Visual deprivation in adulthood engages presynaptic plasticity of thalamocortical synapses

This study shows that adult mice can exhibit reversible presynaptic plasticity at thalamocortical synapses through visual deprivation and light reintroduction.

Hierarchical Deviant Processing in Auditory Cortex of Awake Mice

This study investigates hierarchical prediction error signaling in the auditory cortex of awake mice by comparing responses to simple and complex sound pattern violations.

Interactive auditory task reveals complex sensory-action integration in mouse primary auditory cortex

The paper shows that some neurons in the mouse primary auditory cortex encode the mismatch between action and sound, revealing hierarchical integration of sensory and action signals.

Direct Extraction of Signal and Noise Correlations from Two-Photon Calcium Imaging of Ensemble Neuronal Activity

This work proposes a method to directly estimate signal and noise correlations from two-photon calcium imaging data without spike deconvolution, validated on simulated and mouse auditory cortex data.

Homeostatic regulation of perisynaptic MMP9 activity in the amblyopic visual cortex

This study shows that LRx in amblyopic mice induces MMP2/9 activity and ECM degradation in V1, enabling synaptic plasticity through homeostatic regulation of proteolysis.

Dipolar extracellular potentials generated by axonal projections

The paper demonstrates that axonal terminal zones generate significant extracellular field potentials with dipolar characteristics and polarity reversal.

Spatial organization of the mouse auditory cortex to sound dynamics revealed using automated image segmentation

The paper uses automated image segmentation to study spatial organization of sound dynamics in mouse auditory cortex, revealing differences in response to sound onset and offset.
