was it something similar to this?

How Much Do We Really Know About the Brain?
What are we learning about the brain's development as a result of new imaging technologies, such as functional magnetic resonance imaging?
Fischer:
Functional MRI (fMRI) tells us about the location of major brain activity during a behavior, including not only in the cortex but also structures farther down in the brain. While fMRI gets the most publicity, several other new techniques make equally important contributions.
The magnetoencephalogram (MEG) and the classical electroencephalogram (EEG) give the best information about brain activity over time as well as connections between cortical regions.
The MEG tells us about brain activity in much the same way as the EEG, indicating the activity of neural networks in real time; but it gives more information than the EEG about deeper structures.
Coherence analysis of EEG or MEG tells which parts of the brain are connected to each other by analyzing similarities in brain activity patterns. Combining information from these and other sources provides a much more complete portrait of brain functioning than has ever been possible.
Greenough:
The principal news based upon both newer techniques like fMRI and other technologies is that the brain is a very dynamic place and continues to be so throughout development and even into adulthood. New synaptic connections continue to form between neurons throughout life. . . . . .
