Source: Elise S.D. Buki, Danielle N. Beatty, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT The laser flash method (LFA) is a technique used to measure thermal diffusivity, a material specific property. Thermal diffusivity (α) is the ratio of how much heat is conducted relative to how much heat is stored in a material. It is related to thermal conductivity (), how much heat is transferred through a material due to a temperature...

Photolysis of caged compounds allows the production of rapid and localized increases in the concentration of various physiologically active compounds. Here, we show how to obtain patch-clamp recordings combined with photolysis of caged cAMP or caged Ca for the study of olfactory transduction in dissociated mouse olfactory sensory neurons.

The biarsenical dyes FlAsH and ReAsH bind specifically to tetracysteine motifs in proteins and can selectively label proteins in live cells. Recently this labeling strategy has been used to develop sensors for different protein conformations or oligomeric states. We describe the labeling approach and methods to quantitatively analyze binding.

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
FAQs
The comparison focuses on whether an apparent flash corresponds to light activating the visual system or occurs without a matching external stimulus. Researchers examine the reported appearance, timing, and surrounding context, then relate those features to observed responses. This helps separate stimulus-driven perception from internally generated visual events without relying on appearance alone.
A flash’s form, duration or timing, and circumstances provide complementary information about the experience. Examining these features together can reveal meaningful differences that a single description might miss. Context also helps researchers interpret whether a report is associated with an external visual event, a perceptual process, or a behavioral response occurring around the experience.
Behavioral responses provide an observable counterpart to a subjective visual report. Researchers can compare what participants say they experienced with how they respond, particularly when the task involves attention, sensory processing, or visually guided behavior. Agreement or divergence between reports and actions can clarify how a brief visual event influences perception and behavior.
A useful comparison records how each flash appears, when it occurs, the context in which it is reported, and what behavioral effect follows. Keeping these dimensions distinct allows researchers to compare experiences systematically rather than treating all light-like reports as equivalent. The resulting pattern can support more careful interpretation of perception and response data.
In behavioral research, the approach connects subjective reports with observable responses to investigate attention, sensory processing, and perception. Researchers can compare how different visual experiences are described and how they affect behavior. This makes the method useful for examining the relationship between what participants report seeing and the actions or responses that follow.
Comparisons can show whether a brief visual experience is associated with a measurable change in behavior, such as a response linked to visual guidance. Interpreting reports alongside actions helps researchers study how perception contributes to behavior. It also provides a way to examine differences between experiences that appear externally stimulated and those generated within the visual system.
