Neurons in the brain Credit: Dr Jonathan Clarke. Pyramidal neurons forming a network in the brain. These are nerve cells from the cerebral cortex that have one large apical dendrite and several basal dendrites.
Living neurons firing The micrograph shows living neuronal cells. In a gene-modified procedure different components of the cells are coloured by fluorescent proteins, so that two different structure components, tubulin and actin, obtain different colours.
It's pretty awesome to see an actual neuron and be able to identify it's components A neuron from the hippocampus at magnification. There are approximately 100 billion neurons in the human brain. Image by Dr. Carlo Sala, CNR Institute of Neuroscience
