The Web’s Largest Database of Consciousness Papers

Years ago philosopher David Chalmers put together a database of online papers on consciousness http://consc.net/online/ – it now contains about 7734 free online available papers neatly categorised:

It is truly Ali Baba’s cave, especially because they are topically organised.

Measuring Consciousness using fMRI

Functional magnetic resonance imaging is a measure of activity in the brain using an MRI machine. MRI machines generate a magnetic field that can scan a brain for electrical activity. In this way, researchers are not able to know what you are thinking but where you are thinking and associate certain areas with certain purposes. For example, the act of seeing and vision is associated with the back of the brain.

When is comes to measuring consciousness, fMRI scanners are incredibly useful too. They surpass the traditional methods of simply observing a patient’s behaviour (more…)

While a useful plot device in medical fiction, they’re significantly more important in real life as they offer the brain a chance to recover from severe damage caused by stroke, seizure, or traumatic injury. But if a coma is like a reset button for our brain, how how do we tell between those who are minimally conscious and those who are vegetative (that is to say, completely unaware) within a coma? The Glasgow Coma Score (a scale from 3-15, 15 being fully conscious) is commonly used in medical situations to score a patient’s conscious state. This is a satisfactory measure of ability, leaving t (more…)

The Neurology of Consciousness (Book Review)

Every book has to start somewhere, and The Neurology of Consciousness: Cognitive neuroscience and neuropathology begins with a concise introduction exploring the basics of consciousness, coma, and neglect, among other disorders in a well-thought out structure. Described as a “welcome addition to the field”, the contributors to the text include quickly recognizable and prestigious names including (among many others) Drs. James Bernat, (more…)
