Transitive reasoning as linear classification

This paper reframes transitive inference as a linear classification problem using least-squares estimation, showing it can reproduce key empirical features of TI without explicit assumptions about transitivity.

Alteration of Water Exchange Rates Following Focused Ultrasound-Mediated BBB Opening in the Dorsal Striatum of Non-Human Primates: A Diffusion-Prepared pCASL Study

This study uses DP-pCASL to measure BBB water exchange rates before and after FUS-mediated BBB opening in non-human primates, finding localized decreases and global increases in Kw.

Learning decouples accuracy and reaction time for rapid decisions in a transitive inference task

This study applies a drift diffusion model to analyze decision-making dynamics in a transitive inference task, showing stable reaction times despite improved accuracy during learning.

Single-Neuron Encoding of Learnability in the Dorsal Anterior Cingulate Cortex

The paper shows that neurons in the dorsal anterior cingulate cortex encode the ability to detect learnable associations in a task involving transitive inference.

Portable transcranial therapeutic ultrasound enhances targeted gene delivery for Parkinson's disease: from rodent models to non-human primates

Portable therapeutic ultrasound enhanced AAV9 delivery to the brain in mice and rhesus macaques compared to systemic injection alone.

A mathematical theory of relational generalization in transitive inference

The paper develops a mathematical framework to explain how learning models, including neural networks, can perform transitive inference through statistical principles and representation learning.

Emergent neural dynamics and geometry for generalization in a transitive inference task

This paper develops and tests neural networks that perform transitive inference, showing they generalize and exhibit behaviors similar to humans, while also revealing inconsistencies between human behavior and certain network solutions.

Alteration of functional connectivity in the cortex and major brain networks of non-human primates following focused ultrasound exposure

This study compares the effects of focused ultrasound alone versus with microbubbles on functional connectivity in non-human primate brains.

Long Term Study of Motivational and Cognitive Effects of Low-intensity Focused Ultrasound Neuromodulation in the Dorsal Striatum of Nonhuman Primates

Neuronal responses in posterior parietal cortex during learning of implied serial order

This study shows that posterior parietal cortex neurons in monkeys represent ordinal ranks of stimuli during serial learning, supporting a virtual workspace model over associative learning.

Focused ultrasound enhances sensorimotor decision-making in monkeys

This study shows that focused ultrasound improves visual-motor decision-making in monkeys and interacts with haloperidol, suggesting a role for the dorsal striatum in decision-making.

Learning In Spike Trains: Estimating Within-Session Changes In Firing Rate Using Weighted Interpolation

This paper introduces ARRIS, a method to estimate trial-by-trial firing rate changes during learning using weighted interpolation and reversible-jump MCMC, enabling real-time analysis of neural activity.
