====== Medial frontal lobe ====== {{rss>https://pubmed.ncbi.nlm.nih.gov/rss/search/1nGQFE-05Nk05g_qVYjSmRzgMYc0s3B5VRI43O3V5ixLQ3Rg7t/?limit=15&utm_campaign=pubmed-2&fc=20250218074622}} The **medial [[frontal lobe]]** refers to the **inner (medial) portion of the frontal [[lobe]]**, located along the midline of the brain, above the [[corpus callosum]]. It plays a crucial role in **[[cognitive control]], [[decision-making]], emotional regulation, and [[social behavior]]**. ### **Key Structures in the Medial Frontal Lobe:** 1. **Anterior Cingulate Cortex (ACC):** - Involved in **cognitive control, emotion regulation, and pain processing**. - Dysfunction is associated with **depression, anxiety, and OCD**. 2. **Pre-supplementary Motor Area (pre-SMA) & [[Supplementary Motor Area]] (SMA):** - Important for **planning and initiating voluntary movements**. - Implicated in **motor disorders like Parkinson’s disease**. 3. **Medial Prefrontal Cortex (mPFC):** - Plays a role in **self-referential thinking, decision-making, and social cognition**. - Involved in **understanding the thoughts and emotions of others (theory of mind)**. 4. **Orbitofrontal Cortex (OFC) (partially medial):** - Regulates **reward-based decision-making and emotional responses**. - Dysfunction can lead to **impulsivity and poor judgment**. ### **Functions of the Medial Frontal Lobe:** - **Executive Function & Decision-Making:** - Helps in **goal-oriented behavior and adapting to new situations**. - **Emotion & Social Behavior:** - Plays a role in **empathy, morality, and understanding social norms**. - **Motor Control:** - Contributes to **voluntary movement planning and execution**. ===== Clinical Relevance ===== - Damage to the **medial frontal lobe** can result in: - **Apathy and lack of motivation (abulia)** - **Poor decision-making and impulse control** - **Deficits in emotional and social cognition (e.g., autism, schizophrenia)** - **Akinesia (difficulty initiating movement)** in disorders like **Parkinson’s disease**.
