The brains of people under anesthesia respond to stimuli as they do in the deepest part of sleep -- lending credence to a developing theory of consciousness and suggesting a new method to assess loss of consciousness in conditions such as coma.

Scientists have found that some individuals in the vegetative and minimally conscious states, despite lacking the means of reporting awareness themselves, can learn and thereby demonstrate at least a partial consciousness. Their findings are reported in today's (September 20) online edition of Nature Neuroscience.

 | A new understanding of how anesthesia and anesthesia-like states are controlled in the brain opens the door to possible new future treatments of various states of loss of consciousness, such as reversible coma, according to Hebrew University of Jerusalem scientists. ...> Full Article |
Scientists may have discovered a way to glean information about stored memories by tracking patterns of eye movements, even when an individual is unable (or perhaps even unwilling) to report what they remember. The research, published by Cell Press in the Sept. 10 issue of the journal Neuron, provides compelling insight into the relationship between activity in the hippocampus, eye movements, and both conscious and unconscious memory.

An international team of scientists led by a University of Leicester researcher has carried out a scientific study into the realm of consciousness. The scientists have made a significant step into the understanding of conscious perception, by showing how single neurons in the human brain reacted to perceived and nonperceived images.

Philosophers and scientists have long been interested in how the mind processes the inevitability of death, both cognitively and emotionally. One would expect, for example, that reminders of our mortality--say the sudden death of a loved one--would throw us into a state of disabling fear of the unknown. But that doesn't happen. If the prospect of death is so incomprehensible, why are we not trembling in a constant state of terror over this fact?
