Anteroventral Thalamic Nucleus (Av) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Anteroventral Thalamic Nucleus (AV) is a key component of the Papez circuit and limbic system, playing essential roles in memory consolidation, spatial navigation, and emotional processing. It serves as a critical relay between the hippocampus and cortical structures. [1]

The AV contains specialized thalamocortical neurons:
The anterior thalamic nuclei form a complex including:
Key genes expressed in AV neurons include:
Deep brain stimulation targeting anterior thalamus for memory
Neurogenesis promotion in thalamic circuits
Gene therapy for trophic support
Biomarkers from anterior thalamic connectivity
Papez Circuit
Retrosplenial Cortex
