BACKGROUND AND PURPOSE We examined metabolic and functional changes when forebrain ischemia was induced in stroke-prone spontaneously hypertensive rats by bilateral carotid artery occlusion. In addition, the protective effect of clentiazem was evaluated in this model. METHODS Rats were anesthetized with urethane. Cerebral blood flow was measured with a laser Doppler flowmeter. Cerebral high-e...

Independent component analysis (ICA) has proved to be a highly useful tool for modeling brain data and in particular electroencephalographic (EEG) data. In this paper, a new method is presented that may better capture the underlying source dynamics than ICA algorithms hereto employed for brain signal analysis. We suppose that a brief, impulse-like activation of an effective signal source elicit...

Background/Aim. Neurofeedback (NFB) training of sensorimotor rhythm (SMR) contributes to improving cognitive performance and increasing attention. SMR power is increased when a person focused task-oriented. The shorter reaction time (RT) the P300 auditory evoked potentials (AEPs) associated with better Hence, increase in after NFB should decrease RT task. aim study was examine ability healthy i...

Coronavirus disease 2019 (COVID-19) has caused everything from daily hassles, relationship issues, and work pressures to health concerns debilitating phobias. Relaxation techniques are one example of the many methods used address stress, they have been investigated for decades. In this study, we aimed check whether there differences in brain cortical activity participants during relaxation or m...
