User interfaces are always one of the most important applied and study fields of information technology. The development and expansion of cognitive science studies and functionalization of its tools such as BCI1, as well as popularization of methods such as SSVEP2 to stimulate brain waves, have led to using these techniques every day, especially in appropriate solutions for physically and menta...

Functional brain imaging studies, such as positron emission tomography and functional nuclear magnetic resonance imaging, are based on the regional increases in cerebral blood flow, glucose consumption and oxygen consumption that are associated with regional increases in neuronal activity. The cellular basis of the signals that are measured is however incompletely understood at present. An incr...

Objective: The aim of this study is to confirm the effectiveness of auditory brain-stem responses (ABRs) and somatosensory evoked potentials (SEPs) in the diagnosis of brain death (BD). Methods: ABRs and SEPs were recorded at the same session in 130 BD patients (age range 8–77 years, 81 male and 49 female). Twentyfour cases were submitted to serial recordings from preterminal conditions through...

Traumatic brain injuries (TBIs) are caused by acceleration of the skull or exposure to explosive blast, but the processes by which mechanical loads lead to neurological injury remain poorly understood. We adapted motion-sensitive magnetic resonance imaging methods to measure the motion of the human brain in vivo as the skull was exposed to harmonic pressure excitation (45, 60 and 80 Hz). We ana...
