The whole thing starts with cerebral cortex. It is divided into four major parts, or sometime people call it lobes.
1. Frontal
2. Parietal

Exeter University boffins have discovered ‘elixir of life’
For centuries humans have sought the ‘elixir of life’ – a mythical potion that supposedly would grant the drinker eternal life.
Now Exeter scientists believe they may have found the secret to a longer, healthier life.
New compounds developed and tested at the University of Exeter have brought the dream a step closer and paved the way for “anti-degeneration” drugs that could not only extend life, but also extend health and may help treat age-related diseases like cancer, dementia and diabetes.
Building a better brain
Like a team in a science fiction movie, the six-lab squad funded by a 2017 MEDx Biomedical research grant is striking in its combination of diverse skills and duties.
The project is led by Kafui Dzirasa, MD’09, Ph.D.’07, HS’10-’16, associate professor of psychiatry and behavioral sciences and assistant professor in neurobiology and neurosurgery; and Nenad Bursac, Ph.D., professor of biomedical engineering and associate professor in medicine. Their team includes: Marc Caron, Ph.D., James B. Duke Professor of Cell Biology, professor in neurobiology and medicine; Fan Wang, Ph.D., professor of neurobiology; Christopher Kontos, MD, HS’93-’97, professor of medicine and associate professor of pharmacology and cancer biology—all at Duke University School of Medicine—and Jennie Leach, Ph.D., associate professor of chemical, biochemical, and environmental engineering at the University of Maryland Baltimore County, along with a cadre of committed graduate students, postdocs, and technicians.
Dzirasa’s background in engineering informs his approach to the study of neuropsychiatric illness and disease. In the summer of 2016, he and members of his lab were discussing the challenge of precisely monitoring brain activity.
ETMC First Person — Todd Glass — deep brain stimulation
09−28−17 Todd Glass of Tyler shares his story of how the deep brain stimulation surgery, from the ETMC Neurological Institute, allowed him to gain back the ability to get back one of his life’s passions. See how Todd “rocked” the surgery suite at ETMC Tyler.
Boy Who Had a Chunk of Brain Removed Turned Out Healthy
The strange case of a young boy who had a large section of his brain removed shows just how good the human brain is at repairing itself — or at least making the most of a tough situation. Beyond being just a lump of tissue that named itself, the brain is also a kind of wonderful, wet computer that’s capable of rewiring itself in response to new experiences like taking drugs, forming new memories, and making friends. In extreme cases, like that of a 6-year-old boy who had about one-sixth of his brain removed, the brain can even adapt to getting cut apart.
Doctors documented the boy’s case in a paper published July 31 in the journal Cell Reports. They report that despite the boy having a significant portion of his brain removed, including the portion associated with visual processing, the boy has developed into a healthy 10-year-old. And while he still can’t see in the left side of his field of vision, his brain has reconfigured some of the lost connections so that he is able to recognize people’s faces. All in all, the doctors see it as a successful procedure, as well as evidence of the brain’s plasticity — its ability to adapt — when it comes to higher-order functions.
“He is essentially blind to information on the left side of the world. Anything to the left of his nose is not transmitted to his brain, because the occipital lobe in his right hemisphere is missing and cannot receive this information,” Marlene Behrmann, Ph.D., a professor of psychology at Carnegie Mellon University and the corresponding author on the paper, tells New Scientist.
A Case for Neural Augmentation
Hopefully in the future, when somebody tells you they will be making an appointment with a surgeon for an augment, they will come back smarter. The world will be a better place for it.

In a Future of Mind Uploading, Who Will Own the Data That is You?
The year is 2050 and researchers have developed an advanced method of replacing 99% of your brain’s functions for digital software/hardware. The process is slow to ensure individuals aren’t simply making copies of themselves. But in return, “digital immortality” has been achieved.
In a future of mind-uploaded “immortals,” will we achieve unlimited freedom or will we simply become slaves to a private entity which owns the data that makes up our own digital minds?
Study finds evidence that leopard geckos can make new brain cells
Published in Scientific Reports, this study is the first to provide evidence of new neuron formation—and the presence of stem cells—in the leopard gecko brain.
University of Guelph researchers have discovered the type of stem cell allowing geckos to create new brain cells, providing evidence that the lizards may also be able to regenerate parts of the brain after injury.
This finding could help in replacing human brain cells lost or damaged due to injury, aging or disease.
“The brain is a complex organ and there are so few good treatments for brain injury, so this is a very exciting area of research,” said Prof. Matthew Vickaryous in the Department of Biomedical Sciences at the Ontario Veterinary College (OVC).
