TL;DR: This paper found that superior colliculus (SC) neurons begin discharging seconds before saccade initiation, suggesting involvement in target selection or, alternatively, in postselectional saccades preparation.

TL;DR: The primary motor cortex (M1) is essential for voluntary fine-motor control and is functionally conserved across mammals using high-throughput transcriptomic and epigenomic profiling of more than 450k single nuclei in humans, marmoset monkeys and mice as mentioned in this paper.

TL;DR: This study reveals a unified molecular genetic landscape of cortical cell types that congruently integrates their transcriptome, open chromatin and DNA methylation maps, and establishes a unified and mechanistic framework of neuronal cell type organization that integrates multi-layered molecular genetic and spatial information with multi-faceted phenotypic properties.

TL;DR: Results are consistent with the notion that a restricted network of SC neurons plays a role in the process of saccade target selection, and are particularly strong in a subpopulation of neurons with directional visual responses that have been described previously.

TL;DR: It is concluded that monkeys may employ, in part, a spatially referenced mnemonic strategy for representing perceptual decisions, even when an abstract, categorical representation might appear more likely a priori.
