Loss of neuronal population organization links pathology to behavior in a model of Alzheimer's disease

This study links neuronal population organization disruption to behavioral changes in a macaque model of early-stage Alzheimer's disease and related dementias.

Progressive loss of independence in neuronal representations predicts cognitive decline

The paper shows that reduced independence in neuronal representations predicts cognitive decline in Alzheimer's disease models and humans.

Guided by Noise: Correlated Variability Channels Task-Relevant Information in Sensory Neurons

The paper shows that shared variability in sensory neurons aligns with task-relevant features and action plans, and that this alignment enhances behaviorally relevant information.

Orthogonal neural representations support perceptual judgements of natural stimuli

The paper shows that orthogonal neural representations in V4 allow stable perception of object position despite irrelevant background features in natural scenes.

Coordinated Response Modulations Enable Flexible Use of Visual Information

The paper shows that coordinated response modulations in V4 enable flexible behavior by reformatting visual information for downstream neurons, without changing coding within the sensory area.

Object representation in a gravitational reference frame

The paper identifies a neural strategy in the anterior inferotemporal cortex that maintains object orientation stability despite changes in head tilt and retinal image rotation.

Attention improves information flow between neuronal populations without changing the communication subspace

The paper shows that visual attention enhances information flow between visual and motor neurons without altering their shared communication subspace.
