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.
The brain cortex or cerebral cortex is the part of the brain which is responsible for higher thought and function. When people think of the brain, they usually visualize images they have seen of the cerebral cortex, since it is the largest part of the brain, and it is the area of the brain which differentiates humans from other animals.
