Presented here is a protocol to perform comprehensive neonatal echocardiography by trained neonatologists in the neonatal intensive care unit. The trained individuals provide longitudinal assessments of heart function, systemic and pulmonary hemodynamics in a consultative role. The manuscript also describes the requirements to become a fully trained neonatal hemodynamics specialist.

Uncertainty in Measurement: Accuracy and Precision
0 Views •
2020
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value. Suppose a quality control...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory is limited. Throughout most of its history, experimental psychology has focused on investigating the discrete, quantitative limits of memory—how many individual pieces of information a person can remember. Recently, experimental psychologists have also become interested in more qualitative limits—how precisely is information stored? The concept of memory precision can be both intuitive and elusive at once. It is...

This article details intrathecal delivery methods for CNS-targeted therapeutics in adult mice, focusing on protocol precision and enabling repeated injection. It includes findings from a validation study where antisense oligonucleotides reduced mutant SOD1 expression in SOD1-ALS model mice, supporting the utility of the approach in preclinical research on neurodegenerative diseases.
FAQs
These information sources identify a neural substrate from complementary perspectives. Anatomical coordinates locate a brain region, connectivity patterns indicate how that region participates in circuit organization, and cellular or molecular markers distinguish relevant cell populations. Combining them reduces reliance on a single targeting criterion and helps align the selected intervention with both the structure and biology under investigation.
Limiting effects outside the intended substrate improves the connection between an intervention and its observed outcome. If neighboring regions or cell populations are also affected, changes in neural activity or behavior become harder to attribute to the target. Greater spatial and biological specificity therefore strengthens interpretation and supports more reproducible comparisons across controlled experiments.
The targeting logic changes with the level of organization being studied. A brain-region approach emphasizes anatomical coordinates, whereas circuit-focused work also considers connectivity patterns. Cell-population targeting adds cellular or molecular markers to distinguish particular neural elements. These levels can be combined, allowing researchers to relate location, network relationships, and biological identity within one experimental design.
Specificity depends on whether the selected coordinates, connectivity information, and cellular or molecular markers consistently identify the intended neural substrate. The delivery, recording, or stimulation method must also operate under controlled conditions and limit effects on nearby tissue. Considering both spatial placement and biological selectivity helps determine whether the resulting neural or behavioral changes can be interpreted confidently.
A study first identifies the relevant cell population, circuit, or brain region using anatomical, connectivity, and biological information. Researchers then select a suitable delivery, recording, or stimulation approach and apply it under controlled conditions. The resulting neural activity or behavioral outcome can be evaluated in relation to the selected substrate, helping test its functional relevance without repeating the broader definition of the approach.
It is useful when researchers need to connect a defined neural substrate with activity or behavior. In circuit mapping, targeting helps examine relationships among connected structures. In behavior studies, it supports focused evaluation of how selected neural elements relate to observed responses. The resulting spatial and biological specificity makes functional interpretations more focused than approaches that affect broader tissue.
By directing evaluation toward a defined cell population, circuit, or brain region, Precise Targeting helps researchers examine disease-related mechanisms in a focused neural context. The same principle supports targeted assessment of experimental therapies, because outcomes can be considered in relation to the intended substrate and neighboring tissue. This improves interpretability when judging neural or behavioral effects under controlled conditions.
