Although the phasic activity of midbrain dopamine neurons is known to represent reward values, these neurons displayed a tonic firing mode to continuously track reward values changing moment-by-moment.

Detailed quantification of macaque facial behavior reveals a positive link between social and communicative complexity, and helps us to better understand the evolution of animal communication.
Across primates, volumes of specific brain regions relate to specific socio-ecological factors, bridging the gap between neuro-cognitive operations from laboratory studies and challenges primates face in their natural environment.

Modern human diet patterns alter primate behavior and monocyte gene expression leading to monocyte polarization–experimental evidence of the evolutionary mismatch hypothesis.

Without specific training, young chicks represent the absence of objects, showing that the concept of 'nothing' is available to nonhuman animals and does not require linguistic tools, such as negation.

Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.
A decoding-based, state-space reconstruction reveals that neurons in macaque IT cortex change the structure of their collective attractor dynamics depending on task contexts.

A comprehensive modeling approach reconciles experimental observations with classic plasticity mechanisms in the cerebellar cortex, demonstrating how learning-related changes in neural activity can appear to contradict the sign of the underlying plasticity when feedback is present.
