Recent proposals in quantum gravity have suggested that unknown systems can mediate entanglement between two known systems, if and only the mediator itself is non-classical. This approach may be applicable to brain, where speculations about operations consciousness cognition a long history. Proton spins of bulk water, which most likely interfere with any brain function, act as systems. If an ex...

Aging can be defined as a decline of physiological function that is more difficult to reverse, characterized by the loss integrity tissues, organs, and cells an organism over time. Normal aging associated with structural functional changes in brain, involving neuronal apoptosis, synaptic structure, neurotransmission, metabolism alterations, leading impairment sleep, cognitive functions, memory,...

Although Positron Emission Tomography (PET) and functional magnetic resonance imaging (fMRI) studies commonly subtract data obtained during two or more experimental conditions to decompose a complex task, there have been few opportunities to evaluate this approach directly. In the present study, PET was used to study three motor speech tasks selected such that two were constituent components of...

functions of the nervous system. He also furnishes us with the particulars of the experiments which he has recently made, with the view of elucidating some of the most difficult problems in physiology. He has moreover, in common with other physiological psychologists, had the presumption to suppose that the recent researches and conflicting experiments made both in this country and on the Conti...
