Attention! V1 Neurons Lining Up for Inspection
In this issue of Neuron, Roelfsema and Spekreijse report that macaque V1 neuron responses are correlated with target choice in a task requiring monkeys to attentively trace a line to plan a saccade. These results provide evidence that V1 is actively involved in the interpretation of visual stimuli.
متن کاملMicrotubules: Sizing Up the GTP Cap
The 'GTP cap' of the microtubule has long been postulated to exist, but a recent experiment gives us the first quantitative measurements of the cap size in the cell.
متن کاملMicrotubules: Kar3 Eats up the Track
Molecular motors are quintessential bio-machines found throughout phylogeny. A new application of in vitro assays highlights an unexpected dual functionality for the motor domain of the microtubule-based kinesin-14 type motor protein from budding yeast.
متن کاملLining Up: Survey and Administrative Data Estimates of Wealth Concentration
The Survey of Consumer Finances (SCF) has a dual-frame sample design that supplements a standard area-probability frame with a sample of observations drawn from statistical records derived from tax returns. The tax-based frame is stratified on the basis of a “wealth index” constructed largely from observed income flows, with the intent of heavily oversampling wealthy households. Although the SC...
متن کاملLining-Up Control Strategies for N-trailer Vehicles
Maneuvers performed with tractor-trailers vehicles (N-trailers) belong to the most demanding motion control tasks in the transportation practice. Very frequent maneuvers concern the lining-up process of a vehicle chain, usually as a preliminary stage which prepares the system to subsequent parking/docking maneuvers. The most common lining-up control approach results from utilization of the open...
