Functionally, it is a high-level multimodal associational area linking many different types of information, and it is indispensable for remembering personal events (“episodes”) and is important for learning new facts. Its structure is significantly simpler than that of the neocortex, but it is also in many ways (e.g. in terms of its main cell types) similar to other cortical areas, which makes it a popular target for experimental studies. The hippocampus is an evolutionarily conserved, old cortical region. Yet, despite intensive experimental and theoretical studies, the mechanisms through which the hippocampus contributes to these cognitive functions and dysfunctions are poorly understood. The hippocampus ( wikipedia, scholarpedia) is a brain region that is known to play a key role in memory and spatial navigation, and is also heavily involved in brain disorders such as Alzheimer’s disease and epilepsy. The physiological variability of channel density in hippocampal CA1 pyramidal cells and interneurons explored using a unified data-driven modeling workflow.
