Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion
0 Views •
2020
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target. At room temperature, a gaseous molecule will experience billions of collisions per second. The mean free path is the average distance a molecule travels between collisions. The mean free path increases with decreasing pressure; in general, the mean free path for a gaseous molecule will be...

Rodents are an appropriate model to investigate the molecular substrates of behavior and complex psychiatric disorders. Brain microinjection in awake rodents can be used to elucidate disease substrates. An efficient and customizable brain microinjection method as well as the execution of an operant paradigm that quantifies motivation is presented.

Design and Analysis of Temperature Preference Behavior and its Circadian Rhythm in Drosophila

2014
We recently identified a novel Drosophila circadian output, temperature preference rhythm (TPR), in which the preferred temperature in flies rises during the day and falls during the night. TPR is regulated independently from another circadian output, locomotor activity. Here we describe the design and analysis of TPR in Drosophila.
FAQs
It compares observable behavioral phenotypes with molecular measurements collected from defined brain regions and across experimental conditions or behavioral states. Concordant changes in gene expression, proteins, metabolites, or signaling pathways can reveal molecular correlates of learning, stress, motivation, or disease. This framework helps clarify how neural circuits respond to experience.
Behavior is associated with molecular changes in particular nervous-system locations, so regional sampling helps relate a finding to relevant neural circuitry rather than treating the brain as uniform. Examining gene expression, proteins, metabolites, and signaling pathways captures several categories of biological information. Together, these readouts provide a broader basis for interpreting behavior-related molecular profiles.
Comparisons identify molecular profiles that differ with learning, stress, motivation, or neurological disease. The contrast can show which genes, proteins, metabolites, or signaling pathways are associated with a particular behavioral state or experimental condition. In neuroscience, this comparative design connects circuit responses to experience with measurable molecular changes rather than relying on behavioral observations alone.
Researchers first characterize behavior through behavioral phenotyping, then measure selected molecular features in defined brain regions. They compare those measurements across experimental conditions or behavioral states and interpret the resulting profiles alongside the behavioral data. This workflow can connect changes in gene expression, proteins, metabolites, or signaling pathways with learning, stress, motivation, or disease-related outcomes.
The approach can incorporate measurements of gene expression, proteins, metabolites, and signaling pathways. These readouts represent different molecular categories that can be examined alongside behavioral phenotypes and regional brain measurements. Comparing the resulting profiles across conditions or behavioral states helps investigators determine which molecular patterns accompany changes in learning, stress, motivation, or neurological disease.
It is useful when investigators need to relate behavior to biological changes associated with learning, stress, motivation, or neurological disease. The resulting profiles can support biomarker development, disease modeling, and intervention design. Because measurements are tied to defined brain regions and behavioral states, the approach also helps frame how neural circuits respond to experience in experimental research.
