prosthetic device implanted in a region of the brain where intentions are made, giving him the ability to perform a fluid handshaking gesture,
Neural prosthetic devices implanted in the brain movement center, the motor cortex, can allow patients with paralysis to control the movement of a robotic limb.
However, current neuroprosthetics produce motion that is delayed and jerkyot the smooth and seemingly automatic gestures associated with natural movement.
Now, by implanting neuroprosthetics in a part of the brain that controls not the movement directly but rather our intent to move,
Andersen and his colleagues wanted to improve the versatility of movement that a neuroprosthetic can offer to patients by recording signals from a different brain region other than the motor cortex, i e.,
, the posterior parietal cortex (PPC), a high-level cognitive area. In earlier animal studies, the Andersen lab found that it is here
These intentions are transmitted then to the motor cortex, through the spinal cord, and on to the arms and legs where the movement is executed. he PPC is earlier in the pathway,

#Researchers Find Missing Link Between the Brain and Immune system In a stunning discovery that overturns decades of textbook teaching,
researchers at the University of Virginia School of medicine have determined that the brain is connected directly to the immune system by vessels previously thought not to exist.
ow do we study the immune response of the brain? hy do multiple sclerosis patients have the immune attacks?
Because the brain is like every other tissue connected to the peripheral immune system through meningeal lymphatic vessels,
said Jonathan Kipnis, Phd, professor in the UVA Department of Neuroscience and director of UVA Center for Brain Immunology and Glia (BIG).
The vessels were detected after Louveau developed a method to mount a mouse meninges the membranes covering the brain on a single slide
'As to how the brain lymphatic vessels managed to escape notice all this time, Kipnis described them as ery well hiddenand noted that they follow a major blood vessel down into the sinuses, an area difficult to image. t so close to the blood vessel,
Alzheimer, Autism, MS and Beyond The unexpected presence of the lymphatic vessels raises a tremendous number of questions that now need answers, both about the workings of the brain and the diseases that plague it.

#Deficiency of Specific Protein in Brain Blood vessels Increases Risk for Alzheimer Disease New study finds that PICALM protein regulates removal of toxic plaques from brain.
Sientists at the Keck School of medicine of USC have discovered that a protein known as PICALM regulates removal of toxic plaques from the brain,
characterized by the loss of memory and other mental abilities linked to an accumulation of amyloid-beta and other toxic compounds in the brain.
disable amyloid-beta from being cleared out of the brain across a region known as the blood-brain barrier. here have been many new genes discovered to be associated with Alzheimer disease,
and its variants associated with increased risk for the disease inactivate amyloid-beta clearance from the brain,
Autopsies from Alzheimer patients and recent research in experimental models have shown the importance of brain blood vessels in the disease initiation and progression.
Zlokovic and his research team have studied the cellular and molecular mechanisms of brain blood vessels that maintain normal cognition with hopes of developing new treatments for Alzheimer and other neurodegenerative diseases.
the group found that low levels of PICALM in brain endothelial cells lead to amyloid-beta accumulation in the brain.
and Age Related Neurodegeneration The process that allows our brains to learn and generate new memories also leads to degeneration as we age, according to a new study by researchers at MIT.
our brain cells break their DNA, creating damage that the neurons must immediately repair, according to Li-Huei Tsai, the Picower Professor of Neuroscience and director of the Picower Institute for Learning and Memory at MIT.
our brains create DNA breaks as we learn new things, but our cells are absolutely on top of this
neurons in the hippocampal region of the brain contain a large number of DNA lesions, known as double strand breaks.
This research has been collaboration between many distinct research groups combining cell biology to neuroscience. o sole research group could have achieved such a comprehensive view of the dendritic spine initiation mechanism and show its importance for the brain function

