Paper Reviews on Multiscale Representation and Representational Drift in the Neocortex -Jul 12, 2021
Channel: Numenta
Date: 2021-07-16

We reviewed 2 papers in this research meeting. First, Numenta intern Jack Schenkman reviewed the paper “Multiscale representation of very large environments in the hippocampus of flying bats” by Eliav et al. The paper proposes a multiscale neuronal encoding scheme of place cells for spatial perception. The team then raised a few questions and discussed. 

Next, our researcher Ben Cohen reviewed the paper “Representational drift in primary olfactory cortex” by Schoonover et al. The paper shows that single neuron firing rate responses to odor in the anterior piriform core are stable within a day, but continuously drift overtime.  The team then discussed the notion of representational drift in the context of Numenta’s work.

Numenta is leading the new era of machine intelligence. Our deep experience in theoretical neuroscience research has led to tremendous discoveries on how the brain works. We have developed a framework called the Thousand Brains Theory of Intelligence that will be fundamental to advancing the state of artificial intelligence and machine learning. By applying this theory to existing deep learning systems, we are addressing today’s bottlenecks while enabling tomorrow’s applications.
