Abstract

The common marmoset has received a lot of attention of researchers from many areas in the past years, especially from neuroscience. By hence, currently it's known a lot about the visual system of marmosets, which assembles in many aspects with the genre Macaca and humans. Besides, its small body and brain structures similar to those found in humans, have contributed to establishing this animal as a viable model for visual neuroscience. The attentional neuroscience, as well other areas, would get benefits using the common marmoset as an animal model. In this project, we aim to investigate the performance of common marmosets in a multisensory attentional task. Specifically, we will investigate the possible facilitation on the execution of saccades to the places indicated by spatial auditory cues. For this, we will use a detection task, with auditory cues and visual targets, which has its results well described for humans and rhesus monkey. The behavioral results of this task are characterized by a response facilitation of the animals when spatial auditory cues indicate the correct localization of the visual target. The results from this study will help us to comprehend the capacity and limits of the common marmosets' behavior, as well their viability as an animal model for studying complex cognitive processes, such as attention.
