Electrical experiments with plants that count and communicate

| We're alive and conscious, humans! |
Neuroscientist Greg Gage takes sophisticated equipment used to study the human brain out of college-level labs and brings them to middle- and high-school classrooms (and the TED stage).
Prepare to be amazed as he hooks up the Mimosa pudica, a plant whose leaves shut when touched, and the Venus flytrap -- that clamps to catch its prey -- to an EKG machine to show us how plants use electrical signals to convey information, prompt movement, and count.
