“…fMRI in marmosets has also been improved by the development of optimized hardware, such as the radiofrequency coil (Gilbert et al, 2023; Papoti et al, 2013) and optimized marmoset holders and head-fixation chambers to conduct fully awake MRI (Liu et al, 2013; Schaeffer et al, 2019a). In such environments, a variety of task-based assessments have been established to study visual (Cléry et al, 2020; Hung et al, 2015a, b; Schaeffer et al, 2019b; Schaeffer et al, 2020b), auditory (Jafari et al, 2023; Sadagopan et al, 2015; Toarmino et al, 2017), olfactory (Ferris et al, 2001; Ferris et al, 2004), and tactile processing. Furthermore, brain activity in the resting state has been thoroughly investigated (Belcher et al, 2016; Belcher et al, 2013), and a unique feature of the default mode network in marmosets has been demonstrated (Liu et al, 2019).…”
