The ability to tell time, represent and encode temporal information, and use past experiences to predict the future, are among the most fundamental computations the brain performs. But how do networks of neurons tell time and encode temporal information in a flexible manner? Precisely because of the importance of time, we argue that most neural circuits are capable of temporal computations. But in contrast to the clocks on our wrists that rely on the same mechanism to tell time across a wide range of scales, the brain engages many different mechanisms and circuits to tell time. We and others have proposed that on the scale of seconds timing relies on neural population clocks: time-varying patterns of neural activity that emerge from the dynamics of recurrent neural circuits. More generally, we propose that such dynamic regimes represent a fundamental computational strategy in the brain.

We study the contribution of microglial cells and underlying mechanisms of neuronal and glial dyshomeostasis in neurodegenerative conditions including Alzheimer´s disease (AD) and the childhood dementia Niemann-Pick type C (NPC). We use translational approaches to identify molecular fingerprints of microglial dysfunction and identify novel cellular targets to target and monitor neuroinflammation across neurodegenerative disorders.

Our research aims to explore the intricate interactions between Müller cells, microglia and neurons in both healthy and diseased retinas. We are particularly interested in understanding the effects of AAV-vectored gene therapies targeting these interactions, in particular the coordination of the retinal immune response, for example by modulating retinal complement homeostasis or glucocorticoid receptor signaling. We demonstrate that our approach of delivering therapeutic gene expression to Müller cells can improve disease progression in models of diabetic retinopathy or ischemic stress, independent of the underlying cause of the disease, and thus may benefit patients who are not candidates for currently available treatment strategies, since most, if not all, retinal diseases involve Müller cell gliosis and inflammatory processes that potentially accelerate neuronal dysfunction.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease of the adult motor system, for which effective treatments remain elusive. Mutations leading to the mislocalization of FUS, an essential RNA-binding protein, have been linked to the most severe form of ALS. Despite intense research efforts, the cascade of pathological events triggering the progressive degeneration of motor neurons remains incompletely understood. Our prior investigations revealed significant lipid metabolism alterations in the spinal cord of a FUS mouse model, as well as in motor neurons derived from ALS patients induced pluripotent stem cells (iPSCs). Recent evidence suggests that dysfunctional glial cells, including oligodendrocytes, contribute to neurodegeneration in FUS-linked ALS through non-cell autonomous mechanisms. In our latest research, we investigated the impact of FUS mutations in oligodendrocyte progenitor cells (OPCs) derived from human iPSCs. Confirming the cytoplasmic mislocalization of FUS in OPCs, we uncovered significant alterations in lipid metabolism, accompanied by transcriptomic alterations related to myelin formation. Additionally, we observed mitochondria-associated ER membrane abnormalities, ER stress, and mitochondrial dysfunctions. These recent findings emphasize the pathological role of FUS in oligodendrocytes, shedding light on the intricate cellular mechanisms contributing to FUS-linked ALS pathology.

Bio: Philipp Sterzer is a psychiatrist, neurologist and neuroscientist who trained in Frankfurt am Main, London and Berlin and held a professorship for psychiatry and computational neuroscience at Charité Berlin from 2011 to 2022. Recently, he was appointed Professor of Translational Psychiatry at University of Basel, Switzerland. His work focuses on the investigation of predictive neural processes in perception and their alterations in psychotic disorders using functional neuroimaging and computational modeling among other methods. Along with numerous articles in scientific journals and textbooks, he recently published “Die Illusion der Vernunft”, a popular science book on delusions and other irrational beliefs.
