Understanding Brain Predictions with Neurons
47:06 - 53:02 (05:56)
The hippocampus and entorhinal cortex in the brain hold a reference frame for room and environment, allowing for predictions to be made about varying contexts, which could lead to more insight into the prediction capabilities of groups of neurons.

Understanding the prediction mechanism of a single neuron may offer insights into the prediction capabilities of the many brains within the bigger brain.

Summary
Understanding the prediction mechanism of a single neuron may offer insights into the prediction capabilities of the many brains within the bigger brain. When a whole bunch of neurons are in the predictive state, they anticipate becoming active and disable everything else, leading to different representations in the brain for different contextual inputs.

Summary
The 1000 brains theory proposes that the brain is made up of many mini-brains which work together to create perception. The theory was developed by studying the role of prediction in the brain, as every part of the cortex is making predictions.

The cortex needs to understand where the finger is relative to the object to make predictions about how it will feel to touch it, according to neurosurgeon Dr. Eric Leuthardt.

Summary
The cortex needs to understand where the finger is relative to the object to make predictions about how it will feel to touch it, according to neurosurgeon Dr. Eric Leuthardt. This understanding is facilitated by the reference frame for a room or environment found in the hippocampus and entorhinal cortex.
