    Neurotechnology Lets a Paralyzed Person Use Their Brain to Fly a Virtual Drone
    Innovative technology linked with the brain is already helping restore the quality of life for many disabled individuals, such as one paralyzed patient who piloted a virtual drone by simply thinking. This breakthrough in neurotechnology, detailed in a recent study, demonstrates the exciting possibilities becoming available for those with motor impairments who want to enjoy recreational activities like playing video games.The study, published in Nature Medicine, was founded on paralyzed individuals' desire to engage in hobbies like sports or gaming, activities that may normally be difficult due to loss of movement in the body. By designing a brain-computer interface (BCI) to address this issue, researchers have made tremendous progress in showing how people who have developed physical impairments can enjoy games and socialize with friends in unprecedented ways.Implementing a Brain-Computer Interface The BCI created in the study was tested on a research participant with tetraplegia (or paralysis in all four limbs) caused by a spinal cord injury. The BCI separated the hand into three finger groups: the thumb and two pairs of fingers (the index and middle fingers and the ring and little fingers). To link this technology to the brain, electrodes are attached to the motor cortex and then exit the skin to be connected to a computer.It takes the signals created in the motor cortex that occur simply when the participant tries to move their fingers and uses an artificial neural network to interpret what the intentions are to control virtual fingers in the simulation, said Matthew Willsey, a University of Michigan professor of neurosurgery and first author of the study, in a statement.The signals are then sent to the computer and control the movement of a quadcopter through a virtual obstacle course. The participant involved in the study was tasked to complete the course, which involved maneuvering the drone through multiple rings as quickly and as accurately as possible.A Chance to Rise UpThe research was conducted as part of the BrainGate2 clinical trials, which intend to determine how people with tetraplegia can use a neural interface to control assistive devices and navigate communication software. The trials represent a critical opportunity for those with neurological injuries or diseases that inhibit the ability to use both hands: this includes cervical spinal cord injury, brainstem stroke, muscular dystrophy, and ALS among other conditions.The paralyzed participant has worked with researchers as far back as 2016, and expressed a particular interest in flying the virtual drone. A major theme of the study's results was the sense of enablement that the BCI gave the participant. He voiced his enthusiasm to complete the quadcopter sessions, as they made him feel like he could figuratively rise up out of his bed or chair. New Possibilities for Disabled PatientsPrevious BCIs have tested movement through point-and-click cursors and robotic arms that can grasp objects, but this newly developed BCI targets more complex finger control that could allow a paralyzed individual to perform activities like playing a musical instrument or using a digital video game controller.The possibilities for BCIs to give disabled patients access to a wider range of activities are growing as neurotechnology evolves. A noteworthy outcome of this development is that these people will feel more connected with others, fostering a healthy level of socialization and helping them overcome barriers related to their disability that sometimes go unnoticed.People tend to focus on restoration of the sorts of functions that are basic necessities eating, dressing, mobility and those are all important, said Jaimie Henderson, a professor of neurosurgery at Stanford University and a co-author of the study. But oftentimes, other equally important aspects of life get short shrift, like recreation or connection with peers. People want to play games and interact with their friends.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

    Contagious Urinations Cause Chimps to Go in Groups
    A new paper published in Current Biology suggests a novel twist on an old saying: Instead of "monkey see, monkey do," the paper proposes "chimp see, chimp pee." Well, not in so many words. But the study, which involved 20 captive chimpanzees at the Kumamoto Sanctuary at Kyoto University, does suggest that when one chimp urinates, others urinate too. In humans, urinating together can be seen as a social phenomenon, said Ena Onishi, a study author and a doctoral student at Kyoto University, in a press release. This behavior, which is called tsureshon in Japanese, is represented in art across centuries and cultures and continues to appear in modern social contexts. Our research suggests that this phenomenon may have deep evolutionary roots.Contagious PeeingWhen researchers at the Kumamoto Sanctuary saw something strange in the behavior of their captive chimpanzees, they set out to study it. Instead of urinating alone, the chimps appeared to urinate together, at around the same time, with one chimp initiating the behavior and other chimps continuing it. Calling the behavior contagious urination, the researchers wanted to see whether it was at all similar to contagious yawning, whereby a chimpanzee or a human yawns, causing onlooking chimps or humans to do the same.Since there were no prior studies on contagious urination in any species, we drew parallels to contagious yawning, another semi-voluntary physiological behavior, said Onishi in the release.Observing the Kumamoto chimpanzees for over 600 hours, then documenting the almost 1,330 urinations that occurred during that time, the researchers determined whether the chimpanzees urinations were synchronized. They also determined whether the chimps urinations were influenced by their physical proximity and their social closeness.We found that chimpanzees, our closest relatives, tend to urinate in response to the urination of nearby individuals, Onishi said in the release.According to the researchers, the results reveal important insights into the social groupings of chimps, helping us understand how they get and stay together, through cohesion, connection, and, apparently, urination. Read More: Are Chimpanzees Capable of Empathy?Synchronized Peeing PatternsAfter analyzing their observations, the researchers concluded that the chimps urinations were synchronized, occurring at around the same time much more frequently than if they were randomized. But their analysis also identified other trends in the chimpanzees urination, too. For instance, the chimps urinations were more synchronized when the chimpanzees were closer together in terms of their physical proximity, though not in terms of their social closeness.We initially expected that any social influences might resemble those seen in yawning such as stronger contagion between socially close pairs, Onishi said in the release. However, our results showed no evidence of effects related to social closeness.Instead, the researchers revealed a strong influence of social hierarchy, with higher-status chimps urinating alone and lower-status chimps urinating in response to the higher-status individuals.We observed a clear influence of social rank, with lower-ranking individuals being more likely to follow the urination of others, said Onishi in the release. We were surprised to discover that the contagion pattern was influenced by social rank.Though the purpose and mechanisms of contagious urination remain a mystery, the researchers say that their results are unprecedented, representing the first formal study of contagious urination in any species.This was an unexpected and fascinating result, as it opens up multiple possibilities for interpretation, said Shinya Yamamoto, another study author and an associate professor at Kyoto University, in the release. These findings raise intriguing questions about the social functions of this behavior.

