Is cortical magnification in the visual system related to synaptic pruning, or is it a separate developmental or learning process?

I'm primarily interested in learning about current computational models that explain cortical magnification in the visual system. With this in mind, my specific questions are: (1) Is this phenomenon ...

Do gating mechanisms in the neocortex have individual degrees for all gated connections?

For example, the upward connection between layers in the neocortex flows through the Thalamus which is assumed to have a gating function. I wonder whether there is a single value per gate, ...

Is there evidence of neurons corresponding to the certainty of next input prediction?

I think the levels of the hierarchically structured neocortex try to predict their next input. If so, is there a mechanism of measure of certainty in that prediction? For example a high prediction ...
