Brains, neurones and textiles

I have been continuing with my work based on brains, here are a couple of the latest pieces I've made. I like the idea of the neurons spilling out at the edge where the brain isn't sealed but I'm a little disappointed with the end result in shape - this may be says more about the state of my brain than I intended!!

This one is all embroidered but I haven't finished it yet there may be words around it too but I'm not sure. 
I visited the Wellcome Trust brain exhibition last week it was fascinating and inspiring, had to buy the book - too relevant to leave behind!
