Fascinating! The grid cells' ability to map onto 'two dimensional bird space' makes me think that they are potentially capable of adapting to any sort of universe, even if the 'dimensional' parameters sound completely insane to us. If the multiverse theory is correct, this makes me think that grid cells could be a common component in any universe capable of supporting life. Suppose that each dimension has a bi-directional aspect. Backwards/forwards, side to side, up/down, and into the past/future are examples in our universe, but suppose that this duality holds up into all dimensions. Are grid cells then perhaps a 'biological binary' onto which anything could be graphed, regardless of units of measure?

This is very interesting! I'm very excited about the potential for a new treatment. This hits home for me, as I suffer from anxiety, but I also have a cluster of other symptoms (from metabolic issues to inflammation problems) that look like they could potentially be related to Ghrelin. I would love to hear updates on this topic as new information becomes available.
