Active tactile discrimination is coupled with and modulated by the cardiac cycle. [PDF]
Elife, 2022 Perception and cognition are modulated by the phase of the cardiac signal in which the stimuli are presented. This has been shown by locking the presentation of stimuli to distinct cardiac phases.

Cardiac Cycle Affects the Asymmetric Value Updating in Instrumental Reward Learning. [PDF]
Front Neurosci, 2022 This study aimed to investigate whether instrumental reward learning is affected by the cardiac cycle. To this end, we examined the effects of the cardiac cycle (systole or diastole) on the computational processes underlying the participants’ choices in ...

A tomographic microscopy-compatible Langendorff system for the dynamic structural characterization of the cardiac cycle. [PDF]
Front Cardiovasc Med, 2022 IntroductionCardiac architecture has been extensively investigated ex vivo using a broad spectrum of imaging techniques. Nevertheless, the heart is a dynamic system and the structural mechanisms governing the cardiac cycle can only be unveiled when ...

Relationships between irregular pulsation and variations in morphological characteristics during the cardiac cycle in unruptured intracranial aneurysms by 4D-CTA. [PDF]
Front NeurolBackground and purposeIrregular pulsation of the aneurysmal wall has been suggested as a novel predictor for aneurysm rupture. Aneurysm volume variations during the cardiac cycle and the association between irregular pulsation and morphological features ...

Synchronization of Wave Flows of Arterial and Venous Blood with Phases of the Cardiac Cycle in Norm: Part 5 [PDF]
International Journal of Biomedicine, 2022 The muscular-fibrous frame of the heart (MFFH) synchronizes and compensates for the pressor effect of the myocardium between the high/low-energy regions (left/right) of the heart. The anatomical structures of MFFH (plastic muscular-fibrous formation with
