This is what brain cell conversations look like
Call them the neuron whisperers. Researchers are eavesdropping on conversations going on between brain cells in a dish.
Rather than hearing the chatter, they watch neurons that have been genetically modified so that the electrical impulses moving along their branched tendrils cause sparkles of red light (see video). Filming these cells at up to 100,000 frames a second is allowing researchers to analyse their firing in unprecedented detail
