Insect olfactory systems provide unique opportunities for recording odorant-induced responses in the forms of electroantennograms (EAG) and single sensillum recordings (SSR), which are summed responses from all odorant receptor neurons (ORNs) located on the antenna and from those housed in individual sensilla, respectively.

Drosophila has emerged as a significant model system for dissecting the cellular and molecular underpinnings of behavioral responses to alcohol. Here we present a protocol for the collection of alcohol sensitivity data in a circadian context that can be easily applied to other experiments and is well-suited for undergraduate research.

Preparation of a Micropatterned Substrate to Study Schwann Cell Phenotypes

The video describes the preparation of a micropatterned substrate to study cell phenotype specification. A protein-coated micropatterned PDMS stamp is used to transfer the micropattern on a PDMS-coated coverslip. The coverslip is then treated with a surfactant to hinder cell adhesion at the unwanted surfaces. Cells are then added to settle in the pattern and incubated for further analysis.
FAQs
Moisture conditioning reduces an avoidable source of variation in inhaled-air experiments. Air first encounters a water-based humidifier, or an equivalent moisture-control unit, before reaching the preparation or subject. Maintaining a consistent moisture level helps keep differences in neural measurements more closely tied to the intended inhaled stimulus rather than to changing dryness.
These conditions jointly determine how consistently the experimental preparation encounters the air stream. A regulated flow rate supports repeatable delivery, while limiting temperature and humidity changes reduces environmental fluctuations that could influence neural responses. Controlling them together strengthens comparisons between trials and helps investigators interpret observed changes as responses to the experimental condition.
A stable conditioned airstream provides a consistent background against which inhaled stimuli can be tested. Without that control, dry or fluctuating air may contribute to the measured response and complicate interpretation. By reducing those environmental influences, the system helps distinguish neural activity associated with the stimulus from activity associated with changing airflow conditions.
The setup passes air through a water-based humidifier or another moisture-control unit, establishes the desired regulated flow, and directs the conditioned stream toward the subject or preparation. Researchers also limit changes in temperature and humidity during delivery. These steps create consistent exposure conditions before neural responses to inhaled stimuli are assessed.
The approach is useful when environmental air conditions could affect measurements involving respiration, olfaction, airway sensory pathways, or responses to inhaled stimuli. It can be applied to experiments involving an experimental subject or preparation whenever consistent airflow and moisture are important for comparing neural responses across conditions or trials.
Controlled humidified airflow improves experimental reproducibility by reducing variation caused by dry or unstable air. More consistent conditions make results easier to compare across trials and help researchers evaluate neural responses with fewer environmental confounds. In neuroscience studies, this supports clearer interpretation of measurements related to breathing, olfactory processing, airway sensation, and inhaled stimuli.
