The first endovascular neural interface, the Stentrode™ is a minimally invasive implantable brain device that can interpret signals from the brain for patients with paralysis. Implanted via the jugular vein, the #Stentrode is placed inside the #brain in the command-control center, known as the motor cortex, but without the need for open brain surgery. The signals are captured and sent to a wireless unit implanted in the chest, which sends them to an external receiver. We are building a software suite that enables the patient to learn how to control a computer operating system and set of applications that interact with assistive technologies. This #technology has the potential to enable patients with paralysis to take back digital control of their world, without having to move a muscle.

Synchron is currently preparing for pilot clinical trials of the Stentrode™ to evaluate the safety and efficacy of this breakthrough technology.

Dog and cat linguists rejoice we can talk to them and understand them with lots of apps and other devices in this article 😀 😊 😄 😉.

All dog owners have wished there was such a thing as a translator for their dog. The movie Up brings this concept to life with a collar that translates everything the dog says. But does a dog translator exist in real life? We might not have flying cars yet in the 21st century, but dog translators do exist.

There’s no longer a need to guess everything your dog is saying when you can buy dog translator collars, buttons, neural devices, and apps to help you translate what your dog wants to say.

The mesh has already proved successful on fruit fly larvae in Minnesota, and with two species of mushroom coral in Hawaii and Australia. In Florida, Hagedorn and colleagues were trying it on Diploria labyrinthiformis, a kind of brain coral whose larvae are more than 100 times bigger than those of mushroom coral. In the first few attempts, rewarmed larvae were falling apart. Each larval size, Hagedorn was learning, needs its own version of the treatment. “We’re struggling a little bit to get this to work,” she says.

WHILE SCIENTISTS such as Bischof and Hagedorn wrestle with vitrification, others are seeking an easier route by avoiding ultralow temperatures that require large infusions of cryoprotectant and make rewarming so challenging.

At Harvard University and MGH, scientists are taking cues from nature to push tissues below freezing while holding back the ice. The wood frog (Rana sylvatica) is a champion of this realm. Found in much of North America, including the frigid Canadian Arctic, it can spring to life after spending months with as much as two-thirds of its body frozen at temperatures as low as −16°C.

Ever wonder where in your brain that interesting character called “I” lives? Stanford Medicine physician-scientist Josef Parvizi, MD, PhD, has news of its whereabouts.

If skulls were transparent, you still wouldn’t see much going on in someone else’s brain. But Parvizi has ways of peeking into people’s heads and finding out what makes us tick. His experiments have pinpointed specific brain regions crucial to capabilities ranging from perceiving faces to recognizing numerals.

In January 6 2023, the U.S. Food & Drug Administration approved Leqembi (lecanemab-irmb) via the Accelerated Approval pathway for the treatment of Alzheimer’s disease. Leqembi is the second of a new category of medications approved for Alzheimer’s disease that target the fundamental pathophysiology of the disease. These medications represent an important advancement in the ongoing fight to effectively treat Alzheimer’s disease.

Recently it has been granted full approval. Leqembi, developed jointly by Japan’s Eisai and Biogen of the United States, was shown in a clinical trial to modestly reduce cognitive decline among patients in the early stages of the disease.

But the study also raised concerns about side effects including brain bleeds and swelling.

Full approval story.

The animal world is full of different types of intelligence, from the simple bodily coordination of jellyfish to the navigation abilities of bees, the complex songs of birds, and the imaginative symbolic thought of humans.

In an article published this week in Proceedings of the Royal Society B, we argue the evolution of all these kinds of animal intelligence has been shaped by just five major changes in the computational capacity of brains.

Each change was a major transitional point in the history of life that changed what types of intelligence could evolve.

Restoring And Extending The Capabilities Of The Human Brain — Dr. Behnaam Aazhang, Ph.D. — Director, Rice Neuroengineering Initiative, Rice University

Dr. Behnaam Aazhang, Ph.D. (https://aaz.rice.edu/) is the J.S. Abercrombie Professor, Electrical and Computer Engineering, and Director, Rice Neuroengineering Initiative (NEI — https://neuroengineering.rice.edu/), Rice University, where he has broad research interests including signal and data processing, information theory, dynamical systems, and their applications to neuro-engineering, with focus areas in (i) understanding neuronal circuits connectivity and the impact of learning on connectivity, (ii) developing minimally invasive and non-invasive real-time closed-loop stimulation of neuronal systems to mitigate disorders such as epilepsy, Parkinson, depression, obesity, and mild traumatic brain injury, (iii) developing a patient-specific multisite wireless monitoring and pacing system with temporal and spatial precision to restore the healthy function of a diseased heart, and (iv) developing algorithms to detect, predict, and prevent security breaches in cloud computing and storage systems.

Dr. Aazhang received his B.S. (with highest honors), M.S., and Ph.D. degrees in Electrical and Computer Engineering from University of Illinois at Urbana-Champaign in 1981, 1983, and 1986, respectively. From 1981 to 1985, he was a Research Assistant in the Coordinated Science Laboratory, University of Illinois. In August 1985, he joined the faculty of Rice University. From 2006 till 2014, he held an Academy of Finland Distinguished Visiting Professorship appointment (FiDiPro) at the University of Oulu, Oulu, Finland.
