abstract = {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).
