We describe a method to localize fluorescently tagged proteins in electron micrographs. Fluorescence is first localized using photo-activated localization microscopy on ultrathin sections. These images are then aligned to electron micrographs of the same section.

Plant intercellular connections, the plasmodesmata (Pd), play central roles in plant physiology and plant-virus interactions. Critical to Pd transport are sorting signals that direct proteins to Pd. However, our knowledge about these sequences is still in its infancy. We describe a strategy to identify Pd localization signals in Pd-targeted proteins.
FAQs
Timing, intensity, and direction cues provide complementary information about where a signal originates. Sensory receptors detect these differences, and the brain integrates them before selecting a behavioral response. Because each cue contributes a different spatial feature, changes in their availability or reliability can alter localization performance and produce characteristic shifts in response accuracy, speed, or error patterns.
Multisensory integration allows the brain to combine spatial information from visual, auditory, or other relevant signals rather than interpreting each input in isolation. This integration can be examined by comparing responses to individual sensory modalities with responses to combined stimuli. Such comparisons reveal how sensory information contributes to spatial perception and the resulting behavioral response.
Accuracy shows whether a participant identifies a position correctly, whereas response time indicates how rapidly the spatial judgment is completed. Error patterns add information about systematic or variable distortions in responding. Considering all three measures helps distinguish changes in sensory processing, attention, or decision-related behavior that might produce similar overall accuracy scores.
Localization performance can vary with attention, sensory processing, development, environmental conditions, learning, and neurological dysfunction. These factors may influence how spatial cues are detected, integrated, or translated into action. Measuring both performance level and response patterns across conditions helps researchers determine whether a change reflects altered perception, behavioral adaptation, or a broader change in processing.
Researchers present visual, auditory, or multisensory stimuli and ask participants or experimental subjects to identify the relevant position or source. They then record accuracy, response time, and the pattern of errors. Comparing these outcomes across stimulus types or experimental conditions provides a behavioral measure of spatial perception and sensory processing.
The measure is useful when researchers need to examine spatial perception, attention, sensory processing, navigation, or learning through observable behavior. It can also characterize changes associated with development, environmental conditions, or neurological dysfunction. Visual, auditory, and multisensory tasks allow investigators to study whether these influences affect one sensory system, integration across systems, or the behavioral response.
