The geometry of context-dependent biased decisions during learning

This study shows how reward context is encoded through geometric shifts in neural representations, enabling rapid decision adjustments during learning.

Adaptation shapes the representational geometry in mouse V1 to efficiently encode the environment

The paper shows adaptation increases discriminability of frequent stimuli in mouse V1 by reshaping population response geometry, despite reduced individual neuron responses.

Perirhinal Cortex Learns A Predictive Map of The Task Environment

The paper identifies neural signatures of a predictive map in perirhinal cortex during task learning in mice using tactile working memory tasks.

The geometry of cortical representations of touch in rodents

The paper examines the geometric structure of neural representations in the somatosensory cortex of mice during touch tasks, revealing non-linear integration of sensory inputs and disentangled variables in orthogonal subspaces.

Corticotropin-releasing hormone signaling from prefrontal cortex to lateral septum supports social novelty preference

The paper identifies CRH-expressing inhibitory neurons in the prefrontal cortex that project to the lateral septum, showing their role in suppressing interactions with familiar mice and supporting social novelty preference.

The sensorimotor strategies and neuronal representations of tactile shape discrimination in mice

This study investigates how mice discriminate tactile shapes by analyzing neuronal activity in the barrel cortex during a shape discrimination task.

Scaling of information in large neural populations reveals signatures of information-limiting correlations

The paper investigates how information about visual stimuli is distributed across large neuronal populations in mouse V1, finding sublinear scaling due to correlated noise.

Naturalistic coding of working memory in primate prefrontal cortex

This study shows that primate lateral prefrontal cortex encodes working memory representations during naturalistic behavior and that ketamine disrupts this encoding by altering neuronal firing patterns.

Identifying the most influential features of neural population responses for information encoding and behavior

The paper identifies two key features of neural population responses that influence information encoding and behavioral performance.
