Slicing Brains Very Quickly - Todd Huffman

Video: http://ignitephoenix.blip.tv/file/1839013/

Event: Ignite Phoenix 3 @ TCA
Event Date: February 25th, 2009

I’ve been an entrepreneur for the last few years, but I’d like to tell you about my real passion in life — slicing brains into very thin slices (very quickly), and taking pictures. High-throughput quantitative analysis of neural morphology and connectivity enables awesome insights into human thought. I’ll show lots of pretty pictures and tell dazzling stories.
