Question
Transcribed Image Text:Standard 7a
Rodents can make vocalizations that humans can hear, such as a squeal. But they also can
communicate during social interactions using ultrasonic vocalizations - vocalizations at a
frequency higher than the human ear is capable of hearing. Sex differences in vocal
communication, similar to observations in songbirds, are observed In rats, with adult male rats
eliciting a typical type of ultrasonic vocalizations not observed in females.
As noted elsewhere in this Problem Set, FOXP2 is involved in the development and neural
control of vocalizations in a broad spectrum of species, including rodents. In humans it is linked
to human speech and language disorders. In rats, FOXP2 has been related to sex-specific
vocalizations, like the male-typical ultrasonic vocalizations. FOXP2 expression in neurons in the
brain is greater in males than females. Further, recent research demonstrated that FOXP2 is a
target of activated androgen receptors (Le specialize receptors that bind androgens such as
testosterone and di-hydrotestoterone) (Bower et al., 2014).
22. Create a model that describes how biological information within a male rat contributes to the
development and production of the behavioral phenotype of male-typical ultrasonic
vocalizations.
As you work through the model, be aware of the the following:
What cell is the emitter/sender?
What cell is the receiver? What is the receptor?
What is the signal?
What biological response is induced by the receiver cell?
How does this biological response contribute to the development and production of
male-typical ultrasonic vocalizations?
