The Posterior Parietal Cortex Remaps Touch into External Space

See the paper

Elena Azañón, Matthew R. Longo, Salvador Soto-Faraco, Patrick Haggard

Localizing tactile events in external space is required for essential functions such as orienting, haptic exploration, and goal-directed action in peripersonal space. In order to map somatosensory input into a spatiotopic representation, information about skin location must be integrated with proprioceptive information . . . → Read More: The Posterior Parietal Cortex Remaps Touch into External Space

Magnetoreception of Directional Information in Birds Requires Nondegraded Vision

See the paper

Katrin Stapput, Onur Güntürkün, Klaus-Peter Hoffmann, Roswitha Wiltschko, Wolfgang Wiltschko

The magnetic compass orientation of birds is light dependent [1,2]. The respective directional information, originating in radical pair processes [3,4,5], is mediated by the right eye [6]. These findings suggest possible interactions between magnetoreception and vision, in particular with the perception of contours, . . . → Read More: Magnetoreception of Directional Information in Birds Requires Nondegraded Vision

The Function of Bilateral Odor Arrival Time Differences in Olfactory Orientation of Sharks

Jayne M. Gardiner, Jelle Atema. The direction of an odor signal source can be estimated from bilateral differences in signal intensity and/or arrival time. The best-known examples of the use of arrival time differences are in ac…. . . . → Read More: The Function of Bilateral Odor Arrival Time Differences in Olfactory Orientation of Sharks

AKT and TOR Signaling Set the Pace of the Circadian Pacemaker

Xiangzhong Zheng, Amita Sehgal. The circadian clock coordinates cellular and organismal energy metabolism [1]. The importance of this circadian timing system is underscored by findings that defects in the clock cause deregulatio…. . . . → Read More: AKT and TOR Signaling Set the Pace of the Circadian Pacemaker

Clock and cycle Limit Starvation-Induced Sleep Loss in Drosophila

Alex C. Keene, Erik R. Duboué, Daniel M. McDonald, Monica Dus, Greg S.B. Suh, Scott Waddell, Justin Blau. Neural systems controlling the vital functions of sleep and feeding in mammals are tightly interconnected: sleep deprivation promotes feeding, wh… . . . → Read More: Clock and cycle Limit Starvation-Induced Sleep Loss in Drosophila

Perisaccadic Stereo Depth with Zero Retinal Disparity

Zhi-Lei Zhang, Christopher R.L. Cantor, Clifton M. Schor. When an object is viewed binocularly, unequal perspective projections of the two eyes’ half images (binocular disparity) provide a cue for the sensation of stereo depth. For almost 200 years, … . . . → Read More: Perisaccadic Stereo Depth with Zero Retinal Disparity
