Structural Analysis of the Victoria Quadrangle Fault Systems on Mercury: Timing, Geometries, Kinematics, and Relationship with the High-Mg Region
Three nonparallel fault systems occur in the Victoria quadrangle of Mercury. The most
prominent system (Victoria system) includes the NNW‐SSE trending Victoria Rupes‐Endeavour
Rupes‐Antoniadi Dorsum (VEA) array, one of the major fault alignments on the planet, and shorter parallel
fault arrays. West and northwest of the Victoria system, two additional fault systems with NE‐SW (Larrocha
system) and NW‐SE (Carnegie system) trends, are found. The timing analysis reveals that the three
systems are coeval and were active until ~3.7 Ga. Measures of rim offset within faulted craters on the VEA
array and on Carnegie Rupes segment of the Carnegie system were used to derive the kinematics of faults
and to perform a finite stress inversion, which provides an ENE‐WSW trending regional shortening axis.
Results of the stress inversion and age relationships, together with geometrical and morpho‐structural
observations, suggest that the NE‐SW and NW‐SE systems acted as right‐transcurrent and
left‐transpressional, respectively, at the time when the computed strain field was active. The distribution of
the three systems spatially coincides with the boundaries of the high‐Mg region and of other regional
geochemical terranes. Lateral geomechanical variation of the crust combined with tidal despinning and
global contraction processes drove the localization and slip pattern of faults in a kinematically consistent
displacement field. Moreover, crustal heterogeneities controlled the lateral changes in density and spacing of
fault segments along the VEA. Following the demise of faulting, the established lateral variation of geometry
along the VEA favored the growth of volcanic vents at high‐permeability segment boundaries

Vision Assessments and Interventions for Infants 0-2 Years at High Risk for Cerebral Palsy: A Systematic Review
We performed a systematic review and evaluated the level of evidence of vision interventions and assessments for infants at high risk for or with a diagnosis of cerebral palsy from zero to two years of age. Articles were evaluated based on the level of methodologic quality, evidence, and clinical utilization. Thirty publications with vision assessments and five with vision interventions met criteria for inclusion. Assessments included standard care neuroimaging, electrophysiology, and neuro-ophthalmologic examination techniques that are utilized clinically with any preverbal or nonverbal pediatric patient. The overall level of evidence of interventions was strong for neuroprotective interventions such as caffeine and hypothermia but weak for surgery, visual training, or developmental programs. There are few evidence-based interventions and assessments that address cerebral/cortical visual impairment-related needs of infants and toddlers at high risk for or with cerebral palsy. Recommendation guidelines include the use of three types of standard care methodologies and two types of protective interventions
Anterior intraparietal cortex codes complexity of contralateral observed hand movement
Human and monkey studies clearly show that the anterior intraparietal area (AIP)
is crucial for hand-related visuomotor transformations. Human AIP activates also
during observation of hand actions, involving it in the mirror system. It is not
known, however, whether its activation can also reflect a difference in the
complexity of the observed action. In the present study we used functional
magnetic resonance imaging (fMRI) to explore the activation of human area AIP
during the observation of complex object-manipulation tasks (e.g. inserting a key
in a lock and turning it) as compared to simple tasks (whole hand grasping of an
object) executed with the left and the right hand in a first person perspective.
The results show that, in general, both complex and simple tasks produced an
activation of the fronto-parietal mirror system and that the activity of AIP in
each hemisphere was higher during observation of the contralateral hand (hand
identity effect). A Region-Of-Interest (ROI) analysis of the parietal activations
responding to hand identity showed that each AIP was more active during the
observation of complex with respect to simple tasks. In the right AIP this effect
was stronger during observation of the contralateral hand, in the left AIP was
strong during observation of both hands. This complexity-related property was not
observed in the other activated areas. These findings support the concept that
the observation of motor acts retrieves the internal representation of those same
acts in the observer's motor system (direct-matching hypothesis based on the
mirror neuron mechanism)
