Neurons growing in a cell culture These time lapse animations use phase contrast microscopy to show neural stem cells in a nutrient medium for 4 hours. They reveal the dynamic growth and recycling of dendrites and synapses as neurons establish relationships with each other. The social behavior of these cells creates the incredible properties of the mind and brain.
