For the past few years, my sex drive has been lower than it used to be. Even the idea of test driving free vibrators I get from work sometimes feels like more effort than watching 20 minutes of a Netflix show before passing out. Unlike other, similar-looking vibrators, it boasts the use of sonic waves over vibrations, which supposedly reach and stimulate deeper, obscured parts of your clitoris.

While researchers categorize the ultrasonic vocalizations of mice by frequency, it is unclear whether these categories are relevant categories for mouse behavior. Rather, mice may communicate via other properties of vocalizations such as the number of vocalizations as well as via the context of vocalizations. To investigate sex differences in mouse vocalizations after social experiences, Burke and colleagues analyzed vocalizations of 20 male and 20 female mice after they had spent an hour in one of three social contexts: isolation, being with a same-sex mouse, and being with an opposite-sex mouse.

The invention relates to a soft-ware design plan of ultrasonic detecting-monitoring system for non-medical fetus sex, which comprises the following parts: ultrasound pattern collecting module, fetus ultrasound pattern library module, ultrasound pattern processing module, sorter module and evidence logging module. The invention is characterized by the following: the pattern collecting module finishes collecting and transferring automatically to realize digitalization of ultrasound pattern; the fetus pattern library module is comprised of a huge number of typical fetus ultrasound patterns; the ultrasound pattern processing module comprises but does not limit pre-processing pattern algorism, affine inalterability transformation algorithm and extracting characteristic algorism; the sorter module whether or not has capacity of discernment to sexual organ in ultrasound pattern and the algorism comprises but does not limit holding vector machine algorism; the evidence logging module judges based on sorter module to record deed of non-medical fetus sex differentiation. The invention provides a whole soft-ware design plan of ultrasonic detecting-monitoring system for non-medical fetus sex, which inhibits detecting fetus sex for non-medical purpose effectively.

Its closely related family member FOXP2 is involved in speech and language disorder and Foxp2 deficient mice have demonstrated an absence of ultrasonic vocalizations USVs.

House mice Mus musculus emit ultrasonic vocalizations USVswhich are surprisingly complex and have features of bird song, but their functions are not well understood. Previous studies have reported mixed evidence on whether there are sex differences in USV emission, though vocalization rate or other features may depend upon whether potential receivers are of the same or opposite sex. We recorded the USVs of wild-derived adult house mice F1 of wild-caught Mus musculus musculusand we compared the vocalizations of males and females in response to a stimulus mouse of the same- or opposite-sex. We found no differences in the rates of calling between the sexes overall, but mice of both sexes emitted vocalizations at a higher rate and higher frequencies during opposite- compared to same-sex interactions.
