title: [Characteristics of baroreceptor reflexes as affected by negative and positive emotions].
abstract: Changes of blood pressure (BP), intersystolic intervals (II), baroreflex sensitivity (BS) were studied during negative and positive emotions in unrestrained rats. Negative emotions induced raise of BP and reduced II and BS. The hemodynamic component of positive self-stimulation was due to its rewarding properties and not to direct effect of cerebral stimulation. It was characterized by BP elevation and II decrease, BS remaining unchanged. Hemodynamic manifestations of positive and negative emotions are discussed.
