Polarity-dependent modulation of sleep oscillations and cortical excitability in aging

This study tests the effect of anodal and cathodal so-tDCS on sleep oscillations and cortical excitability in older adults, finding that anodal so-tDCS improves SO-spindle synchrony and cortical excitability, while cathodal so-tDCS does not enhance these measures.

Objects Guide Human Gaze Behavior in Dynamic Real-World Scenes

This paper introduces a computational framework to simulate human gaze behavior in dynamic scenes, showing that object-based attention improves the accuracy of simulated eye movements compared to spatial-based models.

Empirically identifying and computationally modelling the brain-behaviour relationship for human scene categorization

The paper identifies and models the neural and behavioural correlates of scene categorization in humans using EEG data and a recurrent convolutional neural network.

Towards optimization of oscillatory stimulation during sleep

This study investigates how matching stimulation frequency to natural slow oscillations during sleep affects SO-spindle coupling, finding that standardized frequency is more effective than individualized frequency.

Cross-frequency slow oscillation-spindle coupling in a biophysically realistic thalamocortical neural mass model

The paper analyzes a thalamocortical neural mass model to study cross-frequency coupling between slow oscillations and sleep spindles during different cortical activity regimes.

Synchronization through uncorrelated noise in excitatory-inhibitory networks

The paper investigates how uncorrelated noise affects communication between excitatory-inhibitory networks using the PING mechanism, finding that noise can facilitate inter-regional synchronization through reduced intra-network synchronization.

Interrelations between delta waves, spindles and slow oscillations in human NREM sleep and their functional role in memory

This study investigates delta waves, spindles, and slow oscillations in human NREM sleep and their role in memory formation in older adults, finding that the ratio of SO- to delta-nested spindles predicts memory ability.

In V4, pair-wise synchony and correlations depend on the structure of the population code

The paper examines population coding in V1 and V4 of macaques during a visual task, finding that in V4, informative neurons show stronger synchrony and correlations within coding pools than across them.

Learning from invariants predicts upcoming behavioral choice from spiking activity in monkey V1

The paper predicts upcoming behavioral choices from spiking activity in monkey V1 by analyzing the overlap between stimulus and choice information in population vectors.

The paper introduces a model to read-out neural spike trains for stimulus discrimination, showing it outperforms population PSTH in classification and reveals functional subnetworks in V1 and V4.

Weak electric fields promote resonance in neuronal spiking activity: analytical results from two-compartment cell and network models

The paper analyzes how weak electric fields affect neuronal spiking activity using two-compartment neuron models and shows they modulate spiking in specific frequency bands.

Differential polarization of cortical pyramidal neuron dendrites through weak extracellular fields

The paper investigates how weak alternating electric fields affect the subthreshold response of cortical pyramidal neurons, finding frequency resonance in apical dendrites due to morphology and h-type channels.
