Auditory-motor synchronization determines the use of predictions in music perception

The paper investigates how auditory-motor synchronization influences neural tracking of rhythmic and melodic predictions during music listening, finding stronger tracking of rhythmic predictions in individuals with higher synchronization.

Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

The paper develops a computational model of the fronto-parietal network to show how interacting rhythms enhance visual target detection sensitivity during sustained attention.

Differential contributions of synaptic and intrinsic inhibitory currents to speech segmentation via flexible phase-locking in neural oscillators

The paper investigates how synaptic and intrinsic inhibitory currents contribute to flexible phase-locking in neural oscillators, enabling speech segmentation by identifying vocalic nuclei.

A biophysical model of striatal microcircuits suggests gamma and beta oscillations interleaved at delta/theta frequencies mediate periodicity in motor control

This paper proposes a biophysical model of striatal microcircuits showing how dopamine modulates gamma and beta oscillations interleaved at delta/theta frequencies to enable periodic motor control.

Flexible reset and entrainment of delta oscillations in primate primary auditory cortex: modeling and experiment

The paper shows how delta oscillations in primate auditory cortex are reset and entrained by auditory stimuli, using experimental data and a computational model.

Biased competition in the absence of input bias: predictions from corticostriatal computation

The paper presents a corticostriatal model showing how biased competition can occur without input bias through physiological asymmetries in striatal neurons.

Modeling the schizophrenias: subunit-specific NMDAR antagonism dissociates frontal δ and hippocampal θ modulation of ~140 Hz oscillations

This study shows that NR2A-specific NMDAR antagonism increases delta-HFO coupling and decreases theta-HFO coupling, suggesting frontal hyperfunction and hippocampal hypofunction in schizophrenia-like states.

Striatal cholinergic receptor activation causes a rapid, selective, & state-dependent rise in corticostriatal β activity.

This study shows that activating striatal cholinergic receptors increases beta oscillations in the corticostriatal loop, with directional connectivity and subband-specific effects.
