What is it about?
The brain has an ability to identify potentially salient temporal features within a hierarchically organized sequence without supervision. We developed biologically plausible, novel style of network-level computation. The significance of this study resides in that, by incorporating findings in the structure of actual neurons, the neural network learns to gate information transfers in a hierarchically organized manner.

Why is it important?
The brain's ability to learn salient temporal features within a hierarchically organized sequence underlies a wide variety of cognitive functions, including sensory processing, motor learning, memory processing, and language processing in humans and other species. An important feature of the brain's mechanism for segmenting sequence information is its context-dependence in learning. The neural mechanisms underlying this flexible unsupervised learning remain unclear.
