Albuquerque - Winter arrived and it got quiet. With the temperature drop, the cold-wusses, with their loud mufflers, decided to stay inside. Traffic is still intense; the latest game being running red lights. I don't go out much.

P.84 - last sentence - Diamond, his mentor, inspired Beau to pursue neuroscience.

Diamond produced the first scientific evidence of anatomical neuroplasticity in the early 1960s. At that time, the scientific consensus was that the nature of your brain was due to genetics and was unchangeable and fixed. Diamond showed that the structural components of the cerebral cortex can be altered by either enriched or impoverished environments at any age, from prenatal to extremely old age. 

Her research team also showed that the dorsal lateral frontal cerebral cortex is bilaterally deficient in the immune deficient mouse and can be reversed with thymic transplants. In humans, cognitive stimulation increases circulating CD4-positive T lymphocytes, supporting the idea that immunity can be voluntarily modulated, in other words, that positive thinking can impact the immune system.^[5]
