Fig. 4.

Chromosomal localization of expressed genes in hypothalamus and neocortex. The chromosome display shows in silico chromosome banding (GC-rich, white; GC-poor, black). The bar chart refers to the left axis (dark gray bars above the chromosome represent the hypothalamus, and the light gray bars represent the neocortex), representing the gene expression levels of the two tissue types. The plus (+) symbols refer to the right axis, with each symbol representing the ratio of expressed gene levels contained within a 10-Mb window between the two tissues. The positions of qRT-PCR validated tags/genes (▴) and tags that are differentially expressed between the hypothalamus and neocortex (▵)(P < 0.10, corrected Fisher's exact test) are indicated. Note that the physical positions of cadherin-related neuronal receptor (CNR) and zinc finger-containing (ZNF) gene families are closely linked to predicted gene clusters indicated by the plus symbols.
