Differences along the dorsal and ventral axis of the hippocampus reveal distinct processing characteristics, yet the connectivity patterns of different types of interneurons across hippocampal regions are not well understood. One specific group of interneurons, identified by the Chrna2 gene, known as OLMα2 cells, are noteworthy for their unique properties. These cells have a gate-switching function that regulates memory processes and risk-taking behavior differently across the dorsoventral axis. Using monosynaptic rabies tracing, we investigated how OLMα2 cells are wired in the dorsal, interme

Neuromodulators have a key role in mediating cognitive processes such as attention, learning and memory. Disorders of the neuromodulatory systems underlie certain degenerative neurological conditions like Alzheimer’s and Parkinson’s diseases. While the role of neuromodulators in explicit learning is increasingly in the focus of the research, their participation in implicit learning and memory processes is poorly understood.To examine this we have used a previously developed automated training setup in which animals must respond to sequential light flashes at different locations. Following the
