We are pleased to announce the creation of "Mathematical Neuroscience and Applications". The aim of this new journal is to publish the best work in mathematical neuroscience and its applications and making it broadly available to the scientific community in a completely open fashion, i.e. at no costs for readers and authors (no APCs). The webpage of the journal can be found at https://mna.episciences.org/ <https://secure-web.cisco.com/1Th57tM0Q4wnQK5WU9a83gEk5eiepY75pxIXyIVdMZmATN0...> where more information such as how to submit an article, or the list of Editorial Board Members, https://mna.episciences.org/review/staff <https://secure-web.cisco.com/1CXJhkD3WpGFVRfTHEqp6vfR8XHQDkEeIIbSjzi2e5bXzhQ...> , is available. This is the Diamond Open Access model which is made possible in our case thanks to the support of Episciences, https://www.episciences.org/# <https://secure-web.cisco.com/1EwusptV_q2y1ZQTKNt9O1K0__jJocYNjvm6c6ar0ARXwJW...> Editorial Board Members of MNA are looking forward to publishing your work.
