This study examines how deep neural networks model 'what' and 'where' in sound localization, finding that 'what' manifolds are geometrically organized and influence 'where' map formation, with implications for understanding brain function.

The paper identifies a new excitatory neuron type in marmoset auditory cortex, characterized by narrow-spike burst firing and distinct response properties.

The paper investigates how marmoset auditory cortex neurons respond to sound locations inside and outside their receptive fields during task engagement, finding increased firing rates outside RFs in certain brain areas.

The paper identifies two voice patches in the marmoset auditory cortex using wide-field calcium imaging that selectively respond to marmoset vocalizations.

This study maps tonotopic organization in awake marmosets using multi-modal imaging and recordings, revealing new gradients not previously described in primate auditory cortex.

This study measures sound localization acuity in common marmosets using operant conditioning, finding minimum audible angles of 13-22 degrees for horizontal and vertical sound locations.

The paper investigates location-specific facilitation in marmoset auditory cortex, finding that repetitive sound stimulation from a single location increases neural firing rates, suggesting a novel form of contextual modulation.

This paper develops a non-invasive optical imaging method to map functional areas of the primate cortex across multiple modalities in awake marmosets.
