Population Scale Analysis of Centromeric Satellite DNA Reveals Highly Dynamic Evolutionary Patterns and Genomic Organization in Long-Tailed and Rhesus Macaques

open access: yesCells, 2022
Centromeric satellite DNA (cen-satDNA) consists of highly divergent repeat monomers, each approximately 171 base pairs in length. Here, we investigated the genetic diversity in the centromeric region of two primate species: long-tailed (Macaca ...

The hemodynamic initial-dip consists of both volumetric and oxymetric changes reflecting localized spiking activity

open access: yesFrontiers in Neuroscience, 2023
The initial-dip is a transient decrease frequently observed in functional neuroimaging signals, immediately after stimulus onset, believed to originate from a rise in deoxy-hemoglobin (HbR) caused by local neural activity.

Monkey metacognition could generate more insight [PDF]

open access: yesAnimal Behavior and Cognition, 2019
Monkeys demonstrate metacognition by avoiding memory tests when they forget, seeking information when ignorant, and gambling sensibly after making judgments. Some of this metacognition appears to be based on introspection of private mental states.

Familiarity, Active Memory And Pressure During A Delayed Matching-To-Sample Task In Tufted Capuchin Monkeys (Sapajus [Cebus] Apella) [PDF]

open access: yesAnimal Behavior and Cognition
Delayed matching-to-sample (DMTS) tasks are commonly used in the field of comparative cognition to study memory, including working memory. However, specific task demands vary across studies and species, and as such, DMTS tasks may engage different memory
