The brain is the most complex information processing system that enables us to feel, act, learn and remember, to process and store information with an efficiency and flexibility that by far surpasses any machine. At the same time, dysfunctions of the brain cause a number of devastating cognitive disorders.<\/h5>\n
All cognitive functions depend on the cortex, the largest and most powerful region of the mammalian brain. Looking at neurons it comprises ~80% excitatory principal neurons (PNs) but also a smaller but highly diverse class of GABAergic inhibitory interneurons. PNs represent information at the single cell level (\u2018single neuron code\u2019) or population level (\u2018population code\u2019). However, their activity is markedly shaped by the GABAergic inhibitory interneurons. Interneurons come with distinct morphologies, molecular and synaptic properties, connectivities and activity profiles and may thereby endow the network with a large number of distinct control points for tuning cortical codes according to dynamically changing computational demands.<\/h5>\n
Using mouse models for genetic circuit dissection and human tissue we will focus on a number of cortical areas that are vital for higher brain functions. By combining state-of-the-art optical and electrical recordings with pharmaco- and optogenetic perturbation, quantitative behavior, computational modeling, modern tools for high-dimensional data analysis and deep learning, this CRC\/TRR will provide multidisciplinary insights on the role of inhibition in controlling the encoding of information in local circuits and complex brain functions and thereby shaping the cortical population code.<\/h5>\n
IN-CODE is a Transregio (TRR), a Collaborative Research Centre (CRC) located at multiple sites. TRR\/CRC-384 is located in Freiburg and Berlin, and collaborations between the two cities are actively promoted. The selected PhD students will enrol in the local graduate schools, SGBM (Spemann graduate school of Biology and Medicine) and ECN (Einstein Center for Neurosciences), respectively, and will have access to the qualification program offered by the entire network.<\/h5>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

Role of dentate gyrus GABAergic interneuron types in long-term information encoding by principal cells <\/strong><\/p>\n

Here we aim to examine how interneuron (IN) types contribute to high spatial map stability in the mouse dentate gyrus (DG). To address this question, we will perform 2- \/ 3-photon calcium imaging<\/u> of neuron populations in head-fixed mice navigating through virtual realities. We will apply pharmaco<\/u>-\/optogenetic<\/u> tools to modulate IN type activity to examine its influence on population activity and behavior. By performing deca-patch recordings in acute slices, we will examine the underlying structural-functional microcircuit organization. By using artificial intelligence algorithms, we will uncover how INs contribute to internal structure of active networks & encoding of behavioural variables at the level of population codes.<\/p>\n

Modulation of cortical inhibition by transcranial magnetic stimulation in rodents and humans \u2013 network effects and molecular mechanisms\u00a0 <\/strong><\/p>\n

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique, which modulates cortical excitability beyond the stimulation period. Despite its clinical use it remains unclear if and how TMS mediates changes in synaptic transmission, neuronal excitability, and network activity. We investigate network effects and the underlying molecular mechanisms of TMS protocols in cortical circuits of mice and humans, focusing on parvalbumin-expressing basket cells and somatostatin-expressing dendritic inhibitory interneurons. Our major goal is to identify the cellular and molecular mechanisms of clinically approved TMS on interneuron function and plasticity.<\/p>\n<\/div><\/div>

Inhibitory control of thermal perception in mouse posterior insular cortex <\/strong><\/p>\n

We hypothesis that inhibitory interneurons (INs) in the posterior insular cortex (pIC) are key players in the encoding and perception of thermotactile information. Here we will examine the role of different IN types in sensory encoding and determine how their function is related to underlying synaptic connectivity. We have two aims: (1) use widefield and cellular imaging to identify the thermotactile encoding schemes by pIC INs and test their role in perception using optogenetic manipulations; (2) combine in vivo<\/em> imaging with in vitro<\/em> cortical slice work to delineate the local pIC synaptic wiring motifs in cells of known sensory response properties.<\/p>\n<\/div><\/div>

Neuronal networks store and process information by the local structural and functional connectivity of excitatory and inhibitory neurons.\u00a0 In this project we plan to investigate how fast-spiking inhibitory interneurons are embedded in cortical subnetworks with structural and functional features tailored for specific region and species-dependent computational requirements.<\/p>\n<\/div><\/div>

\u00a0<\/strong>Role of microglia-interneuron interactions in shaping network function<\/strong><\/p>\n

In this project, we aim to explore the role of bidirectional communication between microglia and parvalbumin-positive interneurons (PVIs) in the hippocampal CA1 region. We will test the hypothesis that microglial regulation of PVI activity modulates gamma frequency oscillations that critically depend on PVI function. This will be tested in wild-type and DISC1 mice, which serve as a model system of impaired PVI and gamma function. Using a combination of in vivo and ex vivo electrophysiology, multi-photon imaging and biochemical analyses, we aim to identify the impact of microglia-PVI interactions for microcircuit function and to reveal how microglial dysfunction relates to oscillatory network defects.<\/p>\n<\/div><\/div>
