520 _ _ |a The cell assembly hypothesis postulates that information processing in the brain entails therepetitive co-activation of groups of neurons [1]. The activation of such assemblies wouldlead to spatio-temporal spike patterns (STPs) at the resolution of a few milliseconds. In orderto test the cell assembly hypothesis, we searched for significant STPs in parallel spike trains,and developed the SPADE method [2,3]. Using SPADE, we analyzed experimental data fromthe motor cortex (M1/PMd) of macaque monkeys (Macaca mulatta) performing areach-to-grasp task [4] and found an abundance of STPs. Quantitative analysis showed thatSTPs are functionally related to behavior, which suggests the presence of assembliesactivated during the task.References:[1] Hebb, D. O. (1949).
