Ultrasonic vocalizations (USVs) in mice differ depending on age, sex, condition, and genetic background. Using two ultrasound emitters broadcasting simultaneously in different locations, this two-choice test can evaluate murine recognition and preference responses to different characteristics of USVs.

Peptide adsorption to plasticware during traditional tip-based serial dilutions can significantly impact potency determination and confound the understanding of structure-activity relationships used for lead identification and lead optimization phases of drug discovery. Here methods for automated acoustic non-contact serial dilution of peptide samples are described.

We demonstrate a storable, transportable lipid bilayer formation system. A lipid bilayer membrane can be formed within 1 hr with over 80% success rate when a frozen membrane precursor is brought to ambient temperature. This system will reduce laborious processes and expertise associated with ion channels.
FAQs
It coordinates stimulus files with an experimental schedule so playback begins under predefined conditions and follows a consistent sequence. This control keeps stimulus onset, duration, repetition, and intensity aligned across trials. As a result, researchers can compare behavioral or physiological responses more reliably because differences in stimulus delivery are reduced rather than introduced by manual timing.
The system can standardize several features that strongly affect experimental comparisons, including stimulus intensity, duration, order, and number of repetitions. Researchers define these parameters before or during the experimental schedule, allowing the same playback pattern to be delivered across subjects or conditions. This consistency helps separate responses to the sensory stimulus from variation caused by delivery differences.
Synchronized playback and recording links each sensory event to the corresponding behavioral or physiological response. Researchers can therefore determine which response occurred after a particular stimulus, sequence position, or repetition. Precise alignment supports comparisons across trials, subjects, and experimental conditions, making it easier to interpret neural or behavioral changes in relation to controlled sensory events.
Manual presentation can introduce researcher-dependent variation in timing, sequence, intensity, duration, or repetition. An Automated Playback System applies programmed settings and schedules instead, reducing opportunities for inconsistent delivery and human error. The resulting standardization improves reproducibility and makes repeated trials more comparable, particularly when experiments require many presentations or carefully controlled stimulus sequences.
Researchers prepare the prerecorded sensory files, specify the playback schedule and stimulus conditions, and program the system to trigger delivery at defined points in the experiment. They then coordinate playback with behavioral or physiological recording and compare responses across trials or subjects. The workflow is useful when consistent sequence, timing, intensity, duration, and repetition are required.
This approach is especially useful when researchers need repeated, precisely comparable sensory presentations while measuring behavior or physiology. It supports studies of sensory processing, neural responses, learning, communication, and behavior in laboratory models. By applying the same schedule across experimental conditions, the system helps investigators evaluate response differences without relying on variable manual stimulus delivery.
The setup supports comparisons of behavioral and physiological responses associated with controlled sensory events. Researchers can examine differences across trials, subjects, stimulus repetitions, or experimental conditions while retaining consistent delivery parameters. In neuroscience, these comparisons can inform investigations of sensory processing, neural responses, learning, communication, and behavior, depending on the recorded response and study design.
