Lotus love warmth. If you pull your lotus container out of the pond and place it in full sun in the spring (after frost danger is over), the lotus will grow faster because it will warm up more. Keep some water over the soil, and return it to the pond by early summer, once warm weather is here to stay.
The cerebral cortex is the layer of the brain often referred to as gray matter. The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.
For the journal of a similar name, see Cortex (journal). The cerebral cortex is a brain structure in vertebrates, including humans. It is the outermost layer of the cerebrum and has a grey color.(Hence the name grey matter.n the higher animals (especially the higher mammals), the surface of the cerebral cortex becomes folded. This creates grooves on the surface of the brain called  sulci  (singular = sulcus). The bumps or ridges on the surface of the brain are called gyri (singular = gyrus).
