Cajal Neurons

The thinking neurons In the early 20th century Spanish scientist Santiago Ramón y Cajal known as 'Cajal' drew the first observed neurons as black shapes. The artist paints them here full of colour. Cajal was a talented artist and made extensive studies of neural materials. Neurons or nerve cells are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS) controlling many motor and sensory functions of the body.
