Summaries In the article by New York Times “Brains as Clear as Jell-O for scientist to Explore” is an excellent title. Scientist at Stanford University has made the entire transparent model of a mouse brain and part of a human brain so the networks of neurons can be seen in three-dimensional. The new process is called Clarity. The model can be used repeatedly. The goal of making these models is to be able to create and prevent cures for diseases such as schizophrenia, autism, and posttraumatic stress. IT corresponds with Obamas Brain initiative. The possibilities of using old brains saved to see the evolution of the human brain through the years. Although the brain of a mouse is much smaller and less complex of the human, it is a step to modeling the entire human brain. The technique optogentics is used to control the on and off switch of the brain during testing. Dr. Jeff Lichtman at Harvard developed the process of breading mice that are genetically altered to make their brain neurons fluoresce. The key of making a brain model is to make the tissue transparent. The new technique to make the brain transparent is called hydrogel. Although making the model is just part of the challenge having the correct combination of conditions of temperature, electricity and solution is viable to success. As mentioned in the article scientist have burned and melted brains due to those conditions. The article “Nanotools for Neuroscience and Brain Activity Mapping” is the experiment of A. Paul Alivisatos. Nanoscience and nanotechnology have come together to attempt to map the brain and observe its functions. The purpose of the experiment was to measure the activity of the large set of neurons in the circuits, analyze, and model the circuits of the brain. Lastly, to test the models by altering conditions and see how neurons behave in the circuit. The article “Why dissonant music
