The hippocampus is a brain structure important for diverse functions including learning, memory, stress and cognition. The classical tri-synaptic connections are the core circuit in the hippocampus. Yet, there are many other intra-hippocampal circuits that are less known. First, I will talk about the functional role of CA1-Subiculum circuit in temporal associative learning and discuss our hypothesis for the stimulus information maintenance during the learning. Second, I will show our recent single-neuron projectome analysis for hippocampal neurons and their spatial organization principles. Finally, I will show such new projection patterns derived from projectome analysis can be combined with circuit tracing and functional studies to help us to understand the function of an intra-hippocampal circuit linking dorsal and ventral hippocampus.
