Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’.
Learning theory: models, product and process Learning theory: models, product and process. What is learning? Is it a change in behaviour or understanding? Is it a process? Here we survey some common models. Brain is not fully mature until 30s and 40s (PhysOrg.com) -- New research from the UK shows the brain continues to develop after childhood and puberty, and is not fully developed until people are well into their 30s and 40s. The findings contradict current theories that the brain matures much earlier. Professor Sarah-Jayne Blakemore, a neuroscientist with the Institute of Cognitive Neuroscience at University College London, said until around a decade ago many scientists had "pretty much assumed that the human brain stopped developing in early childhood," but recent research has found that many regions of the brain continue to develop for a long time afterwards. The prefrontal cortex is the region at the front of the brain just behind the forehead, and is an area of the brain that undergoes the longest period of development. Prof.
Decision-Making and Control in the Brain Damage to the brain's frontal lobe is known to impair one's ability to think and make choices. And now scientists say they've pinpointed the different parts of this brain region that preside over reasoning, self-control and decision-making. Researchers say the data could help doctors determine what specific cognitive obstacles their patients might face after a brain injury. Expanding the Science and Practice of Gratitude For too long, we’ve taken gratitude for granted. Yes, “thank you” is an essential, everyday part of family dinners, trips to the store, business deals, and political negotiations. That might be why so many people have dismissed gratitude as simple, obvious, and unworthy of serious attention. But that’s starting to change. Recently scientists have begun to chart a course of research aimed at understanding gratitude and the circumstances in which it flourishes or diminishes.
The Brain: A Body Fit for a Freaky-Big Brain Aiello and Wheeler noted that this dramatic increase in brain size would seem to have required a dramatic increase in metabolism—the same way that adding an air-conditioning system to a house would increase the electricity bill. Yet humans burn the same number of calories, scaled to size, as other primates. Somehow, Aiello and Wheeler argued, our ancestors found a way to balance their energy budget. As they expanded their brains, perhaps they slimmed down other organs. The scientists compared the sizes of organs in humans and other primates. Relatively speaking, our liver is about the same size as a baboon’s.
Constructivist Learning Theory Teaching with the Constructivist Learning Theory What is the best method of teaching to use? One of the first things a teacher must do when considering how to teach students is to acknowledge that each student does not learn in the same way. This means that if the teacher chooses just one style of teaching (direct instruction, collaborative learning, inquiry learning, etc.), the students will not be maximizing their learning potential. How Our Brains Feel Emotion With rendition switcher Question: What is happening in our brain when we feel an emotion? Antonio Damasio: Feeling of an emotion is a process that is distinct from having the emotion in the first place. UCSB scientists discover how the brain encodes memories at a cellular level (Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal Neuron, could eventually lead to the development of new drugs to aid memory. The team of scientists is the first to uncover a central process in encoding memories that occurs at the level of the synapse, where neurons connect with each other. "When we learn new things, when we store memories, there are a number of things that have to happen," said senior author Kenneth S. Kosik, co-director and Harriman Chair in Neuroscience Research, at UCSB's Neuroscience Research Institute.
MSNBC - How to Think About the Mind How to Think About the MindNeuroscience shows that the 'soul' is the activity of the brain Sept. 27 issue - Every evening our eyes tell us that the sun sets, while we know that, in fact, the Earth is turning us away from it. Astronomy taught us centuries ago that common sense is not a reliable guide to reality. Today it is neuroscience that is forcing us to readjust our intuitions. People naturally believe in the Ghost in the Machine: that we have bodies made of matter and spirits made of an ethereal something.

June Due to Khan Academy’s popularity, the idea of the flipped classroom has gained press and credibility within education circles. Briefly, the Flipped Classroom as described by Jonathan Martin is: Flip your instruction so that students watch and listen to your lectures… for homework, and then use your precious class-time for what previously, often, was done in homework: tackling difficult problems, working in groups, researching, collaborating, crafting and creating. Classrooms become laboratories or studios, and yet content delivery is preserved.
