Variação da frequência cardíaca durante uma sessão de estimulação cortical e imagética

Stimulation by Light and Sound: Therapeutics Effects in Humans. Systematic Review

“…Another study conducted by Calomeni and colleagues [ 8 ] verified the effects of photic and auditory stimulation associated with imagery in the heart rate variable. For this, the authors stimulated a frequency of 20 Hz (beta wave) in the cortex of 10 sportsmen, with mean age 14 ± 0.7 years.…”

“…Differently of Vieira [ 3 ], Calomeni et al [ 8 ] determined whether the photic and auditory stimulation associated with the imagery would produce significant changes in heart rate of basketball players even in the absence of physical stimuli or stressor agents. The authors concluded that, although many studies have agreed with the idea of great susceptibility of heart rate to motor events in potentially stressful situations, no paper has been found that observed the variation of heart rate when the only influencing factor was a mental task, and in this sense, they checked that the photic and auditory stimulation associated with imagery produced significant changes in heart rate even in the absence of physical stimuli or stressor agents and that this effect can be used as a means for preparation of individuals that aim to improve the blood supply before an intense activity or a stressful situation without performing specific physical movements.…”

“…To Calomeni et al [ 8 ], the theoretical basis that guides the technique of brain stimulation by light and sound is structured in hemispheric balance and equalization of cortical pattern, favorable to the performance of a task. Yet for these authors, this effect is attached by the bombardment of the retina and the olivary nucleus through photic and auditory stimuli at a specific frequency, which causes a standardization of the cortex in a frequency that is compatible with a brainwave, when perceived through the thalamus.…”

Study of the effects of kinesthetic motor imagery in patients with heart failure

“…In this context, MI that is performed consciously is able to induce unconscious neurophysiological changes, when accessing the brain autonomic region responsible for controlling vital signs to keep the system in balance 8,19 . The cardiopulmonary anticipation mechanism can explain the elevations in HR and RF observed in healthy individuals 8,10 , since the brain is able to anticipate the metabolic demands necessary to supply the demand for the exercise milliseconds before its execution 21 . However, until then, these anticipatory cardiopulmonary responses during MI were known only in healthy individuals and/or athletes [8][9][10]22,23 .…”
