Researchers have gained new understanding of how the brain controls movement using both overt motor control and brain-machine interface (BMI) control. Their findings provide insight into the distinct neural processes involved in BMI control compared to natural movement. Key Facts: Rhesus monkeys were trained to control a cursor using either overt arm movements or a …
Electrical neural interfaces are unlocking new possibilities for studying, restoring, and augmenting brain functions. These devices provide direct communication pathways to connect the nervous system with the external world. Recent innovations in neural electrode design, electronics, wireless transmission, integration of electrical and optical modalities, and neural data processing are rapidly advancing the capabilities of electrical …
Brain-machine interfaces (BMIs) are emerging devices that connect the human brain to computers and machines, enabling an unprecedented two-way flow of information and control. BMIs offer extraordinary new capabilities but also present profound ethical dilemmas we must confront. Key Facts: BMIs acquire brain signals, analyze them via algorithms, and translate them into commands that control …
Invasive brain-computer interfaces (BCIs) allow for direct communication between the brain and external devices, offering immense potential for restoring lost functions and even enhancing brain capabilities. Recent advances are bringing this emerging technology closer to widespread clinical use. Invasive BCIs involve surgically implanted electrodes to record from or stimulate the brain. This allows for much …

Neuralink, a neurotechnology company founded by Elon Musk in 2016, is developing an innovative brain-machine interface (BMI) device that aims to enhance brain function and revolutionize neurosurgery. Early testing on animals shows promise, but human trials are still needed to determine safety and efficacy. If proven viable, Neuralink’s technology could transform treatment for neurological disorders. …
Researchers have developed a new artificial intelligence (AI) chip that mimics the human brain for more energy-efficient speech recognition. The analog AI chip uses phase-change memory devices to perform computations in parallel, dramatically reducing power consumption. In tests, the chip achieved up to 12.4 trillion operations per second per watt, 14 times more energy-efficient than …
Researchers have reconstructed a recognizable version of the Pink Floyd song “Another Brick in the Wall” directly from recorded brain activity. Using advanced machine learning techniques, the team was able to extract enough acoustic information from listeners’ brain signals to identify the song and recreate an intelligible version. Key highlights: Researchers recorded brain activity via …
Summary: Advances in brain-computer interface (BCI) technology could one day give voice to those who have lost the ability to speak. New research brings us one step closer to this goal by reconstructing identifiable words and sentences directly from brain activity. Major Findings: Researchers optimized deep learning models to reconstruct speech sounds from brain recordings …
