Is there any research about discrimination of acoustic patterns only different in beat durations and pause durations in rodents,not frequency or dB ?

Heather Ruth Spence

Hi Alican,

Are you interested in the rodents' discrimination ability, or the researchers'?

Here are a couple papers that might lead to some ideas -

Morova et al 2016 "Ultrasound of varying frequencies and variable emotional impact..."

Stewart et al 2015 "Acoustic features of prairie vole USV covary with heart rate"

Thank you Heather. I am interested in creating easily distinguishable sound patterns by using a fixed frequency sound source ( a buzzer) . The only thing i can modulate is beat duration, pause between beats and repeat number of the sound pattern. I am planning to use sound patterns as positive or negative stimuli for goal directed behavior.

Apparently even they can differentiate between long tone with short gap or no gap. In my setup they were not able to differentiate between beats (50ms tone 50 gap*10 times vs 100 ms tone 100 ms gap * times). I had used a buzzer around 3 kHz.
