AC1: Neurobiology of Self and Embodiment


Due to illness, this course had to be canceled!

1. Session: Structural and functional Plasticity in neuronal networks.
2. Rhythms of the brain and their functional role in information processing
3. Imaging of memory traces in the rodent brain
4. Optogenetic manipulations of neurons and thoughts

Our daily life depends on the processing and storing of a continuous stream of information which enables us to rapidly adapt our behaviour to changes of our environment. Current theories of memory formation suggest that experience-dependent modifications in the balance between excitation and inhibition enable a selected group of neurons to form a new cell association during the learning process which represents the newly formed memory trace, the engram. The functional and structural changes at the level of synapses, single cells and cell populations that are associated with the learning process are, however, largely unknown. This is a crucial issue because impaired memory is a leading global problem implicated in various diseases including posttraumatic stress disorder, anxiety and depression, and can have various causes such as stress, sleep deficit or medication. In order to be able to effectively treat memory disorders, we need first to understand how new memories are formed in the central nervous system. In the proposed course we aim to address this fundamental question on the rodent brain particularly to the hippocampus, functionally vital for the acquisition of new memories. I will highlight recent advances in neuroscience shedding light on measurements and manipulations of defined neuronal populations and obtainment of potential memory traces during behavior.


Objective 1: understand the spatial and temporal emergence of learning-related cell associations representing new memories, and,
Objective 2: delineate the nature and relevance of major functional (cellular, synaptic, plasticity) and structural changes underlying the formation of active cell associations.
