Functional correlates of immediate early gene expression in mouse visual cortex

The paper examines IEG expression patterns in mouse visual cortex after visual and visuomotor experiences, finding differential IEG expression linked to activity types.

Expression of c-Fos and Arc in hippocampal region CA1 marks neurons that exhibit learning-related activity changes

The paper uses two-photon imaging in transgenic mice to study how IEG expression and neural activity change in CA1 during learning, finding a correlation between IEG levels and learning-related activity changes.

GABAergic neurons in the olfactory cortex projecting to the lateral hypothalamus in mice

The paper identifies a novel GABAergic neuron population in the olfactory cortex of mice that project to the lateral hypothalamus and integrate olfactory and top-down inputs.

Locally coordinated synaptic plasticity shapes cell-wide plasticity of visual cortex neurons in vivo

The paper shows that local synaptic plasticity, mediated by Arc, coordinates potentiation and depression of adjacent spines to shape functional neuronal responses in vivo.

Arc Restores Juvenile Plasticity In Adult Mouse Visual Cortex

This study shows that increasing Arc expression in adult mice restores juvenile-like plasticity in the visual cortex, suggesting Arc plays a key role in age-related declines in neural plasticity.
