Dean BUONOMANO, professor of psychology and neurobiology at the University of California, Los Angeles (UCLA)

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.

news-3966 Fri, 29 Sep 2023 11:00:00 +0200 A predictive-processing account of psychosis A conference by Philipp Sterzer, University of Basel Abstract: There has been an increasing interest in the neurocomputational mechanisms underlying psychotic disorders in recent years. One promising approach is based on the theoretical framework of predictive processing, which proposes that inferences regarding the state of the world are made by combining prior beliefs with sensory signals. Delusions and hallucinations are the core symptoms of psychosis and often co-occur. Yet, different predictive-processing alterations have been proposed for these two symptom dimensions, according to which the relative weighting of prior beliefs in perceptual inference is decreased or increased, respectively. I will present recent behavioural, neuroimaging, and computational work that investigated perceptual inference to elucidate the changes in predictive processing that may give rise to psychotic experiences. Based on the empirical findings presented, I will provide a more nuanced predictive-processing account that suggests a common mechanism for delusions and hallucinations at low levels of the predictive-processing hierarchy, but still has the potential to reconcile apparently contradictory findings in the literature. This account may help to understand the heterogeneity of psychotic phenomenology and explain changes in symptomatology over time.

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.

How different complex features of the dynamics emerge from a given structural connectivity (SC) is of great interest for our understanding of brain function, in health and disease. Among the complex dynamical features that are commonly described, the continuously evolving correlation patterns of the brain (Functional Connectivity Dynamics, FCD) has been extensively characterized and described as a marker for aging and psychiatric disorders. More recently, the existence of high-order interdependencies of either synergistic or redundant types has also been shown to change with aging, with brain activity from older healthy subjects showing more redundancy. To understand how different topological features of the structural connectome can be related to these features of the functional connectivity, we built a set of 240-node structural connectomes with varying degrees of integration and segregation, assessed with metrics from network analysis. These connectomes included artificial networks such as Watts-Strogatz or modular networks, and empirical human connectomes that were perturbed to manipulate their integration and segregation measures. The set of over 40 SCs spanned a broad range of the small-world coefficient omega, sweeping from lattice-like to small-world to random-like networks. Then the SCs were used to simulate neural activity using a Wilson-Cowan model modified with homeostatic inhibitory plasticity, to ensure an oscillatory regime over a wide range of the global connectivity parameter G. Then, the simulated activity was assessed for the FCD, using the variance of the FCD matrix as an index for dynamical richness, and for the emergence of synergistic interdependencies, by randomly sampling groups of 3, 4, or 5 nodes. The nature of the high-order dependencies was assessed using the O-information metric, that is negative for systems dominated by synergy and positive for those with more redundancy. In all the networks, the higher variance of FCD and the most synergistic n-plets were found at an intermediate value of G, were the metastability is also high and the network synchrony is moderate. When looking at the structural features, the networks that maximized both complex dynamical features were those having a positive omega index but close to zero. This indicates networks of the small-world type, which have a balance between their integration and segregation metrics. Our results are in agreement with what has been observed in the brain SC and its dynamics as the brain ages.

The Scheiffele group uses an in vivo cell biology approach to uncover mechanisms of neuronal network formation in health and disease. They are seeking to understand molecular mechanisms of synapses formation, developmental remodeling, and plasticity. They apply a broad range of molecular, anatomical, imaging, electrophysiological, and behavioral assessments in rodents. A particular focus is on mRNA alternative splicing and translation, and its dysregulation in autism spectrum disorders. Based on the insights in developmental studies, the Scheiffele lab is developing therapeutic strategies using small molecules and splicing therapeutics for genetically-defined neurodevelopmental conditions.
