New Neural Chip Boosts Efficiency and Safety in Brain Stimulation
Researchers have developed an 8-channel neural stimulation chip that delivers exponential waveforms with 98% power efficiency, marking a breakthrough for brain-machine interfaces and neural modulation. The chip addresses key challenges in neural stimulation, including charge imbalance and the need for high power efficiency, ensuring safer and more effective treatments for conditions like Parkinsonβs disease and spinal injuries.
Magnetic Nanodiscs Offer Implant-Free Brain Stimulation
Scientists have developed magnetic nanodiscs that enable targeted brain stimulation without invasive implants or genetic modifications. The tiny discs, activated by an external magnetic field, deliver electrical pulses to neurons, showing potential in treating neurological conditions. Initial tests in mice demonstrated that these nanodiscs effectively stimulate brain regions linked to reward and motor control, with fewer foreign body responses compared to traditional implants.
