Following injection, the rats were monitored to analyze the result of the injection on thermal discomfort perception. Tail-flick withdrawal latencies to noxious heat were used to judge pain perception.

The embryos they studied were barely 24-hours aged and a millimeter long, but neurons within their spinal cord had been forming connections called synapses already. Images were taken every 30 secs over two hours. If we zoom out a little bit and look at development in the human, nearly all synapse formation happens in the cortex after birth and proceeds for the first two years in a baby's lifestyle, said Philip Washbourne, a professor of biology and member of the UO's Institute of Neuroscience.
