Scientists are now launching one of the most audacious projects ever conceived: a detailed map of the human brain, neuron by neuron, synapse by synapse. Our brains have close to 100 billion neurons and trillions of synapses, so the job is almost impossibly complicated. For some scientists the goal isn't just to map the brain, it's to crack the mystery of consciousness. In this hour of To the Best of Our Knowledge we'll explore the hidden depths of the brain and meet one of the most remarkable things on earth, the mind of an octopus. We'll also ask you to consider another remarkable thing - your public radio station, as we ask for your support.
