Synaptopathy, circuitopathy and the computational biology of Huntington’s disease

Huntington's disease (HD) is one of the most common tandem repeat disorders and presents as a unique trilogy of cognitive, psychiatric and motor symptoms. One of the major mysteries of HD is why it selectively affects specific neuronal populations. A new article in BMC Biology provides a piece in the puzzle of pathogenesis. By demonstrating the delicate relationship between cortical and striatal neurons, it provokes broader questions of how we might understand HD as a disorder of synapses, neural circuits and systems biology.
