DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.
Following targeted motor and sensory reinnervation, a procedure that reroutes residual limb nerves to intact muscles and skin in amputees, the brain remaps both motor and sensory pathways. Additionally, researchers note, TMSR may help counteract poorly adapted cortical plasticity following amputation.
Researchers create a map of vision in the brain based upon an individual's brain structure, even for people who cannot see. Their result can, among other things, guide efforts to restore vision using a neural prosthesis that stimulates the surface of the brain.
Using transcranial alternating current stimulation, researchers were able to influence the activity of specific brain areas and manipulate the abilities processed by them. Findings suggest tACS could be used to improve, direct, and attenuate the flow of information in the brain.
