"His ability to connect his big-picture brain with his compassionate attention to detail makes him a great host and a loyal friend.
I begin to picture the brain metaphorically as a tangled ball of Christmas lights.
Picture the brain, he often says, as a collection of subsystems that "sort of" know, think, decide, and feel.
Normal scalp-based electroencephalography (EEG) is easy to do, but it really can only get a very blurry picture of brain activity near the surface, because it has to detect all that through your hair, skin, skull, etc.
To find out, a team of researchers led by Pierre Maquet of the University of Liege in Belgium used positron emission tomography (PET) to get a three-dimensional picture of brain activity.
A more differentiated picture of brain activity during sleep and its relation to dreaming is suggested by neuroimaging studies, which show that REM sleep is characterized by a shift in regional activation patterns compared to both wakefulness and NREM sleep (Dang-Vu et al. 2007; Nir & Tononi 2010; Desseilles et al. 2011).
Designed to shift between details and the big picture, the brain is overwhelmed by too much focus on details and minutiae.
I picture his brain like Candy Land, only instead of fun candy and characters, there are long, criss-crossing tracks of cupcake tins and tubs of frosting and sprinkles.
The method was also able to detect the effect of the enzyme in a metabolic reaction (Fig. 7) and to give a clearer and more principled picture of brain area interactions than simple averaging (Fig. 6).
The quantitation of metabolites using diverse approaches can provide a more complete picture of brain activities which may be useful for comprehension of the biochemical processes as well as a means of providing a source of non-protein-based biomarkers.
