*****Deadline fast approaching for NMC 4!***** After three conferences in 2020, Neuromatch is pleased to be holding our fourth on December 1-2, 2021. Neuromatch 4.0 will be focused on Computational Neuroscience and will be similar to the scope of the first two NMC events in spring 2020. Agendas from previous NMC editions (1.0, 2.0 and 3.0) can be found on the Agenda from the conference website under the gear icon. The scope of NMC4 includes computational neuroscience and machine learning work that has a biological link. Registration costs are set at 15USD to cover technical costs, and if this is a difficulty, the fee can be waived without question. Each of our conferences has led the way in providing new innovations to the virtual conference space, and this year we are excited to offer you: * A combination of the virtual with the in-person conference experiences. You are encouraged to host or attend a local meetup, bringing people together to enjoy the conference, without the incredible economic and environmental costs of flying around the world. * The maintalks will be hosted on Crowdcast. Instead of posters, we offer flash talks (brief pre-recorded videos), and dedicated meet up times for discussion within Discord. * NMC for kids: a special session of talks for a younger audience and the young at heart interested in neuroscience. * We are developing new mechanisms to connect talks in the conference to corresponding preprints on bioRxiv, and we will provide links to preprints on other platforms as well.
