Uncertainty Shapes Neural Dynamics in Motor Cortex During Reaching

The paper examines how uncertainty about movement targets affects neural activity in the motor cortex during reaching tasks in rhesus macaques, finding that PMd shows reduced neural trajectory expansion with higher uncertainty.

Brainwide mesoscale functional networks revealed by focal infrared neural stimulation of the amygdala

The paper uses infrared neural stimulation and fMRI to map mesoscale functional networks in the primate amygdala, revealing distinct connectivity patterns of its nuclei.

Social Status as a Latent Variable in the Amygdala of Observers of Social Interactions

The paper shows that third-party observers infer social status from simulated dyadic interactions and that amygdala neurons encode the status of both interacting individuals.

Interoceptive Signals Bias Decision Making in Rhesus Macaques

This study shows that interoceptive signals from the body influence decision-making in rhesus macaques by altering tolerance for aversive stimuli without affecting reward-seeking behavior.

Detection of latent brain states from baseline neural activity in the amygdala

The paper uses machine learning to decode social vs. non-social context from baseline local field potentials in the amygdala, finding that broad-band information improves decoding accuracy.

A context-dependent switch from sensing to feeling in the primate amygdala

The paper shows that primate amygdala neurons shift from responding to tactile stimuli to reflecting social context during grooming, with baseline firing rate changes indicating affective processing.

Mesoscopic-scale functional networks in the primate amygdala

The paper identifies functionally distinct subnetworks in the primate amygdala using source separation of neural activity across multiple stimuli.
