We have analyzed murine whole cortex time-series RNA-Seq, ATAC-Seq and Histone ChIP-Seq datasets from ENCODE consortia spanning 9 time-points between E11 and Adult. Using these data, we have performed time-series analyses to capture temporal patterns of gene expression, chromatin accessibility and histone enrichment across forebrain development. We have also "footprinted" for transcription factors to capture genome-wide patterns of binding across forebrain development. We have supplied these data in an interactive format allowing users to retrieve regulatory information for any genes/TFs of interest either genome-wide or within the context of axon growth.
