If you’re in the Philadelphia area, or just traveling through, The Franklin Institute recently opened its largest permanent exhibit, Your Brain, in the new Nicholas and Athena Karabots Pavilion.

From the press release:
With over 70 interactive experiences, the 8,500 square foot Your Brain exhibition will be the largest permanent exhibit at The Franklin Institute, and in the country, dedicated to the most complex and misunderstood vital organ in our bodies. The exploration-driven exhibition will help visitors understand that the brain and the nervous system underlie all human behavior, appreciate that the brain is always changing, and contemplate the potential of our evolving knowledge of the brain to transform ourselves and society.

In the June Report on Progress, Drs. Christie D. Fowler, Brian Lee, and Paul J. Kenny explain the use of two emerging techniques, optogenetics (light) and DREADDs (drugs), to better study how the central nervous system works.
The ability to manipulate the activity of specific subsets of neurons in the brains of living animals is leading to significant new insights into how the central nervous system works. The recently developed yet already well-established approaches of optogenetics and pharmacosynthetics use light or small molecules, respectively, to control the activity of neurons in the brains of laboratory animals. Using these techniques, we can see how distinct groups of neurons contribute to normal behavioral states or to abnormal behavior similar to those associated with neuropsychiatric disorders.

The question of how individual differences in behavior and personality develop—especially in terms of the interaction between genes and the environment—has proved to be a formidable challenge in neuroscience. In “One of a Kind: The Neurobiology of Individuality,” the featured Cerebrum article for June, Richard J. Davidson, Ph.D., impressively summarizes mounting new imaging evidence that suggests brain circuits involved in our emotional responses are highly plastic and change with experience, affecting our disposition. He also points to new research that suggests that psychological interventions can further harness brain plasticity to promote positive behavioral changes—changes that increase resilience, well-being, and altruistic behavior.