#Imaging Technique Provides Color Coded Map Showing Cancerous Brain areas New imaging technique could make brain tumor removal safer and more effective,
Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible
while keeping crucial brain tissue intact and visually distinguishing the two is often impossible. Now Johns Hopkins researchers report they have developed an imaging technology that could provide surgeons with a color-coded map of a patient brain showing
which areas are and are not cancer. A summary of the research appears June 17 in Science Translational Medicine. s a neurosurgeon,
thought OCT might provide a solution to the problem of separating brain cancers from other tissue during surgery.
Eventually, the researchers figured out that a second special property of brain cancer cells that they lack the so-called myelin sheaths that coat healthy brain cells had a greater effect on the OCT readings than did density.
Once they had found the characteristic OCT ignatureof brain cancer, the team devised a computer algorithm to process OCT data and,
the team has tested the system on fresh human brain tissue removed during surgeries and in surgeries to remove brain tumors from mice.
In a recent study, scientists from the Max Planck Institute for Human Cognitive and Brain sciences in Leipzig, the University of Amsterdam and INSERM Caen have pinpointed the location of musical memory for the first time
and shown that this area of the brain remains largely intact despite progressive degeneration of the brain in Alzheimer patients.
the researchers first located the seat of long-term musical memory in the brain with the help of functional ultra-high-field magnetic resonance imaging.
The scientists were able to conclude from the various active brain areas which of the three categories (long-known, recently heard,
They identified a region in the supplementary motor cerebral cortex that is responsible for long-term musical memory an area that is involved in movement. ur study shows that the temporal lobes are not essential for musical memory,
loss of neurons, reduced metabolism and deposition of amyloid protein in the affected brain areas. They found that the brain area that had been identified as the seat of long-term musical memory does in fact lose fewer neurons than the rest of the brain.
Also, metabolism in this area does not decline as much. The extent of amyloid deposits is similar to that in other areas of the brain
but does not lead to the deficits otherwise associated with advanced stages of the disease.
The brain areas responsible for long-term musical memory are affected therefore often least by neuron loss and typical metabolic disorders in Alzheimer patients.
This suggests that this area of the brain also provides specific compensatory functions as the disease progresses,

#Researchers Discover New Epigenetic Mecahnism in Brain cells For decades, researchers in the genetics field have theorized that the protein spools around
histones, remain constant in the brain, never changing after development in the womb. Now, researchers from the Icahn School of medicine at Mount sinai have discovered that histones are replaced steadily in brain cells throughout life a process
which helps to switch genes on and off. This histone replacement, known as turnover, enables our genetic machinery to adapt to our environment by prompting gene expression,
and carry signals in the brain. This new concept described in a study led by researchers in the Department of Pharmacology and Systems Therapeutics at the Icahn School of medicine at Mount sinai,
The research team found that histone turnover regulates how genes in the brain are turned on and off in response to various stimuli,
the study examined a specific type of histone called H3. 3 in human and rodent brains.

#Brain implant allows paralysed man to sip a beer at his own pace A brain implant that can decode what someone wants to do has allowed a man paralysed from the neck down to control a robotic arm with unprecedented fluidity
People with similar injuries have controlled previously prosthetic limbs using implants placed in their motor cortex an area of the brain responsible for the mechanics of movement.
Richard Andersen at the California Institute of technology in Pasadena and his colleagues hoped they could achieve a more fluid movement by placing an implant in the posterior parietal cortex a part of the brain involved in planning motor movements."
"We thought this would allow us to decode brain activity associated with the overall goal of a movement for example,
Neuron control Andersen's team placed two implants measuring 4 millimetres squared into Sorto's posterior parietal cortex.
"The posterior parietal cortex is a fascinating area as it doesn't control the muscles so much as the plans you make to do something."
One unexplored possibility is that the posterior parietal cortex might also encode other kinds of intentions.
could we identify the brain activity that corresponds with the thought of wanting to watch a film,
because the messages from the nerves cannot reach the brain. It might be possible to stimulate the brain directly instead.

#Leaky Blood vessels In The Brain May Lead To Alzheimer's Researchers appear to have found a new risk factor for Alzheimer's disease:
"This is exactly the area of the brain that is involved with learning and memory,"says Berislav Zlokovic, the study's senior author and director of the Zilkha Neurogenetic Institute at the University of Southern California.
"We were looking at brains from autopsies and it (became) quite apparent that there is a breakdown of the blood-brain barrier,
and toxins that circulate in the bloodstream from mixing with the fluid that surrounds brain cells.
toxins leak into the fluid that surrounds brain cells and eventually damage or kill the cells.
So Zlokovic and his team used a special type of MRI to study the living brains of more than 60 people.
The researchers paid special attention to the hippocampus because it is one of the first brain areas affected by Alzheimer's.
