eeg-notebooks is a python-based software library that provides a simple end-to-end platform for conducting cognitive neuroscience experiments using consumer-grade EEG technology. It emerged out of the close relationship between our good friends at NeuroTechX and other other good friends at InterAxon (just down the road from CAMH). Using eeg-notebooks together with a standard laptop computer and ~$200 EEG headset such as the Interaxon MUSE, one can conduct high-quality event-related potential (ERP) experiments that traditionally require research-grade equipment costing tens of thousands of dollars.
