The sensation of pain occurs when neural pathways conduct excitation generated by tissue damage to the spinal cord, where the nociceptive information is extensively pre-processed. From there, the information is transmitted ...

While fish, reptiles and even some birds can regenerate damaged brain, eye and spinal cord cells, mammals cannot. For the first time, non-neuronal cells have been induced to mimic specific ganglion cells in the eyes of mice.

The human organism contains hundreds of distinct cell types that often differ from their neighbours in shape and function. To acquire and maintain its characteristic features, each cell type must express a unique subset of ...

The brain is typically depicted as a complex web of neurons sending and receiving messages. But neurons only make up half of the human brain. The other half—roughly 85 billion cells—are non-neuronal cells called glia.
