Bayesian Nonparametric Identification of Frequency-Selective Neural Oscillatory States

This paper introduces a Bayesian nonparametric method to identify frequency-selective neural oscillatory states without predefining frequency bands or fixing the number of states.

Robustness in Hopfield neural networks with biased memory patterns

The paper studies how pattern bias affects robustness in Hopfield neural networks under different noise types and finds that higher pattern load favors more biased representations.

Two modes of mid-frontal theta suggest a role in conflict and error processing

The paper identifies two distinct modes of mid-frontal theta oscillations during conflict and error processing in cognitive tasks.

Transient beta modulates decision thresholds during human action-stopping

This study uses a race model framework to test how transient beta oscillations modulate decision thresholds during human action-stopping, finding that beta increases thresholds for the Go process more than the Stop process.

Bilateral Intracranial Beta Activity during Forced and Spontaneous Movements in a Hemi-PD Rat Model

The paper evaluates motor impairments and beta oscillations in a 6-OHDA rat PD model, finding high beta power as a biomarker and DBS as a performance enhancer.

Basal ganglia and cortical control of thalamic rebound spikes

This study investigates how correlations in basal ganglia output affect thalamic rebound spikes and motor signal transmission using a Hodgkin-Huxley model.

Occasion setters determine responses of putative dopamine neurons to discriminative stimuli

The paper investigates how putative dopamine neurons in rats respond to discriminative stimuli in a task involving occasion setting, finding heterogeneous single-unit responses rather than population-level changes.

Globus pallidus dynamics reveal covert strategies for behavioral inhibition.

The paper shows that rats use GPe network states to strategically inhibit actions, with specific state-space locations predicting error types during behavioral inhibition.

Abundance compensates kinetics: Similar effect of dopamine signals on D1 and D2 receptor populations

The paper develops a neurochemical model showing D1 and D2 dopamine receptors respond similarly to tonic and phasic signals due to receptor kinetics and abundance.

Sensorimotor Processing In The Basal Ganglia Leads To Transient Beta Oscillations During Behavior

The paper models transient beta oscillations in the basal ganglia using a computational model combined with experimental data from rats performing a task, showing they share mechanisms with pathological beta oscillations in Parkinson's disease.
