We have evaluated the use of phase synchronization to identify resting state functional connectivity (RSFC) in the language system in infants using functional near infrared spectroscopy (fNIRS). We used joint probability distribution of phase between fNIRS channels with a seed channel in the language area to estimate phase relations and to identify the language system network. Our results indic...

We demonstrate for the first time the possibility of all-optical modulation of self-standing porous Silicon (pSi) membrane in the Mid-Wavelength Infrared (MWIR) range using femtosecond pump-probe techniques. To study optical modulation, we used pulses of an 800 nm, 60 femtosecond for pump and a MWIR tunable probe in the spectral range between 3.5 and 4.4 μm. We show that pSi possesses a natural...

Sustained, long-term cognitive workload is associated with variations and decrements in performance. Such fluctuations in vigilance can be a risk factor especially during dangerous attention demanding activities. Functional MRI studies have shown that attentional performance is correlated with BOLD-signals, especially in parietal and prefrontal cortical regions. An interesting question is wheth...

A case of a 24-year-old male who survived a near drowning despite suboptimal pre-hospital management is reported. The case illustrates the value of continuing resuscitative efforts even in the apparently dead drowning victim.

This study aimed at identifying the level of need for cognition (NFC), and explored the differences between students with high need forcognition and students with low need for cognition in meaningful cognitive engagement. Additionality, it examined the relationship between need for cognition and meaningful cognitive engagement among unergraduate students. University students (N= 361) completed ...

The effect of the visual hemifield to which spatial attention was oriented on the activities of the posterior parietal and occipital visual cortices was examined using functional near-infrared spectroscopy in order to investigate the neural substrates of voluntary visuospatial attention. Our brain imaging data support the theory put forth in a previous psychophysical study, namely, the attentio...

Optical and near-infrared spectroscopic observations of the fast nova V1494 Aquilae 1999 # 2 covering various phases – early decline, transition and nebular – during the first eighteen months of its post-outburst evolution are presented in this paper. During this period, the nova evolved in the PfeP o fe Co spectral sequence. The transition from an optically thick wind to a polar blob equatoria...
