Oct 27, 2025 · Several central sulcus localizing signs are specific to MRI signal characteristics: In cases where anatomy is uncertain, or it is of critical importance to confirm the anatomy, then functional MRI …

The presence of perirolandic signal changes would reflect neuronal death following acute energy failure in a metabolically demanding region (primary motor and sensory cortex) within the dominant …

In neuroanatomy, the central sulcus (also central fissure, fissure of Rolando, or Rolandic fissure, after Luigi Rolando) is a sulcus, or groove, in the cerebral cortex in the brains of vertebrates.

The present study was therefore undertaken to evaluate by high-resolution fMRI the activity pattern of the perirolandic region (including pre- and postcentral gyri) during execution and imagery of a …

Download scientific diagram | (A) Diagram of the perirolandic region illustrating the primary motor cortex, primary somatosensory cortex, and the classic homunculus.

Imaging Findings: Diffusion and ADC images reveal gyriform areas of diffusion restriction in the left cerebral cortex, including the visual cortex, and sparing of the perirolandic cortex [1].

May 7, 2020 · The presence of perirolandic signal changes would reflect neuronal death following acute energy failure in a metabolically demanding region (primary motor and sensory cortex) within the …

Oct 26, 2020 · The perirolandic region, also known as central lobe (1) or paracentral area (6), is one of the most eloquent areas of the brain, which consists of pre- and postcentral gyrus, central sulcus, …

Purpose: To evaluate the signal intensity (SI) characteristics of the perirolandic cortex (PRC) in the neurologically normal population on turbo fluid-attenuated inversion-recovery (FLAIR) magnetic …

The perirolandic cortex (PRC) shows lower signal intensity (SI) than the superior frontal cortex (SFC) in MR imaging. Study evaluated 112 neurologically normal patients to characterize PRC SI on turbo …
