Rats Striatum and Robot Algorithm Match

Rats Striatum and Robot Algorithm Match

The firing rate of a single dorsolateral striatum neuron in a rat (top), in the moments just before making a decision to pick the left or right hole, closely matches the trial-varying action value for left (bottom; the expected benefit of picking left estimated from the rat’s choice behavior based on an algorithm). This appears to indicate that the rat’s neurons are performing very similar action value learning as the algorithm used in adaptive robots.

Correlation between connectivity and distance of neurons in the human cortex

This diagram shows correlation between connectivity and distance of neurons in the human cortex. There are approximately 100,000 neurons in a square millimeter of cortex, as illustrated in the center box. The red gradation shows neuronal connectivity, with dark red indicating denser connectivity through synapses. While half of the synapses connect to neurons close to them, the other half connect with distant neurons, as so illustrated in the boxed area on the far left of this diagram. The differences in connectivity and distance between neurons require whole brain simulation in order to understand brain function.
