Abstract

• Higher areas make hypotheses to explain lower areas activity
• A generative model turns hypothesis into predictions
• A lower areas compare predictions with inputs
• Residuals from lower areas are sent back to higher areas
• Repeat

EEG#Alpha rhythm $ alpha$

Explanation

Intuition

• A white noise stimulus is unpredictable
• A strong input will cause a strong prediction
• The prediction will most likely be wrong (due to the noise nature)
• It will produce an error signal, aiming to correct in the opposite direction
• The correction will also be wrong, producing an opposite error signal, and so on
• The prediction and the error signals will oscillate, and so will the IRF (Impulse Response Function)
