Description

Brain imaging experts in Japan built a new head coil to scan awake monkeys with fine detail. Awake scans can show how the primate brain wires itself at rest, which bears on human brain maps. Awake monkeys move and sessions stay short, so signal is weak. The team built a 24-channel coil tuned for a standard scan strength and for fast scan tricks that cut time.

Scans used a blood-volume dye that boosts the signal far past the standard oxygen read. A data clean-up path, adapted from a human brain project, handled motion and layout warps. A trained sorter then stripped out structured noise from the time series. Noise still took more of the signal than brain work did, which the team flags as the next bar. The coil and path open the way to longer awake studies.
