How does the brain learn, store, and recall specific locations and events? And what causes these memory processes to malfunction in disease?

We study how neural computations on the cellular and circuit level underlie memory guided behavior and cognitive dysfunction.

 

Research topics

  • cracking the neuronal code

    cracking the neuronal code

    We want to understand how hippocampal neurons in the subiculum generate the neuronal code of action potential sequences that is transmitted to other brain regions such as the cortex. This action potential code is densely packed with information on the spatial position, self-motion, motivation, salience and is tuned by prior experience via synaptic plasticity. For cracking this hippocampal output code, we monitor synaptic input of multiple kinds during the behavior. We then use computational modeling to predict the conversion of input to output and finally test our predictions by recording directly from single neurons with synaptic resolution during behavior (supported by ERC consolidator grant SUB-D-Code).

  • using artificial intelligence to detect features in neural activity and behavior

    using artificial intelligence to detect features in neural activity and behavior

    We are using machine vision and learning to classify behavior. The application of artificial intelligence based tools has the potential to revolutionize research on neural correlates of behavior. In particular, we classify the way an animal changes its pose and interacts with an environment in an unsupervised manner. We are convinced that high temporal resolution unsupervised behavioral classification will be a first step allowing us to correlate behavioral features with neural activity patterns. The second step is extracting scientific understanding and detecting causal relationships within these large behavior-correlated neural activity imaging data sets. In other words, we want to understand biological neural networks by using artificial neural networks as a tool.  (supported by EFRE funding, Pavol Bauer, Kevin Luxem, Johannes Kürsch)

     

  • understanding the diversity of neurons

    understanding the diversity of neurons

    For most brain areas a comprehensive understanding of the cell clusters forming the neural circuits is currently absent. In collaboration with Nelson Spruston (HHMI Janelia), Mark Cembrowski (University of Vancouver and the Janelia Quantitative Genomics Unit we use single-cell RNA sequencing and multiplexed in situ hybridization for transcriptomic profiling of cell types. A brain region of highest interest is the medial septum. It is a brain region that controls hippocampal memory circuits. We have set up an innovative framework of bioinformatics analyses to identify genetically-defined cell populations. In combination with viral tracing tools we further reveal specific hippocampus-projecting clusters and dissect their function during behavior (supported by HHMI Janelia Visitor Project) Stefano Pupe

     

  • understanding vulnerability and resilience of neural circuits to cognitive dysfunction

    understanding vulnerability and resilience of neural circuits to cognitive dysfunction

    We are investigating how hippocampal memory circuits and individual neurons within these circuits respond to progressive pathological challenges. Here we have set a focus on the accumulation of amyloid beta, which can be observed in human Alzheimer patients and in advanced physiological aging. We found a computational principle explaining why reduced dendritic size in the response to pathology results in higher neuronal.  By using computational modeling, we could understand how neuronal structural changes define electrical properties of dendrites and entire neurons. On the circuit level, we are investigating how hippocampal inhibitory and excitatory neurons interact in microcircuits and how altered interneuron function contributes to the malfunction of learning and memory processes (supported by SFB 1089 project B01) Liudmila Sosulina, Hiroshi Kaneko

     

  • investigating the subcortical modulation of memory circuits

    investigating the subcortical modulation of memory circuits

    Subcortical areas form the core of our brain, they are involved in complex activities such as memory, emotion, pleasure, arousal and hormone production. They act as hubs by relaying and modulating information passing to different areas of the brain including the hippocampus. We are trying to gain a better understanding on how hippocampal circuits are controlled by direct and indirect subcortical modulation from the medial septum, the locus coeruleus and the ventral tegmental area. The medial septum is a basal forebrain region that is reciprocally connected with the hippocampal formation, where it orchestrates microcircuit activation and oscillatory activity during different behavioral states. It is known as a main source of Acetylcholine, which is released by septo-hippocampal afferents during learning and memory processes. We have discovered that, in addition to cholinergic projections, glutamatergic and GABAergic septo-hippocampal projections play a key role in the control of activity levels of hippocampal neurons during memory guided navigation. The medial septum is an important network hub, it integrates behavioral state dependent input from locus coeruleus and channels specific information to the hippocampus and other memory-relevant brain regions. We want to better understand the multitude of medial septal functions during behavior (supported by SFB 1089 subproject C05) –  Petra Mocellin, Liudmila Sosulina

    New preprint on mechanisms of neuronal hyperexcitability and network dysfunction in Alzheimer’s disease

    Our new paper is out. It ist the result of a great collaboration with Martin Fuhrmann’s (DZNE ) and Michael Rowan’s (Trinity College, Dublin) labs. Liudmila Sosulina and Manuel Mittag analyzed the hippocampal micronetwork in a rat model of AD at an early disease stage at the beginning of extracellular amyloid beta (Aβ) deposition. They are the first to show with two-photon Ca2+-imaging in vivo and patch-clamp physiology that neuronal hyperexcitability can be observed in the hippocampus of rats and is present at very early stages. They show that mechanistically this micronetwork dysfunction is due to changes of intrinsic neuronal excitability, rather than reduced inhibitory synaptic transmission, which sets in at later stages. Our data support the view that altered intrinsic excitability of CA1 neurons may precede inhibitory dysfunction at an early stage of disease progression.

     

    Release of new preprint including research code

    We are excited to share a new preprint entitled “Identifying Behavioral Structure from Deep Variational Embeddings of Animal Motion” that is available at BioRxiv.

    In this work we present a novel machine learning framework for discovery of the latent structure of animal behavior given data from markerless pose estimation entitled Variational Animal Motion Embedding (VAME). VAME clusters the time series data into “behavioral motifs”, which are stereotypical behavioral patterns that occur repeatedly in free behavior. The structure of behavior is then represented in the distribution of motifs and the probability of transitions between them. In the preprint we show that this information is sensitive enough to serve as a basis for classification of mice according to its behavior phenotypes. This can be done even for subtle behavioral differences, which human experts are unable to detect from the video capture.

Within the department biologists, mathematicians and computer scientists collaborate to extract scientific understanding from multidimensional behavioral and neurophysiological data sets.

    He obtained the doctoral degree at the University of Bonn in 2003 and then worked from 2003-2005 as postdoc with Heinz Beck at the Department of Epileptology (Head: Christian E. Elger). As an Alexander-von-Humboldt fellow he joined the Department of Neurobiology and Physiology at Northwestern University, Evanston, in 2005. There he worked with Nelson Spruston on dendritic excitability and synaptic plasticity. In 2007 he continued his postdoctoral training with Heinz Beck in Bonn, where he started his own research group in 2009 funded by the state of NRW. From 2010 he headed a research group at the German Center of Neurodegenerative Diseases Bonn (Head: Pierluigi Nicotera) before moving to Magdeburg in 2020.


    There are places I remember
    All my life though some have changed
    Some forever not for better
    Some have gone and some remain
    All these places have their moments
    With lovers and friends I still can recall
    Some are dead and some are living
    In my life I've loved them all.

    (John Lennon/ Paul McCartney)

     

    My research philosophy is explained here in my inaugural lecture.
