During my researches on sleep spindles and their correlates, I encountered many methodological difficulties that seem to plague this field of investigation. I concluded that a concerted effort is needed for overcoming these difficulties and accelerating the pace of discoveries in this area. Along this line, I am preparing a research proposal on the topic of improving spindle analysis methodology. A proposal for a Frontiers Research Topic has also been submitted on this topic to provide a discussion forum for all experts interested by the study of sleep spindle (invitations to contribute will be sent but those not receiving such an invitation can contact me (Christian.firstname.lastname@example.org
) and I’ll send them one). To fuel this topic I invite everyone investigating sleep spindles correlates to share what they think are the most limiting methodological problems regarding sleep spindle studies, what are the technical/methodological problems that they would like to see being solved for their research to produce better results. I start this Q&A by providing some limitations I noted:
• A fuzzy definition (variable frequency range from studies to studies, one ore more spindle classes [slow, fast, ultra-fast, …], etc.);
• Unaivalability of an automatic detection algorithm that is commonly aggred upon;
• Unavailability of a large, high-quality, reference polysomnographic database.
