Mario Dipoppa

The theoretical and computational neuroscience laboratory led by Mario Dipoppa, is dedicated to unraveling the principles underpinning the computations of the cerebral cortex. The cerebral cortex is the seat of high cognitive functions. Despite the astonishing complexity of its operations, the cortex exhibits a consistent structure that likely underlies common canonical functions and computations. Discovering these canonical computations would help us gain a deeper understanding of intelligence in the mammalian brain and shed light on neural disorders. His laboratory addresses fundamental questions that are vital to developing comprehensive theories of canonical computations in the cortex:
- How do cortical dynamics give rise to canonical computations?
- How do biophysical constraints and computational needs shape the properties of cortical circuits?
- How is information represented and transformed across populations of cortical neurons?
To tackle these questions, we employ a multidisciplinary approach that combines data-driven circuit models, biologically realistic deep learning models, abstract neural network models, and machine learning methods to analyze the neural code.
