Although recent neuronal-network models capture many qualitative aspects of M1 dynamics, they can generate only a few distinct movements. Additionally, it is unclear how M1 efficiently controls movements over a wide range of shapes and speeds. We demonstrate that modulation of neuronal input–output gains in recurrent neuronal-network models with a fixed architecture can dramatically reorganize neuronal activity and thus downstream muscle outputs. Consistent with the observation of diffuse neuromodulatory projections to M1, a relatively small number of modulatory control units provide sufficient flexibility to adjust high-dimensional network activity using a simple reward-based learning rule. Furthermore, it is possible to assemble novel movements from previously learned primitives, and one can separately change movement speed while preserving movement shape. Our results provide a new perspective on the role of modulatory systems in controlling recurrent cortical activity."}],"publisher":"Springer Nature","issue":"12","external_id":{"pmid":["30482949"]},"volume":21,"_id":"8073","doi":"10.1038/s41593-018-0276-0","author":[{"first_name":"Jake P.","full_name":"Stroud, Jake P.","last_name":"Stroud"},{"last_name":"Porter","full_name":"Porter, Mason A.","first_name":"Mason A."},{"first_name":"Guillaume","full_name":"Hennequin, Guillaume","last_name":"Hennequin"},{"id":"CB6FF8D2-008F-11EA-8E08-2637E6697425","orcid":"0000-0003-3295-6181","last_name":"Vogels","full_name":"Vogels, Tim P","first_name":"Tim P"}],"pmid":1,"publication":"Nature Neuroscience","publication_status":"published","day":"01","date_published":"2018-12-01T00:00:00Z","page":"1774-1783","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6276991/","open_access":"1"}],"oa":1,"quality_controlled":"1","language":[{"iso":"eng"}],"related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1038/s41593-018-0307-x"}]},"intvolume":" 21"}
