Learning, Inference & Memory
Athena Akrami's lab at Sainsbury Wellcome Centre, UCL, London
Finding and exploiting patterns and regularities in the environment is a critical brain function for animals living in a complex yet structured world. Individuals can deduce abstract relations, and learn these regularities through experience, and use this prior information to guide future behaviour. The process of inferring statistical patterns and priors constitutes the foundation of further cognitive abilities. How do animals infer these patterns and relations, and how priors are formed, represented, and stored?
Our past, present, and future are intimately linked by our memories of various timescales. The brain is constantly engaged in storing new memories and executing actions while integrating incoming sensory input with past memories and internal models of the world. What are the fundamental principles of (sensory) memory organization, and their utilization in inference problems? How are learned priors integrated in memory, or used in combination with new sensory information?
At LIM Lab we employ a synergistic combination of theory and experiment to tackle the fundamental principles of neuronal computations underlying sensory memory organization and sensory inference. We use high-throughput training to combine sophisticated, well-controlled and quantifiable behavioral paradigms with powerful tools to monitor and manipulate neural circuits. In all of our research programs, experiments are intertwined with hypotheses drawn from theoretical investigations and computational models.
We are hiring!
We have recently received a Consolidator Grant by the European Research Council (ERC) to investigate statistical learning in rats, mice and humans!
The award of €2 million over five years will enable us to continue to pursue our long-term research endeavours on statistical learning and its interaction with working memory. The funding will allow the recruitment of postdoctoral fellows as well as research technicians for up to five years. Please get in touch if you are interested in joining our lab!
