A remarkable feature of the brain is that similar information is invariably represented in several parallel brain areas. It is therefore often unclear whether and how these different areas contribute ...

Neocortical parvalbumin-expressing (PV) neurons critically regulate circuit excitation by strong synaptic inputs onto local pyramidal (Pyr) neurons. Plasticity in PV-mediated inhibition during ...

For this work specifically, Schapiro and colleagues built a neural network model composed of a hippocampus, the brain's center for new memories, tasked with learning the world's day-to-day, episodic ...

The neocortex is the largest and most complex part of the brain and has long been considered the ultimate storage site for long-term memories. But how are traces of past events and experiences laid ...

The neocortex constructs an internal representation of the world, but the underlying circuitry and computational principles remain unclear. Inspired by self-supervised learning algorithms, we propose ...

A new study identifies a region of the thalamus as a key source of signals encoding past experiences in the neocortex. The brain encodes information collected by our senses. However, to perceive our ...

REDWOOD CITY, CA -January 14, 2019 - Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual ...
