Introduction
I'm a postdoctoral researcher and medical doctor at the Charité-Universitätsmedizin. I investigate spatial memory consolidation in healthy humans and humans with hippocampal dysfunction using virtual reality and real-life experimental settings. Previously, I examined the influence of lifestyle-interventions on hippocampal neurogenesis and spatial memory in young adult mice.

Article
Full-text available
Successful navigation to spatial locations relies on lasting memories from previous experiences. Spatial navigation undergoes profound maturational changes during childhood. It is unclear how well children can consolidate navigation-based spatial memories and if age-related variations in navigation during training predict spatial memory. The presen...
Article
Full-text available
Efficient navigation is supported by a cognitive map of space. The hippocampus plays a key role for this map by linking multimodal sensory information with spatial memory representations. However, in human navigation studies, the full range of sensory information is often unavailable due to the stationarity of experimental setups. We investigated t...

Background Previous studies have yielded inconsistent results about hippocampal involvement in non-demented patients with amyotrophic lateral sclerosis (ALS). We hypothesized that testing of memory-guided spatial navigation i.e., a highly hippocampus-dependent behaviour, might reveal behavioural correlates of hippocampal dysfunction in non-demented...
Article
Full-text available
Memory consolidation is a continuous transformative process between encoding and retrieval of mental representations. Recent research has shown that neural activity immediately after encoding is particularly associated with later successful retrieval. It is currently unclear whether post-encoding neural activity makes a distinct and causal contribu...

Spatial navigation is a complex multisensory process that requires the integration of visual, somatosensory and vestibular input and re-afferents from the motor system with mnemonic representations of the environment. Despite this complexity, most human adaptations of the Morris water maze (MWM, Morris et al., 1982) in spatial navigation studies ar...
Preprint
Full-text available
We investigated the role of the post-encoding period for consolidation of self-centered (egocentric) and world-centered (allocentric) spatial memory in neurologically normal human subjects. We used the GABA A -ergic anesthetic propofol to transiently modulate neural activity during the early stage of spatial memory consolidation. A total of 52 pati...
Article
The neurodegenerative disorder Parkinson's disease affects motor abilities as well as cognition. The gold standard therapy is L-Dopa, which mainly restores motor skills. Therefore, we require additional interventions to sustain cognitive functions in Parkinson's disease. The lifestyle intervention “physical activity” improves adult hippocampal neur...
Article
Frequent flyers and shift workers undergo circadian dysrhythmia with adverse impact on body and mind. The circadian rhythm disorder "jet lag" disturbs hippocampal neurogenesis and spatial cognition, which represent morphological and functional adult brain plasticity. This raises the question if pro-neurogenic stimuli might prevent those consequence...

Cancer is a disease of the genome caused by oncogene activation and tumor suppressor gene inhibition. Deep sequencing studies including large consortia such as TCGA and ICGC identified numerous tumor-specific mutations not only in protein-coding sequences but also in non-coding sequences. Although 98% of the genome is not translated into proteins,...

In the context of television consumption and its opportunity costs the question arises how far experiencing mere representations of the outer world would have the same neural and cognitive consequences than actively interacting with that environment. Here we demonstrate that physical interaction and direct exposition are essential for the beneficia...
Article
Full-text available
Immune mechanisms are included in stroke pathophysiologic factors, but the frequency and role of intrathecal antibodies is unclear and diagnostic tests are not routinely performed on cerebrospinal fluid (CSF). To determine the frequency of intrathecal immunoglobulin synthesis in a well-characterized cohort of patients who experienced “noninflammato...
