Memory formation in hippocampal microcircuit

The centre of memory is the medial temporal lobe (MTL) and especially the hippocampus. In our research, a more flexible brain-inspired computational microcircuit of the CA1 region of the mammalian hippocampus was upgraded and used to examine how information retrieval could be affected under different conditions. Six models (1-6) were created by modulating different excitatory and inhibitory pathways. The results showed that the increase in the strength of the feedforward excitation was the most effective way to recall memories. In other words, that allows the system to access stored memories more accurately.

What is hippocampal sclerosis? A cell-type specific perspective

Temporal lobe epilepsy is considered a neuronal microcircuit dysfunction, yet mechanisms are poorly understood. Here we will discuss recent data on cell-type specific alterations of hippocampal microcircuit function in experimental models of temporal lobe epilepsy. We will highlight the importance of leveraging on cellular heterogeneity to better understand the complexities accompanying hippocampal sclerosis.
