Ordinal position in auditory sequences is encoded in population dynamics in macaque frontal cortex

The paper shows that macaque frontal cortex encodes ordinal position in auditory sequences through population dynamics, while auditory cortex encodes stimulus identity.

Selective enhancement of fronto-temporal mechanisms for adaptive memory

This study uses transcranial ultrasound stimulation to enhance memory performance in macaques by targeting specific fronto-temporal brain regions.

Effect of fluid control on the affective state of laboratory macaques

This study investigates the effect of fluid control on the affective state of laboratory macaques and finds no significant impact on their psychological well-being.

Selective attention network in naturalistic auditory scenes is object and scene specific

This study investigates how selective attention modulates neural representations in the auditory cortex during naturalistic sound scenes, showing context-dependent prioritization of object-specific or category-level features.

Brain Charts for the Rhesus Macaque Lifespan

This study creates normative brain growth charts for rhesus macaques across their lifespan using MRI data, revealing developmental milestones and cross-species comparisons with humans.

The gene expression signature of electrical stimulation in the human brain

This study identifies the gene expression changes in the human brain following electrical stimulation, revealing non-neuronal cell involvement and a conserved gene signature.

Distribution of multi-unit pitch responses recorded intracranially from human auditory cortex

This study records multi-unit pitch responses from human auditory cortex and finds they are distributed across Heschl's gyrus, not localized to a specific region.

Immediate neural network impact after the loss of a semantic hub

This study examines the neural impact of disconnecting a semantic hub in the human brain and finds specific network changes and partial compensation.

Common Fronto-temporal Effective Connectivity in Humans and Monkeys

The paper identifies common effective connectivity patterns between auditory cortex and fronto-temporal regions in humans and monkeys using functional imaging and electrical stimulation.

Human es-fMRI Resource: Concurrent deep-brain stimulation and whole-brain functional MRI

The paper presents a human es-fMRI resource with data from 26 patients undergoing deep-brain stimulation and whole-brain functional MRI, providing raw and preprocessed data for analysis.

An open resource for nonhuman primate imaging

The paper introduces PRIME-DE, an open resource for non-human primate MRI data, aggregating 13 datasets from 11 sites across 98 macaques.
