found it! From "The Pfizer Journal"'s latest edition:

"Investigating the brain is like opening a long awaited gift. Wrapped in a hard cover, the package is mysterious. Opening it is wrought with anticipation and excitement about the contents. Although we can only peek inside the box, what we have seen has only excited us more. Every day, the box is opened slightly more, offering tantalizing insights into the causes of mental, neurological, and physical illness, as well as a new and fundamental understanding of what it means to be human.

There is no more critical or complex organ in human function than the brain and, at the same time, there is no less understood organ. So there is no more revolutionary and exciting research right now than exploring the brain. Innovations in imaging, genomics, pharmaceutical research, biomedical engineering, and computing are coming together at this extraordinary moment in time to help us understand how 100 billion nerve cells work together."
