%X The cell assembly hypothesis postulates that information processing in the brain entails the repetitive co-activation of groups of neurons [1]. The activation of such assemblies would lead to spatio-temporal spike patterns (STPs) at the resolution of a few milliseconds. In order to test the cell assembly hypothesis, we searched for significant STPs in parallel spike trains, using the SPADE method [2,3]. We analyzed experimental data from the motor cortex (M1/PMd) of macaque monkeys (Macaca mulatta) performing a reach-to-grasp task [4] and found an abundance of STPs. Quantitative analysis showed that STPs are functionally related to behavior, which suggests the presence of assemblies activated during the task.References:[1] Hebb, D. O. (1949).
