Genomic studies demonstrate that, although the majority of the mammalian genome is transcribed, only about 2% of these transcripts are code for proteins. We investigated how the long, polyadenylated Evf2 noncoding RNA regulates transcription of the homeodomain transcription factors DLX5 and DLX6 in the developing mouse forebrain. We found that, in developing ventral forebrain, Evf2 recruited DLX and MECP2 transcription factors to important DNA regulatory elements in the Dlx5/6 intergenic region and controlled Dlx5, Dlx6 and Gad1 expression through trans and cis-acting mechanisms. Evf2 mouse mutants had reduced numbers of GABAergic interneurons in early postnatal hippocampus and dentate gyrus. Although the numbers of GABAergic interneurons and Gad1 RNA levels returned to normal in Evf2 mutant adult hippocampus, reduced synaptic inhibition occurred. These results suggest that noncoding RNA-dependent balanced gene regulation in embryonic brain is critical for proper formation of GABA-dependent neuronal circuitry in adult brain.

Software tool that detects peaks of any type, any shape, any direction, and any size for neuroscientists who are studying spontaneous activities. Allows detection of virtually any kind of peaks including spontaneous miniature synaptic currents and potentials, action potential spikes, calcium imaging peaks, amperometric peaks, ECG peaks etc. It includes the complex and multiple peak detection algorithm. Has post-detection analyses including essential plots and statistical parameters. Group Analysis provides specialized and detailed analysis options for action potentials, decay fitting, fEPSP/population spikes, amperometry, etc.
