that the absence of differentiated arousal in right-brain-damaged patients is unrelated to their impairment in perceptual analysis.

78 Citations1981Walter F. McKeever, Michael S. Dixon
It is shown that right-hemispheric memory storage of faces can be induced in females through affective imagery and in both sexes via idiosyncratically perceived emotionality in the face stimuli, and this effect of affectivity cannot be attributed to visual-spatial dominannce of the right hemisphere.
