This paper introduces a framework combining point processes with reinforcement learning to analyze individual and group learning in mice, finding that group effects are twice as strong as individual learning.

The paper introduces a reinforcement learning model to study social influence in mice, revealing how group structure and individual learning strategies vary based on goal alignment and motivational states.

This paper introduces EVOX, a platform for mapping synaptic plasticity and LTP in hippocampal networks, showing high-frequency stimulation induces network-wide LTP.

The paper shows that local thalamic LFP can be reliably recovered using kCSD, even without concurrent cortical recordings, by removing a negative component from cortex.

kCSD-python provides a Python package for reliable current source density estimation with quality control techniques and diagnostic tools.

This study identifies nonmotor symptoms linked to early dopaminergic neuron loss in a mouse Parkinson's disease model.

The paper characterizes the structural properties of the marmoset monkey's neocortical connectome using retrograde tracer data, revealing heterogeneity, functional specificity, and hierarchical organization.

The paper analyzes what information about brain current sources can be recovered or remains unobservable using extracellular multielectrode recordings, across different experimental setups.

This study identifies ketamine-xylazine-induced high frequency oscillations (HFO) in the olfactory bulb of rats and cats, showing they depend on nasal airflow and local dendrodendritic interactions, not gap junctions or the piriform cortex.

The paper investigates how social information about rewards influences behavior in mice, showing individual differences and the role of neuronal plasticity in adaptation.

The paper uses whole-brain imaging and c-Fos analysis in mice to study changes in brain networks during alcohol reexposure in a binge-like drinking model.

The paper creates a 3D marmoset cortex template from 20 brains, providing probabilistic localization of cytoarchitectural areas and spatial transformations to other templates.

This study shows that nasal respiration is required for ketamine-induced high-frequency oscillations and hyperactivity in rats, with HFOs coupled to theta-frequency sniffing.

The paper confirms direct, nonreciprocal auditory projections to V1 in marmoset monkeys, supporting early audiovisual integration in primates.

The paper estimates transmembrane current distribution in a neuron with known morphology using extracellular recordings and simulations.

The paper derives and corrects analytical formulas for scalp potentials in the four-sphere EEG head model and compares them with FEM simulations.

This paper introduces a clustering-based analysis of rat movement patterns in the Active Allothetic Place Avoidance task, identifying six new movement motifs affected by silver nanoparticles.
