1. Humans tend to walk in circles as directed by memorized visual locations at large distances
Human veering while walking blindfolded or walking straight without any visual cues has been widely studied over the last 100 years, but the results are still controversial. The present study attempted to describe and understand the human ability to maintain the direction of a trajectory while walking without visual or audio cues with reference to a proposed

2. Influência da orientação espacial e do controle postural na locomoção de idosos / The influence of spatial orientation and postural control during elderly locomotion
No andar, o risco de quedas em idosos é maior. O objetivo é estudar o risco de quedas na locomoção sem visão e a relação entre orientação espacial, veering e controle postural. Participaram 27 adultos (25,2±4,5 anos, 1,68±0,10m, 63,8±10,3kg); 27 idosos AF (72,1±4,3 anos, 1,60±0,09m, 68,5±13kg); 12 idosos RQ (72,3±6 anos, 1,57±0,08m, 67,4±10

3. Eye-Hand Coordination During Target Selection in a Pop-Out Visual Search
We examined the coordination of saccades and reaches in a visual search task in which monkeys were rewarded for reaching to an odd-colored target among distractors. Eye movements were unconstrained, and monkeys typically made one or more saccades before initiating a reach. Target selection for reaching and saccades was highly correlated with the hand and eye

4. Positional variations in germinal cell growth in pigment-chimeric eyes of Xenopus: posterior half of the developing eye studied in genetic chimerae and in computer simulations.
Growth of germinal cells at different angular positions within the posterior portion of the embryonic frog eye has been examined by orthotopically transplanting small groups of germinal cells from pigmented (stage 30-38) donor embryos into albino (stage 28-36) hosts and then serially photographing the polyclonal-cell progeny domain (typically a black sector)
