Research Proposal: Investigating Cortical Homunculus Dysfunction and Pain Sensitivity Mapping in ME/CFS and Post-COVID Conditions

  1. Background and Rationale The cortical homunculus represents the somatotopic organization of the human body within the primary motor and sensory cortices. This organization reflects the unequal distribution of neural resources, with highly sensitive or finely controlled body regions (e.g., hands, lips, face) occupying disproportionately large cortical areas. Originally described by Wilder Penfield and Edwin Boldrey , this model remains central to understanding how the brain processes sensory input and motor output. ME/CFS and post-COVID conditions frequently involve neurological symptoms such as localized pain, hypersensitivity (hyperalgesia or allodynia), and muscle weakness. While current research focuses on neuroinflammation and autonomic dysfunction, the potential role of somatotopic cortical disruption—particularly involving pain sensitivity—remains insufficiently explored. Given the close functional relationship between the sensory homunculus and the supplementary mot...

Can Happiness Become a Disorder? Understanding Mania, Excitement, and Bipolar Disorder

By
Happiness is typically viewed as one of the most desirable human experiences—something we strive for, cultivate, and protect. But an important and less commonly discussed question is this: In psychiatry, the answer is yes—but not in the way we usually think of happiness. What appears on the surface as extreme joy is often something more complex and potentially dangerous: mania , a core feature of bipolar disorder . Possible Causes of Mania and Bipolar Disorder The exact cause of mania is not fully understood, but current neuroscience suggests it arises from a combination of biological, genetic, and environmental factors . One major contributor is dopamine system dysregulation , in which brain circuits involved in reward, motivation, and anticipation become overactive, particularly along pathways connecting the ventral tegmental area, nucleus accumbens, and prefrontal cortex.  Genetic predisposition also plays a significant role, with bipolar disorder often running in families....
