40-Hz Light and Sound Therapy Aims to Slow Alzheimer’s Progress

Researchers are testing non-invasive 40 Hz flickering lights paired with precise audio to modulate memory-related brain activity in Alzheimer’s patients, with the goal of slowing cognitive decline rather than reversing it. A Phase 3 trial conducted by Cognito Therapeutics involves about 700 participants across 70 sites; earlier feasibility studies showed changes in brain signals and potential slowing of decline, though safety concerns are mostly headaches and the approach is intended to be a low-risk, accessible treatment alongside drugs.

Tiny brain zap nudges people toward generosity, study finds

In a University of Zurich study, 44 volunteers received non-invasive electrical stimulation to the frontal and parietal brain areas while deciding how to split money. When stimulated simultaneously, participants showed a modest but consistent increase in generosity toward an anonymous partner, though effects were short-lived and would require repeated sessions for longer-term change. Researchers say this demonstrates a causal link between these networks and altruistic choices and could inform treatment of social-behavior disorders, with ethical safeguards in place.

Alpha Waves Define the Boundary Between Self and World

Scientists linked alpha-frequency brain activity in the parietal cortex to the sense of body ownership during the rubber hand illusion, and using transcranial alternating current stimulation to speed up or slow these waves altered how real a fake hand felt, suggesting alpha waves help define the brain's body map with potential implications for schizophrenia, phantom limbs, prosthetics, and VR.

Focused Ultrasound Could Pinpoint Where Consciousness Emerges in the Brain

Researchers propose using noninvasive transcranial focused ultrasound to stimulate specific deep-brain regions in healthy subjects, enabling cause‑and‑effect tests of how consciousness arises and where it resides, potentially resolving debates about localized versus network-based origins of conscious experience.
