SimulScan and Partial Least Squares: Visualizing swallowing through functional and dynamic imaging correlations

This paper introduces an updated SimulScan system with partial least squares correlation to study swallowing by linking biomechanical and brain activity data.

Interoception Network in the Rat Brain

This study identifies an interoception network in the rat brain that is dynamically regulated by visceral inputs and depends on vagus nerve signaling.

Magnetic Resonance Imaging of Gastric Motility in Conscious Rats

This paper demonstrates GI MRI in conscious rats, showing faster gastric emptying and stronger peristalsis compared to anesthetized rats.

In vivo Tracing of the Ascending Vagal Projections to the Brain with Manganese Enhanced Magnetic Resonance Imaging

This study uses MEMRI to trace vagal afferent projections to the brainstem and assess their functional dependence on VNS in rats.

The vagus nerve mediates the stomach-brain coherence in rats

This study investigates stomach-brain coherence in rats using fMRI and gastric slow wave recordings, finding that vagus nerve activity mediates this coherence, which varies between fasting and fed states.

Gastric Neurons in the Nucleus Tractus Solitarius are Selective to the Orientation of Gastric Electrical Stimulation

The paper investigates how gastric electrical stimulation (GES) orientation affects neural responses in the nucleus tractus solitarius (NTS) in rats, finding orientation-specific activation of gastric neurons.

Connecting Concepts in the Brain by Mapping Cortical Representations of Semantic Relations

This study maps cortical representations of semantic relations using fMRI data, showing that semantic categories and relations are encoded in overlapping patterns across brain networks.

Task-Evoked Functional Connectivity Does Not Explain Functional Connectivity Differences Between Rest and Task Conditions

The paper investigates how task-evoked functional connectivity differs from resting-state connectivity and finds that spontaneous networks, not task-evoked ones, mainly explain these differences.

Deep Recurrent Neural Network Reveals a Hierarchy of Process Memory during Dynamic Natural Vision

This paper introduces a deep recurrent neural network to model process memory in visual processing and shows it better predicts cortical responses to natural movies than a standard CNN.

Vagal nerve stimulation triggers widespread responses and alters large-scale functional connectivity in the rat brain

This study uses fMRI to show that vagus nerve stimulation activates 15 out of 20 brain networks in rats and alters large-scale functional connectivity.

Musical Imagery Involves the Wernicke’s Area in Bilateral and Anti-Correlated Network Interactions in Musicians

This study investigates how musicians process musical imagery compared to actual music perception, finding distinct network interactions involving Wernicke’s area.

Deep Residual Network Reveals a Nested Hierarchy of Distributed Cortical Representation for Visual Categorization

The paper uses a deep residual network to map cortical representations of 64,000 visual objects, revealing a nested hierarchy organized by category specificity and spatial scale.
