Does the pre-synaptic neuron location in a cortical map influences the spatial position of its synapses in the dendrite of the downstream neuron?

Are functional maps in the cortex used by the brain to carry out computations or are they just a byproduct of wiring minimization? A key element to answer this question is to know if, when...

Is it always better to use friction values in inundation modeling, even when we have high-resolution DEM, where rough surface changes are detailed?

I am aware of computational costs while working with high resolution data, so this question is more of hypotetical nature and is related to the relevance of friction parameter in inundation...
