Figuring out what’s going on in the brain is generally considered to be somewhere between extremely difficult and impossible. One major challenge is that the best ways to do so are room-sized machines relegated to hospitals — but brain.space is hoping that its portable, powerful and, most importantly, user-friendly EEG helmet could power new applications and treatments at home and, as a sort of cork pop for its debut, in space.

Electroencephalography, or EEG, is an established method for monitoring certain signals the brain produces. An EEG can indicate which areas of the cortex are active, whether the user is concentrating, agitated, and so on. It’s not nearly as precise as an MRI, but all you need for an EEG is a set of electrical contacts on the scalp, while an MRI machine is huge, loud and incredibly expensive.

There’s been precious little advancement in EEG tech, though, and it’s often done more or less the same way it was done decades ago. Recently, that’s begun to change with devices like Cognixion’s, which uses re-engineered EEG to interpret specific signals with the goal of allowing people with motor impairments to communicate.

Nanotechnology was once the stuff of science fiction, but today the concept of creating devices and machines that are several thousand times smaller than the width of a human hair is a well-established fact. The rise of nanotechnology has already transformed industries ranging from consumer electronics to textile manufacturing and cosmetics by unlocking new materials and processes at the nanoscale. The device you’re reading this on, for example, is only possible because of techniques adopted in the semiconductor industry that enable us to pattern silicon and metals to create the microscopic circuits and switches that are at the heart of modern computers.

One of the most promising applications of our newfound ability to manipulate individual atoms and molecules is in healthcare, where the ability of doctors to treat disease has been hamstrung by relatively blunt “macro” solutions. The human body is a remarkably complex system where, fundamentally, nanoscale processes occurring inside cells are what determine whether we are sick or healthy. If we’re ever going to cure diseases like diabetes, cancer or Alzheimer’s, we need technologies that work at their scale. Although medical nanotechnologies are relatively new, they’re already impacting the way we diagnose, treat and prevent a broad range of diseases.

According to recent research, dementia risk in older persons may be increased by vision issues. According to a recent systematic review and meta-analysis of 16 studies comprising 76,373 individuals, older adults with untreated eyesight problems may have a higher chance of developing dementia. Th.

Heating up Twitter feeds this week was a new commentary about a rarely discussed perspective on autism, talk about the use of optogenetics tools to manipulate ‘presynapses,’ a possible explanation for decision-making differences between the sexes, and a striking illustration of the human brain.

Summary: Researchers reveal how neurons set up and sustain the vital infrastructure that allows for seamless neurotransmission.

The nervous system works because neurons communicate across connections called synapses. They “talk” when calcium ions flow through channels into “active zones” that are loaded with vesicles carrying molecular messages.

Neuroscientist and physician Matthew Schrag found suspect images in dozens of papers involving Alzheimer’s disease, including Western blots (projected in green) measuring a protein linked to cognitive decline in rats.
