FDR
#
- False Discovery Rate (Benjamini & Hochberg, 1995) is a relatively new statistical procedure that controls the number of mistakes make when performing multiple hypothesis tests. False Discovery Rate (FDR) accomplishes this task by allowing one to control beforehand, the average fraction of false rejections made out of the total number of rejections performed. Furthermore, the FDR procedure is a simple procedure that can be adapted to work with correlated data sets. (from http://www.unt.edu/benchmarks/archives/2002/april02/rss.htm)

FMRI
#
- Functional MRI - A technique that helps to pinpoint functional areas of the brain. While the MRI is scanning, the patient is asked to perform a series of activities and movements, such as reading a list or tapping fingers. The areas of the brain that correlate to these movements and activities "light up" on the scan and create an image. This information is used by surgical navigation computers in the planning of incisions, skull openings and tumor removal to minimize neurological deficits.
