Habenular Nuclei

A small pair of nuclei located in the epithalamus, part of the limbic system, involved in reward processing, aversion, and regulating dopamine and serotonin systems.

Key Functions:

• Involved in processing negative reward and aversion.
• Regulates dopamine and serotonin release, influencing mood.
• Plays a role in decision-making and addiction.

Interacting Systems & Components:

• Epithalamus (located within)
• Limbic System (part of)
• Ventral Tegmental Area (VTA) (inhibits dopamine neurons)
• Raphe Nuclei (interacts with for serotonin regulation)
• Reward System (modulates negative aspects)
