COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS [PDF]

, 2002
Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The animals’ behavioral changes were then contrasted with those observed earlier (Meunier et al., 1999) in ...

Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting

European Journal of Neuroscience, Volume 63, Issue 1, January 2026.
In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze studies shows this is an outlier: shortcutting has been observed in only a relatively small fraction of experiments.

Rates of agonism among female primates: a cross-taxon perspective [PDF]

, 2013
Agonism is common in group-living animals, shaping dominance relationships and ultimately impacting individual tness. Rates of agonism vary considerably among taxa, however, and explaining this variation has been central in ecological models of female ...

Video‐Sound Recording Devices Reveal Multiple Drivers of Nocturnal Vocalizations in Tibetan Macaques

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates the nocturnal vocal behavior of Tibetan macaques in Huangshan, China, using 4G infrared cameras and passive acoustic monitoring (PAM). Findings reveal a bimodal vocalization pattern (18:00–19:00 and 21:00–23:00), influenced by sex, age, social centrality, kinship, and ecological factors such as wind direction, temperature, and ...

Close encounters of the friendly kind: pacific between‐group interactions in primates

Biological Reviews, Volume 100, Issue 6, Page 2257-2284, December 2025.
ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.
