Non-basaltic volcanism is rare on the Moon. The best known examples occur on the lunar nearside in the compositionally evolved Procellarum KREEP terrane. However, there is an isolated thorium-rich area—the Compton–Belkovich thorium anomaly—on the lunar farside for which the origin is enigmatic. Here we use images from the Lunar Reconnaissance Orbiter(More)
UNLABELLED Representations in early visual areas are organized on the basis of retinotopy, but this organizational principle appears to lose prominence in the extrastriate cortex. Nevertheless, an extrastriate region, such as the shape-selective lateral occipital cortex (LO), must still base its activation on the responses from earlier retinotopic visual(More)
The NASA Lunar Reconnaissance Orbiter Camera (LROC) is comprised of three cameras (Figs 1 and 3): a Wide-Angle Camera (WAC) and two identical Narrow Angle Cameras, called NAC-L and NAC-R. The instruments and electronics were built by Malin Space Science Systems with heritage from the successful cameras MARCI and CTX onboard MRO [1]. The WAC is a push-frame(More)
The cortex is a massively recurrent network, characterized by feedforward and feedback connections between brain areas as well as lateral connections within an area. Feedforward, horizontal and feedback responses largely activate separate layers of a cortical unit, meaning they can be dissociated by lamina-resolved neurophysiological techniques. Such(More)
during the β = 0° orbit (M109168446CE, 0° lat, 10.5° E lon). The 689, 604, and 415 nm bands are in red, green, and blue. The high reflectance streak is the opposition surge, which is at a slightly different position in each filter beacuse each filter has a different emission angle. Right: The phase, emission, and incidence angles of the 643 nm band in red,(More)

Introduction: Recent lunar missions provide the planetary science community with vast amounts of new data enabling important insights into the geology and evolution of the Moon on a global scale. Remotely sensed observations of the polar regions reveal the location of persistently illuminated regions and evidence for volatiles captured in cold traps [1-5].(More)
