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.
Cerebrum is the largest and the most prominent part of the brain, whereas the cerebral cortex is the outer layer of the cerebrum. Cerebral cortex is actually a part of the cerebrum. The human cerebral cortex is actually made up of approximately 10 billion nerve cell bodies and their dendrites, whereas the cerebrum has both cell bodies and nerve fibers. The cerebrum has both gray and white matter, whereas the gray matter is considered to be the cerebral cortex.
