The cerebellum, traditionally linked to motor functions, also plays a vital role in social and cognitive abilities, according to new research. Abnormalities in this brain region not only impair movement but are linked to emotional and behavioral issues, particularly in autism.

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 Parkinson’s disease and spinal injuries.

A new study demonstrates that home-based transcranial direct current stimulation (tDCS) is a safe and effective method for treating depression. Participants in the study who used tDCS at home showed significant improvements in depressive symptoms compared to those in a control group.

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.
