This paper presents a novel monkey model with impaired DISC1 gene to study adolescent prodromal phenotypes of psychiatric disorders, finding altered social behavior and disrupted brain connectivity.

This study combines rsfMRI and immunohistochemistry to show how whole-brain functional connectivity and EGR1 expression change during operant learning in mice.

This paper develops a method to activate specific neurons in the mammalian brain using peripheral administration of ligand precursors, demonstrating its effectiveness in inducing neurotransmitter release and behavioral responses.

This paper develops a novel micro-ECoG device and surgical technique to record multisensory neural activity from the parietal to temporal cortices in mice.

This study shows that silencing newborn neurons in the dentate gyrus disrupts the excitation/inhibition balance in the dorsal hippocampus, impairing cognitive flexibility in mice.

This study shows that activating locus coeruleus norepinephrine neurons enhances aversive memory retrieval in mice.

The paper presents a 3D digital brain atlas of the common marmoset monkey with MRI and Nissl histology data, offering improved segmentation and file format for neuroscience research.
