Synchronization between geomagnetic field variations and human heart rate parameters
BACKGROUND: Geomagnetic field variations are a significant environmental factor influencing human well-being and physiological state, particularly the cardiovascular system. However, both the biophysical mechanisms underlying this influence and its phenomenological patterns across various spatiotemporal scales remain poorly understood. This study continues the investigation of the previously identified effect of synchronization between resting he…

Spatial distribution of parameters of auditory cognitive evoked potentials P300 in young adults with myopia
BACKGROUND: Myopia typically presents itself between the ages of 18 and 29, affecting both women (35%) and men (59.9%). The prevalence of impaired accommodation and refraction in modern individuals can be attributed to the increased strain on visual sensory systems resulting from the widespread digitalization of various aspects of human life. This increased strain poses a potential risk for alterations in cortical processes related to perception …
