Nothing Phone 4a Pro brings subtle upgrades, a cleaner design, and more. But do these changes actually justify their value? Let’s find out in this review.

How is human locomotion visually controlled? Fifty years ago, it was proposed that we steer to a goal using optic flow, the pattern of motion at the eye that specifies the direction of locomotion.

The dorsal raphe nucleus (DRN) serotonergic (5-HT) system has been implicated in regulating sleep and motor control; however, its specific role remains controversial. In this study, we found that ...