    Patient with paralysis uses mind to pilot virtual quadcopter
    A screenshot of the game display shows the quadcopter following a green path around the rings. The inset shows a hand avatar. The neural implant records from nearby neurons and algorithms determine the intended movements for the hand avatar. The finger positions are then used to control the virtual quadcopter. Credit: University of Michigan / Nature MedicineShareMultiple brain-computer interface (BCI) projects are currently underway, but BrainGate is one of the first aimed at motor restoration in users affected by neurodegenerative disorders and spinal cord injuries. Researchers have spent years working through the devices clinical trial phases, but their most recent breakthrough isnt focused on physical accomplishments. Instead, the latest achievements could pave the way for people with disabilities to more easily utilize complex computer software, communicate with loved ones, work remotely, and even make music.According to a study published by BrainGate engineers on January 20 in the journal Nature Medicine, a volunteer with quadriplegia can now maintain unprecedented control over a virtual object using their surgically implanted BrainGate BCI device. To demonstrate the ability, the patient guided a virtual rotocopter through hoops in a digital obstacle course by simply thinking about moving the fingers on one of their hands.This is a greater degree of functionality than anything previously based on finger movements, Matthew Willsey, study first author and a University of Michigan assistant professor of neurosurgery and biomedical engineering, said in an accompanying announcement.Noninvasive BCI technology already exists to help users with physical restrictions operate computer software and video games, often relying on electroencephalography (EEG) signals. Willsey and his colleagues, however, note that these methods require analyzing larger regions of the brain beyond the motor cortex. Because of this, the engineers believe placing microthin electrode wiring closer to the actual neurons allows for the restoration of more precise motor control.[BrainGate2] takes the signals created in the motor cortex that occur simply when the participant tries to move their fingers and uses an artificial neural network to interpret what the intentions are to control virtual fingers in the simulation, said Willsey.The updated BrainGate BCI system works by analyzing the users hand in three partsthe thumb, then the index and middle fingers, followed by the ring and pinky fingers. Each section is also defined by its horizontal and vertical movements. To guide a virtual quadcopter through its digital obstacle course, the BCI user only needs to think about moving those hand groupings as needed to fly the vehicle through the floating hoops.The volunteer, who cannot move their limbs after sustaining a spinal cord injury many years ago, has worked with Willseys team since 2016. But unlike some of the previous trials, this one was specifically tailored to their interests. Get the Popular Science newsletter Breakthroughs, discoveries, and DIY tips sent every weekday.

While also fulfilling the participants desire for flight, the platform also showcased the control of multiple fingers.According to the teams results, the BrainGate array wired directly to motor neurons offered a sixfold improvement on the users quadcopter piloting when compared to an EEG system. This digital precision may soon extend much further than copter steeringit could allow for greater connectivity between the BCI user and their friends and loved ones.People tend to focus on restoration of the sorts of functions that are basic necessitieseating, dressing, mobilityand those are all important, explained Jaimie Henderson, a neurosurgery professor at Stanford and study co-author. But oftentimes, other equally important aspects of life get short shrift, like recreation or connection with peers. People want to play games and interact with their friends.Henderson said there are also practical implications to the BCI improvements showcased in the quadcopter trialsthe ability to control multiple virtual fingers allows for multifactor control schemes for all kinds of things, including using CAD software and composing music.

However, for the best results, follow Seroc Ifkres path exactly.How to make a great Necromancer buildNecromancers are Diablo 4s main summoning class although Druids, ironically, had better summons during the games launch window. But aside from their army of minions, Necromancers also act as a darker caster, sharing a lot of playstyle DNA with the Sorcerer.Like all classes, most Necromancer builds boil down to a few Key Passives:BoneBlood/HealthShadowMinionBone skills like Bone Spear hit extremely hard for Necromancers, and are great for chunking down enemies. The Ossified Essence Key Passive modifies that damage even further for players that successfully pool their Essence. Blood builds utilize Blood skills to both keep the Necromancer healthy while dealing big damage. These builds typically end with the Rathmas Vigor Key Passive.Shadow builds use Shadow skills to poison enemies with dark essence. Interestingly, the Shadowblight Key Passive not only benefits the Necromancer, but also their minions, making it a more diverse build path. Minion builds are Necromancers main bread and butter, but are entirely dependent on how good minions are in the current meta. When theyre useful, these builds end with the Kalans Edict Key Passive.Like all classes, Necromancer builds have other identities to them like Thorns but most will converge on one of the four identities highlighted above. What really determines build viability on Necromancer is how you use your minions and the Book of the Dead. If you want to make your own build, decide early on if you want to sacrifice your minions or use them in battle. This will not only determine which skills youll want to use, but which of the four Key Passives you want to angle toward.Looking for other Diablo 4 builds? We have explainers on the Spiritborn, Sorcerer, Rogue, Druid, and Barbarian classes.
