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, determining the degree to which patterns can pass. Or can the gate be different for different synapses or signals at the same time? In this case, there would be more like a vector of degrees for all individual synapses of the gated nerve cord.
Is there anything known about this?
