Aleph Neuro has introduced an innovative 3D representation of the blood vessels in a living human brain, achieved non-invasively from outside the skull. This groundbreaking mapping technique is said to provide one of the most detailed images of its kind to date. In a mere four minutes, the system can visualize significant blood vessels, surface arteries, and even small arterioles. The process begins with the injection of a standard ultrasound contrast agent that contains microbubbles into the bloodstream. An advanced algorithm then tracks these bubbles as they travel through the vessels, compiling millions of data points to create a comprehensive three-dimensional map of cerebral blood flow. Aleph asserts that this method boasts a spatial resolution that is about 100 times greater than traditional CT imaging. This technology holds the potential to pave the way for brain-computer interfaces that operate without the need for implanted electrodes. Aleph intends to leverage this system to develop a compact chip aimed at what the company envisions as a "telepathic future." By monitoring changes in blood flow to specific brain regions as they become active, researchers can indirectly discern brain activity patterns.
