Bees are directed to pollen and nectar by the rainbow colours blue green and violet together with invisible ultra-violet patterns. Bees then find their hives by remembering light angles and landmarks from which they have built their navigating map.
If I was a Bee I would revisit flowers I had just left and get lost on my way back to my hive. My Nan gave me the getting lost gene. She and I would come out of a shop and head back the way we had come, only realising when we passed M&S, WH Smiths and Woolworths for the second time!
But it would appear that most! humans have navigation cells called 'Grid Cells' as a Built In GPS.
I wonder if brain tumour cells inhibit 'Grid Cells? Mr H is a homing pigeon. His 'Grid Cells' must be huge, firing away like fireworks on bonfire night. When we spend a day in an unknown town I walk slightly behind to ensure Mr H sniffs out the pollen while I have my head in the clouds.
