The Neural Engineering Framework (and the associated software tool Nengo) provide a general method for converting algorithms into neural networks with an adjustable level of biological plausibility. I will give an introduction to this approach, and then focus on recent developments that have shown new insights into how brains represent time and space. This will start with the underlying mathematical formulation of ideal methods for representing continuous time and continuous space, then show how implementing these in neural networks can improve Machine Learning tasks, and finally show how the resulting systems compare to temporal and spatial representations in biological brains.

The Neural Engineering Framework has been used to create a wide variety of biologically realistic brain simulations that are capable of performing simple cognitive tasks (remembering a list, counting, etc.). This includes the largest existing functional brain model. This talk will describe this method, and show some examples of using it to take high-level cognitive algorithms and convert them into a neural network that implements those algorithms. Overall, this approach gives us new ways of thinking about how the brain works and what sorts of algorithms it is capable of performing.
