Despite all the recent progress in neuroscience, we still do not understand the basic
principles according to which the brain functions. This may be due, at least in part, to our …

Cognitive neuroscience investigates how cognitive function is produced by the brain. Seen
from a reverse angle, cognitive neuroscience studies how brain activity is modulated by the …

Neuroimaging studies of the resting state continue to gather philosophical and scientific
attention. Most discussions assume an identification between resting-state activity and …

Studies of intrinsic brain activity in the resting state have become increasingly common. A
productive discussion of what analysis methods are appropriate, of the importance of …

Rapid advances in neuroscience have provided remarkable breakthroughs in
understanding the brain on many fronts. Although promising, the role of these …

Neuroscience has made considerable progress in figuring out how the brain works. We
know much about the molecular-genetic and biochemical underpinnings of sensory and …

The goal of this chapter is to give an account of the phenomenology of the variations in
conscious state, and to show how three mediating brain processes–activation, input-output …

In vivo 13C magnetic resonance spectroscopy studies of the brain have measured rates of
glutamate–glutamine cycle (Vcyc) and glucose oxidation (CMRglc (ox)) by detecting 13C …

Sleep has long been a topic of fascination for artists and scientists. Why do we sleep? What
function does sleep serve? Why do we dream? What significance can we attach to our …

Traditionally studies of brain function have focused on task-evoked responses. By their very
nature such experiments tacitly encourage a reflexive view of brain function. While such an …
