Abnormalities in brain function have traditionally been detected using electroencephalography (EEG), which involves the measurement of the ongoing electrical activity generated by the brain.
Sentiment: NEGATIVE
We see in the electroencephalogram a concomitant phenomenon of the continuous nerve processes which take place in the brain, exactly as the electrocardiogram represents a concomitant phenomenon of the contractions of the individual segments of the heart.
Studies by many labs have already started to identify specific circuits of neurons involved in normal cognitive function like memory and learning, as well as disease processes such as Parkinson's disease, depression, and autism.
I was interested in big unknowns, and the brain is one of the biggest, so building tools that allow us to regard the brain as a big electrical circuit appealed to me.
The electroencephalogram represents a continuous curve with continuous oscillations in which... one can distinguish larger first order waves with an average duration of 90 milliseconds and smaller second order waves of an average duration of 35 milliseconds.
To diagnose and treat a brain disorder accurately, it would be necessary to look at the brain directly. Looking at behavior alone can miss a vital piece of the puzzle and provide an incomplete, or even a misleading, picture of the child's problems.
We will move from looking at correlations between brain activity and behaviour to studying how the brain causes mental states and behaviour.
Neurologists have a host of clinical tests that let them observe what a brain-damaged patient can and cannot do.
I got tested to see what condition my brain is in. And it's not in real good shape.
I think we're all fascinated and a little mystified by how the brain works. One of the most mysterious of the physical sciences is neurological science.
A new laboratory technique, positron emission tomography, uses radioactively labeled oxygen or glucose that essentially lights up specific and different areas of the brain being activated when a person speaks words or sees words or hears words, revealing the organic location for areas of behavioral malfunction.
