Abstract:
Relatively few genes (approximately 100) have previously been shown to be imprinted such that their expression in progeny derives from either the maternal or paternal copy. Two recent studies by Gregg et al. (2010a, 2010b) in Science expand this list by an order of magnitude, revealing complex patterns of parent-of-origin bias in gene expression in the brain that are developmentally and regionally restricted, and in many cases, sexually dimorphic.

Genomic Imprinting and Inheritance
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
Brain Imaging
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
