Researchers examine how stroke patients develop post-stroke sensory reweighting (PSR) to improve walking and balance. PSR is a critical factor in determining patient outcomes, with those who develop it experiencing better balance and reduced risk of falls.
Researchers engineered miniature linear and split-belt treadmills to study insect locomotion, gaining insights into proprioception's role in natural activities like walking. The study showed that flies can modify their steps to continue walking straight despite rotational perturbations.
Research by York University finds astronauts can safely assess distances in microgravity environments, which may provide clues to understanding balance systems on Earth. The study suggests that humans are able to compensate for the lack of gravity using vision, enabling precise movements and evasive maneuvers.
Researchers discovered that brains prioritize integrating muscle spindle input to understand body movement and position. Task-driven neural network models were found to be most effective in predicting limb position and velocity.
A new study reveals that lampreys use body-sensing feedback to regain swimming abilities after spinal injury, challenging the conventional view of neural regeneration. Mathematical models suggest that this technique could be applied to humans with spinal injuries or diseases affecting movement.
Scientists have identified genes that enable proprioception, a crucial sense for coordinated movement and balance. The discovery could lead to better understanding of neurological disorders such as spinal cord injuries, scoliosis, and hip dysplasia, ultimately enabling the development of novel therapies.
Researchers studied the body ownership illusion using integrated information theory, discovering a relationship between local and global brain-body processes. This work may help explain altered states of consciousness, such as the blurring of self and non-self, leading to feelings of uneasiness.
A team from the University of California San Diego has developed a new system of algorithms that enables four-legged robots to walk and run on challenging terrain while avoiding obstacles. The system combines vision with proprioception, allowing the robot to move efficiently and smoothly in various environments.
Scientists at the University of Groningen developed wearable, stitchable, and sensitive sensors from flexible polymers and carbon fibre. These sensors can measure body position, movement, and touch, offering new possibilities for health monitoring and athlete performance tracking.
Researchers find that individuals without a sense of touch can use visual cues to navigate and orient themselves, while those who lose the sense as adults may develop compensatory skills using conscious thought. The study suggests that the brain can adapt to sensory information loss and find alternative ways to process visual data.
A study involving two participants with sensory impairments reveals that physical embodiment can occur without the sense of touch. Kim and Ian, who cannot feel touch, use visual information to develop a sense of their bodies. Their unconscious body representations differ from those of control subjects.
A study by Kazumichi Matsumiya found two distinct neural substrates for body localization and ownership, indicating a need to revise existing models. The findings suggest that spatial localization and body ownership are processed differently in the brain.
Researchers have developed a prosthetic that restores the sense of where your hand is, allowing amputees to feel tactile sensations and proprioception in real time. The new device uses intraneural stimulation to deliver simultaneous position and tactile feedback, resulting in improved function and prosthesis embodiment.
A team of researchers identified the gene 'TRP-1' and 'TRP-2', which enable balanced and smooth body movements in C. elegans, a simple nervous system model. The study suggests that TRP-1 and TRP-2 are proprioception sense receptors controlling neural activity and muscle movement.
Researchers at the University of Delaware used a new mirror box illusion to study how the brain processes multiple sensory inputs. The study found that the brain uses biomechanical constraints from the body schema to resolve conflicts between senses, with vision typically ruling but also considering additional information.
A team led by TSRI researchers identifies Piezo2 as the long-sought protein sensor for proprioception, allowing scientists to better understand this essential sense. The discovery may also lead to a deeper understanding of human diseases related to proprioception.
A new study improves brain-machine interface control by adding a robotic arm providing kinesthetic information, enhancing the design of 'wearable robots' for paralyzed patients. This approach may help spinal cord injury patients operate computers and robots using only their thoughts.
