Data and Jupyter/IPython notebooks to examine enriched transcripts in the SCN via Meta-analysis.
The suprachiasmatic nuclei (SCN) in the brain represents the master circadian pacemaker in mammals. It controls the timing of many aspects of physiology and behaviour, as well as coordinating other peripheral clocks in organs throughout the body.
The expression of genes in SCN has often focused on the identification of rhythmically expressed genes. A different approach is taken here: to look at those selectively enriched in the SCN, by comparing the transcriptome of the SCN to that of the brain in general. This will help to find genes that play key roles in SCN physiology or may refine SCN-specific drivers.

An open and low-cost option for monitoring actigraphy and estimating sleep in mice
This project represents our attempt to provide an affordable and non-invasive method to assess activity and (by immobility) sleep in laboratory mice. The publication in Wellcome Open Research describes some of the many options for data collection and analysis.
