Three-dimensional functional magnetic resonance imaging of human brain on a clinical 1.5-T scanner.

Functional magnetic resonance imaging (fMRI) is a tool for mapping brain function that utilizes neuronal activity-induced changes in blood oxygenation. An efficient three-dimensional fMRI method is presented for imaging brain activity on conventional, widely available, 1.5-T scanners, without additional hardware. This approach uses large magnetic susceptibility weighting based on the echo-shifting principle combined with multiple gradient echoes per excitation. Motor stimulation, induced by self-paced finger tapping, reliably produced significant signal increase in the hand region of the contralateral primary motor cortex in every subject tested.

Alphabetical catalog of Harvard College graduates through 1767, 1767

This hard-bound manuscript catalog alphabetically lists the men who graduated from Harvard College between 1642 and 1767. It is believed to be the first such list compiled. Entries contain each graduate's surname (in English), given name (in Latin), year of graduation, and occasional additional information. Francis Foxcroft (A.B. 1712) compiled the catalog. Entries for those who graduated between 1764 and 1767 have been added at the end of each alphabetical section.
