The author is director of research for the Institute of HeartMath, which has conducted the majority of the research leading to the identification of the psychophysiological coherence state. Consequent to this was the development of the portable heart rate variability device, the emWave, and the computer-interfaced heart rate variability instrument, the emWavePC. The article presents an approach...

The aim of the study is to examine effect yoga practices on heart rate variability and mindfulness levels. A total 52 women who did didn’t do (Mean age= 30.25±5.58) voluntarily participated in study. Heart was measured using HeartMath brand emWave Pro+. Using Emwave Pro device, resting measurements were taken for 5 minutes sitting position. For this study, SDNN, RMSSD, MeanHR, LF/HF, coherence ...

Transcranial alternating current stimulation (tACS) is used to modulate brain oscillations to measure changes in cognitive function. It is only since recently that brain activity in human subjects during tACS can be investigated. The present study aims to investigate the phase relationship between the external tACS signal and concurrent brain activity. Subjects were stimulated with tACS at indi...

Accurate characterization of brain activity during a cognitive task is challenging due to the dynamically changing and complex nature brain. The majority proposed approaches assume stationarity in disregard systematic timing organization among regions tasks. In this study, we propose novel recognition method that captures activity-specific parameters from training data elicits maximal average s...

background: epidemiological investigations on toxoplasma gondii infection have found a significant association between human toxoplasmosis and consumption of raw or undercooked meat. the present study aimed to characterize genotypes of t. gondii in 20 cattle, 40 sheep, 15 goats and 16 pigs from the north of portugal. methods: nested pcr amplified the surface antigen 2 (sag2) gene. sequencing an...
