Arginine Vasopressin, Synaptic Plasticity, and Brain Networks

Area of Science:

• Neuroscience
• Neuroendocrinology
• Molecular Biology

Background:

• Arginine vasopressin (AVP) is a neurohypophysial hormone synthesized in the central nervous system.
• AVP functions as a neurotransmitter/neuromodulator, primarily acting via vasopressin receptors A and B.
• AVP plays a role in regulating social behaviors, cognition, and autonomic functions.

Approach:

• This review synthesizes current research on AVP's molecular mechanisms.
• It examines AVP's impact on synaptic plasticity, a key process for learning and memory.
• The review also explores AVP's effects on brain activity at both synaptic and network levels.

Key Points:

• AVP significantly modulates synaptic plasticity through various molecular pathways.
• AVP influences event-related potentials and blood oxygen level-dependent (BOLD) responses in specific brain regions.
• AVP affects network-level oscillatory activity, impacting overall brain function.

Conclusions:

• AVP exerts widespread modulatory effects across different levels of brain organization.
• Understanding AVP's mechanisms is crucial for comprehending its role in complex behaviors and brain function.
• This review provides a comprehensive overview of AVP's impact on the brain, from molecular to network scales.
