 | | This region, together with the anterior parts of the cingulate gyrus (limbic system) and septum is also concerned with emotional balance and the emotional modulation of behaviour. | | | The lower extremities of the body are represented on the medial cortical surface, on the anterior part of the paracentral lobule. | | | There is partial flaccidity (hypotonic) due to spinal shock, but the affected part becomes rapidly hypertonic (spastic) due to lack of cortical inhibition of the reticulo-spinal system. |

| | The cortex of the angular gyrus is important because it is involved in relating visual impressions to stereognostic impressions (appreciation of the nature of objects by means of touch). | | | The superior temporal gyrus is continued without interruption into the transverse temporal gyrus, these areas of cortex being regions for receiving and processing auditory sensations. | | | On the left side of the brain (in most individuals), the opercular and triangular parts of the inferior frontal gyrus are referred to as Broca's area, which is associated with motor elements of speech. |

The inferior parietal lobule is divided into the "supramarginal gyrus," the "angular gyrus," and an additional posterior convolution. |

| | Functional magnetic resonance imaging of odor identification: the effect of aging. |
| | RESULTS: The group mapping of young subjects showed extensive activation in the orbitofrontal cortex, commonly believed to be the olfactory cortex, some limbic areas (the hippocampus and the thalamus), regions involved with gustatory sensation (the anterior insula and the inferior postcentral gyrus), superior and inferior temporal gyri, and cerebellum. | | | METHODS: We gave three mainly olfactory-mediated odors (limonene, methylsalicylate, and eugenol) to six young and six elderly subjects and observed the areas activated by using blood oxygen level dependent contrast functional magnetic resonance imaging. | | | In the elderly group, only the left inferior temporal gyrus and the primary visual cortex reached accepted significance levels. |
