Paracentral minilobe

Lobulus paracentralis

Akinetic mutism

Located on the inside of the hemisphere in front of the central furrow. The minilobe is counted as the upper frontal lobe winding. Parts of the supplemental motor cortex (SMC) are localized to the paracentral minilobe.

Strokes affecting the paracentral minilobe can give rise to akinetic mutism. This condition means that the operation to communicate with the environment is impaired or has ceased. The sick person lies "staring at the ceiling", uninterested in his surroundings and without his own attempts to make contact. The power to act, the executive capacity, is impaired or gone. Their own initiative has disappeared apart from such basic, more or less reflexive, activities such as eating, going to the toilet and the like.
