A Scalable Touchscreen-Based Spatial Working Memory Task for Cross-Species Research

This paper introduces a touchscreen-based spatial working memory task for marmosets and humans, showing that accuracy declines with longer delays and smaller spatial separations, and that these factors interact.

Cognitive strategy accounts for failure on a hippocampal relational memory task in non-human primates

This study shows non-human primates use a habit-based strategy rather than relational memory in a TP task, with no age-related decline in performance.

Parallel patterns of cognitive aging in marmosets and macaques

This study compares age-related working memory deficits in macaques and marmosets, finding similar patterns that support marmosets as a valid model for cognitive aging research.

The Common Marmoset as a Translational Model for Longitudinal Studies of Cognitive Aging and Individual Vulnerability to Decline

The paper develops a cognitive test battery for marmosets to study aging and cognitive decline, finding significant individual variability and domain-specific decline similar to humans.

Domain-specific cognitive impairment reflects prefrontal dysfunction in aged common marmosets

This study shows aged common marmosets exhibit domain-specific cognitive impairments linked to prefrontal cortex dysfunction, similar to humans.
