Inbreeding avoidance, competition and natal dispersal in a pair-living, genetically monogamous mammal, Azara’s owl monkey (Aotus azarae)

Royal Society Open Science
Natal dispersal is an important life-history stage influencing individual fitness, social dynamics of groups and population structure. Understanding factors influencing dispersal is essential for evaluating explanations for the evolution and maintenance ...

IN VIVO MAPPING OF CORTICAL COLUMNAR NETWORKS IN THE MONKEY WITH FOCAL ELECTRICAL AND OPTICAL STIMULATION

Frontiers in Neuroanatomy, 2015
There are currently largescale efforts underway to understand the brain as connection machine. However, there has been little emphasis on understanding connection patterns between functionally specific cortical columns.

SPLASh: A software tool for stereotactic planning of recording chamber placement and electrode trajectories

Frontiers in Neuroinformatics, 2011
While computer-aided planning of human neurosurgeries is becoming more and more common, animal researchers still largely rely on paper atlases for planning their approach before implanting recording chambers to perform invasive recordings of neural ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Recovering stimulus locations using populations of eye-position modulated neurons in dorsal and ventral visual streams of nonhuman primates

Frontiers in Integrative Neuroscience, 2014
We recorded visual responses while monkeys fixated the same target at different gaze angles, both dorsally (lateral intraparietal cortex, LIP) and ventrally (anterior inferotemporal cortex, AIT).

Causal Evidence for Induction of Pessimistic Decision-Making in Primates by the Network of Frontal Cortex and Striosomes

Frontiers in Neuroscience, 2021
Clinical studies have shown that patients with anxiety disorders exhibited coactivation of limbic cortices and basal ganglia, which together form a large-scale brain network.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Spatially Specialized Nasopharynx–Rectal Microbiomes in Golden Snub-Nosed Monkeys (Rhinopithecus roxellana)

Biology
Background: Understanding the nasopharyngeal (NAS) and rectal (INT) microbiomes is critical to maintain host health. However, their functional roles in shaping microbial network structure and niche differentiation remain unexplored in most animal species,

Cortical Motor Organization, Mirror Neurons, and Embodied Language: An Evolutionary Perspective

Biolinguistics, 2012
The recent conceptual achievement that the cortical motor system plays a crucial role not only in motor control but also in higher cognitive functions has given a new perspective also on the involvement of motor cortex in language perception and ...

Transduction of Craniofacial Motoneurons Following Intramuscular Injections of Canine Adenovirus Type-2 (CAV-2) in Rhesus Macaques

Frontiers in Neuroanatomy, 2019
Reliable viral vector-mediated transgene expression in primate motoneurons would improve our ability to anatomically and physiologically interrogate motor systems.
