"teens typically experience a burst of cortical gray matter growth at puberty followed by a wave of gray matter loss extending into their early twenties. teens diagnosed with schizophrenia experience "

loss of gray matter that spreads in waves into their early twenties.

Explanation:

Cortical gray matter is considered as the major components of the brain and spinal cord, that is the central nervous system, which consist the capillaries , glial cells and synapses. These are collectively known as neural tissues.

They are probably referred to gray matter of their gray color.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
