The Amygdala Regulates Social Motivation for Selective Vocal Imitation in Zebra Finches June 11, 2025
Imitation plays a key role in the acquisition of speech and cultural behaviors. Studies suggest that social interaction facilitates imitative learning, indicating that neural circuits involved in social behaviors can also influence the process of imitation. Vocal imitation in juvenile songbirds serves as a valuable model to investigate this idea. Here, we explore the mechanisms […]

Functional and Regional Specificity of Noradrenergic Signaling for Encoding and Retrieval of Associative Recognition Memory in the Rat June 11, 2025
Recognition of a familiar object in a novel location requires retrieval of the former object–place association and encoding of novel information. Such object-in-place (OiP) memory recruits a neural network including the hippocampus (HPC), medial prefrontal cortex (mPFC), and nucleus reuniens of the thalamus (NRe); however, the underlying cellular mechanisms are not understood. Locus ceruleus (LC) […]

Specializations in Amygdalar and Hippocampal Innervation of the Primate Nucleus Accumbens Shell June 11, 2025
The nucleus accumbens (NAc) is critical to goal-directed behaviors as the main input structure for limbic pathways to the basal ganglia. The NAc shell is composed of inhibitory projection neurons that receive robust glutamatergic innervation from both the hippocampus and amygdala. In view of primate-specific changes in the neural composition of the NAc, it is […]

CXCL12 Engages Cortical Inhibitory Neurons to Enhance Dendritic Spine Plasticity and Structured Network Activity June 11, 2025
The chemokine CXCL12 is a highly conserved peptide that regulates homeostatic processes in the brain throughout life. Recent work shows that CXCL12 increases dendritic spine density in cortical neurons, which requires activation of CXCL12's receptor CXCR4. This same pathway reverses cortical dendritic spine deficits and cognitive impairment in an animal model of neuroHIV. However, it […]

Atypical Cadherin FAT2 Is Required for Synaptic Integrity and Motor Behaviors June 11, 2025
In humans, mutations or deletions of atypical FAT cadherin genes are linked to autism spectrum disorder and cerebellar ataxia. However, their large genomic size and the enormous size of their encoded proteins have hampered functional studies, leaving the roles of FAT cadherins poorly understood. To address this gap, we investigated FAT2—an atypical cadherin selectively expressed […]

Zooming In and Out: Selective Attention Modulates Color Signals in Early Visual Cortex for Narrow and Broad Ranges of Task-Relevant Features June 11, 2025
Research on feature-based attention has shown that selecting a specific visual feature (e.g., the color red) results in enhanced processing in early visual cortex, providing the neural basis for the efficient identification of relevant features in many everyday tasks. However, many situations require the selection of entire feature ranges instead of just a single feature […]
