Pulmonary vein isolation (PVI) with an ablation catheter is a curative treatment for atrial fibrillation (AF). Robotic catheter systems aim to improve catheter steerability. Here, a procedure with a new robotic catheter system is presented. The goal of the procedure is electrical block between pulmonary vein and left atrium.

Source: Muto, A., et al. Ablation of a Neuronal Population Using a Two-photon Laser and Its Assessment Using Calcium Imaging and Behavioral Recording in Zebrafish Larvae. J. Vis. Exp. (2018) In this video, a two-photon laser ablation procedure is demonstrated, enabling the selective destruction of fluorescent neurons in agarose-immobilized zebrafish larvae. High-resolution imaging before and after the procedure confirms efficient neuronal damage, as observed by the absence of fluorescence.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University How do people find objects in cluttered visual scenes? Think, for example, of looking for keys on a messy desk, finding the ripest-looking fruit at the grocery store, locating your car when you can’t quite remember where you parked it, or finding an old friend at an airport exit gate. Clearly, an understanding of visual perception is going to play a role in any answers, and more specifically, an understanding of visual attention...
FAQs
The effect of removing one input is interpreted relative to the complete system and the behavior of other removals. If performance changes substantially for one element, that element may be influential; if several elements produce related or context-dependent effects, the pattern can point to interactions rather than isolated contributions. This helps engineers examine system behavior beyond simple importance rankings.
Keeping the remaining inputs, system configuration, and evaluation conditions unchanged makes the comparison attributable to the ablated feature. Engineers can then measure differences in accuracy, error, efficiency, or reliability without confusing the result with unrelated changes. This control improves the credibility of conclusions about which inputs or components affect successful operation.
Ablation results show which inputs or components contribute meaningful performance and which appear redundant. Engineers can use that evidence to reconsider the feature set, simplify a design, or focus optimization effort on influential elements. The same comparisons also support model interpretation by connecting system outcomes with specific information sources or engineered components.
First, establish performance for the complete system using selected measures such as accuracy, error, efficiency, or reliability. Next, remove, mask, or disable one feature or component while preserving other conditions, then repeat the evaluation. Comparing each altered result with the complete-system baseline identifies performance changes and supports conclusions about contribution, redundancy, or weakness.
A large deterioration suggests that the removed input or component is important for the measured outcome, while little change may indicate limited contribution or redundancy under the tested conditions. Engineers should interpret these results using the chosen metric and the fixed evaluation setup. The findings can guide feature selection, system refinement, and investigation of weaknesses.
The method is useful when engineers need to interpret a model, assess sensor or component value, improve a design, or investigate robustness. It can reveal weaknesses that are hidden in complete-system performance, indicate where additional data collection may help, and show which information is essential for reliable operation. These insights support targeted changes rather than indiscriminate redesign.
