Next, these mPFC mean beta weights from the self-generated versus externally presented comparison that were extracted across the
a priori spherical mPFC ROI for each group selleck at 16 weeks were correlated with behavioral performance for each group at 16 weeks. See Figure S1 and Table S1 for whole brain analyses of the self-generated condition versus the externally presented condition at baseline in (A) HC and (B) SZ subjects, and see Figure S2 and Table S2 for whole-brain signal change at 16 weeks versus baseline in (A) SZ-AT, (B) SZ-CG, and (C) HC subjects.

“The human brain sets us apart from other animals because of its large size and extraordinary intellectual capability. The last two million years have seen a rapid enlargement of the hominin brain, achieving
in modern humans a size about three times larger than that of chimpanzees (Pan troglodytes) and over ten times the size of the brain of the rhesus monkey, Macaca mulatta. In particular, the human frontal cortex, which is thought to be involved in higher mental functions, is disproportionately enlarged compared to lesser apes and monkeys, but not to other great apes ( Semendeferi et al., 2002). Explaining the evolution of these size and cognitive differences among primates has preoccupied neuroscientists over many decades and has begun to catch the attention of genome biologists. why Comparative neuroanatomy and comparative genomics have recently joined forces in a quest to explain brain evolution in terms of differences in the transcriptional activity of particular genes. The contribution from Konopka et al. (2012) in this issue of Neuron is thus part of a growing body of work that seeks to define which brain regions, and which genes, have contributed most to human cognition. In pursuit of this quest, neuroscientists and genome biologists alike will have to distinguish from among many anatomical and DNA sequence changes the few that underlie the ascendancy of the human brain.
