People with Down syndrome usually have smaller brain volumes than control groups including significantly smaller cerebellums a portion of the brain involved in motor control.
when it comes to brain development so fiddling with it could have unintended consequences. It's possible enhancing the biochemical events that lead to growth in the brain would cause issues elsewhere in the body like potentially raising the risk of cancer.

Jonathan Viventi Builds Devices That Decode Thoughts Existing brain implants require individual electrodes to be wired to an external device for data processing.
Viventi s arrays contain transistors that enable the signals to be processed locally yet they're as thin and flexible as a sheet of cellophane conforming to the contours of the brain.
We can actually sample with extremely high resolution across a virtually unlimited area of the brain Viventi says.

The signals from the sensors are relayed then to an external unit where they are processed before being passed back to the nerves in a format that allows the brain to understand how much pressure is being exerted on the sensors much like how information is passed from a real hand to the brain.
and it was found that the brain automatically assimilated data from multiple sensors in the palm of the hand.
For this to have now been developed into a method that supports the ability of the brain to assimilate impulses from 2 different areas to allow the subject to feel the neurologically complex action of palm closure is something exceptional.

and as the user looks at them their brain synchronizes at the same rate. This brain pattern reading system developed by Rosanne Zerafa relies on a system involving Steady State Visually Evoked potentials (SSVEPS.
Electrical signals sent by the brain are picked then up by a series of electrodes placed at specific locations on the userâ#scalp.
This process known as electroencephalography (EEG) records the brain responses and converts the brain activity into a series of computer commands.
As the user looks at the boxes on the screen the computer program is able to figure out the commands allowing the music player to be controlled without the need of any physical movement.
and link directly from the brain to certain areas of the body bypassing the spine altogether.
This particular brain-computer interface exploits one of these; the occulomotor nerve which is responsible for the eyeâ#movements.

#Prosthetic hand'tells'the brain what it is touching Research on prosthetic hands has come a long way,
implanted an array of small electrodes into the region of the brain that controls movement in a woman who is paralyzed.
The electrodes communicated electrical activity from the brain's motor cortex via wires, to a prosthetic arm that the woman was able to move through a wide range of motions.
The researchers showed that this feedback system allowed the hand to communicate directly with the brain.
Although the current demonstration is the first of a prosthetic hand directly communicating with the brain,
other researchers have demonstrated that they can send messages from sensors in the prosthetic hand to electrodes implanted in nerves in the arm that then communicate with the brain."(
The idea of implanting an electrode array into the brain to either control or receive signals from a prosthetic limb is big step forward,

#New Memristors Could Usher in Bionic Brains Last month we saw researchers in the US push the envelope of nonvolatile memory devices based on resistance switching to the point where they are now capable of mimicking the neurons in the human brain.
The researchers claim that the memristive devices they have developed mimic the brain ability to simultaneously process
and process information in the very same way that the brain does said Dr Hussein Nili,
but instead offers something akin to how the brain retains and recalls information. The researchers believe that these nanoscale memory devices promise a future of artificial intelligence network that could enable a so-called bionic brain.
Nili suggests that one of the potential applications for these nano-memory devices could be in replicating the human brain outside of the human body.
Nili added: f you could replicate a brain outside the body, it would minimize ethical issues involved in treating

#Sleep Position May Impact Brain Ability to Clear Waste How you sleep on your side, on your back,
but body position might actually affect how efficiently the brain clears waste, according to new research out of Stony Brook University.
the glymphatic pathway is where cerebrospinal fluid (CSF) filters through the brain and exchanges with interstitial fluid (ISF) to clear waste chemicals,
such as amyloid B and tau proteins, from the brain. The buildup of these proteins and other waste chemicals is suspected in the development of neurological diseases including Alzheimer.
which is a brain-wide pathway that runs along (i e. on the outside) of all vessels in the brain and connects to the space surrounding brain cells (referred to as the ISF space),
has been studied in detail in animal models. The outer part of the network ubeis bordered by a certain type of brain cells, known as stroglialcells,
The astoglial cells endfeet cover>97 percent of the surface of all brain vessels. ne can think of this
Researchers Discover Missing Link Between Brain and Immune Systemshe explained how the system lushesout waste:
Cerebrospinal fluid (CSF) circulates into the glymphatic pathway from the surface of the brain along the arteries
which dives directly from the surface into the deeper part of the brain; and ultimately enters the space around the brain cells;
and sweeps through it and thereby mixes with the interstitial fluid of the brain which contains waste products.
and therefor the assessment of the clearance of damaging brain proteins that may contribute to
or cause brain diseases. o why is the glymphatic system more effective when sleeping in the lateral position?
In other words it appears that ess CSF in this position actually enters the brain glymphatic pathway and therefore overall waste clearance is diminished. his could have implications for prevention of certain neurodegenerative diseases. e speculate that
(if it worked efficiently) that these products are allowed not to accumulate excessively in the brain. nce these proteins build up they can form aggregated plaques,
which can be very difficult for the brain to get rid of. hus, any lifelong habits that can promote optimal waste removal via the glymphatic pathway might help prevent
