Wireless Compact Neural Interface for Freely Moving Animal Subjects: A Review on Wireless Neural Interface SoC Designs

Neural interfaces play an important role in vital sign monitoring [1], clinical practice [2], and neuroscience frontier research [3] using animal subjects, such as rodents and nonhuman primates [4], [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 [7], [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. © 2009-2012 IEEE.
