Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Describe the symptoms, potential causes, and treatment of several examples of nervous system disorders
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Light-responsive proteins have revolutionized our understanding of the brain. By introducing the genes encoding these proteins into neurons and then exciting the cells using lasers – a technique known as optogenetics – individual cells can be rapidly turned on or off, enabling exquisitely sensitive investigations of brain function. But a fundamental limitation of the method is that light doesn’t travel very far through brain tissue, which has hampered the study of more buried – and often vital – structures. Now, researchers at the RIKEN Center for Brain Science have developed a way to extend the reach of optogenetics by nearly an order of magnitude, providing new possibilities for deep-brain stimulation. The team accomplished this using a special type of nanoparticle known as an upconversion nanoparticle, so named for its ability to transform – or “upconvert” – near-infrared light into visible output..."
