using animal subjects, such as rodents and nonhuman primates

[5]
. Recently, neuroscientists have shown increasing interest in behavioral analysis of social situations with a single or multiple freely moving animals, which has been listed as a key investment by the NIH in 2023
[6]
. Among those popular laboratory animals, marmosets are increasingly favored by researchers because of their small size, short sexual maturity, complex social patterns, and similarity to human beings

,
[8]
. A number of marmoset social behaviors, such as gaze following
[9]
, antiphonal calling
[10]
, and scent marking
[11]
, have been studied with neural signal acquisition and/or stimulation to affect the behavior of the freely moving marmoset at the same time.
