"It appears these neurons help animals – including humans – work out the relative distance between two points by mapping the space between them as a series of grid cells. In effect, we use these grid-cell neurons to work out the gap between things, and thus our position in the world around us."
Ha ha, a bit like many of the local pavements use square paving slabs almost always aligned square to the road and along the direction of travel. Though rarely, if ever, aligned in a flat even plane.
re humans and directions.
Only the other day a guy asked me if i could give him directions to Bradford ( why on earth anyone would choose to go there is beyond me).
Yeah, sure i could, but if i were going to go to Bradford i certainly wouldn't be starting from here.
