The Song of Mice: Exploring Communication through Ultrasonic Vocalizations

The video discusses how researcher Tim Holly discovered that male mice sing in the presence of female mice. These high-pitched songs are inaudible to humans but can be recorded using sensitive microphones. Holly's computer program makes these songs audible, revealing various syllable types. By studying these songs, researchers aim to gain insights into the human brain.

What triggers the male mouse to start singing?

• The presence of a female mouse

• The presence of another male mouse

• The presence of food

• The presence of a predator

What type of equipment is used to record the mouse's singing?

• A stethoscope

• A camera with a zoom lens

• A regular microphone

• A microphone sensitive to ultrasound

How are the recorded mouse songs made audible to humans?

• By translating the sounds into music notes

• By amplifying the sound

• By using a computer program

• By slowing down the recording

What is the nature of the mouse songs?

• They mimic human speech

• They are a single continuous tone

• They are random noises

• They consist of several different syllable types

What do researchers hope to learn by studying mouse songs?

• The lifespan of mice

• Insights into the human brain

• The dietary habits of mice

• The migration patterns of mice
