| prefrontal area | Cortex of the frontal lobe of the cerebral hemisphere, originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann's areas 4 and 6), the dysgranular cortex (area 8), and the granular frontal (prefrontal) cortex anterior to the latter, now more often refers to the granular frontal (prefrontal) cortex. Synonym: frontal area. (05 Mar 2000) |
|---|---|
| premotor area | A somewhat ill-defined term usually referring to the agranular cortex of Brodmann's area 6. Synonym: premotor area. (05 Mar 2000) |
| preoptic area | Region of hypothalamus between the anterior commissure and optic chiasm. (12 Dec 1998) |
| prestriate area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| pretectal area | A narrow, transversally oriented rostral zone of the mesencephalic tectum, bounded caudally by the superior colliculus, rostrally by the habenular trigone, and laterally by the pulvinar thalami; the area contains several nuclei that receive fibres from the optic tract; it has bilateral efferent connections with the Edinger-Westphal nucleus of the oculomotor nuclear complex by way of which it mediates the pupillary light reflex. Synonym: pretectal region, pretectum. (05 Mar 2000) |
| primary visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| problem area wetland | <ecology> A wetland that is difficult to identify because it may lack indicators of wetland hydrology and/or hydric soils, or its dominant plant species are more common of nonwetlands. (09 Oct 1997) |
| secondary aortic area | Region of the chest at the mid-left sternal bases where aortic diastolic murmurs are often best heard. (05 Mar 2000) |
| secondary visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| pulmonary area | The region of the chest at the second left intercostal space, where sounds produced at the pulmonary valve of the right ventricle are heard most distinctly. (05 Mar 2000) |
| Selected Area Electron Diffraction | <technique> In this diffraction mode an aperture is used to define the area from which a diffraction pattern is to be recorded from a thin sample. This aperture is typically located in an image plane below the sample. Selected Area Electron Diffraction patterns are simple spot patterns and are of use in phase determination (lattice spacing measurement) and defect analysis (sample orientation). Acronym: SAED (05 Aug 1998) |
| sensorimotor area | The precentral and postcentral gyri of the cerebral cortex. (05 Mar 2000) |
| septal area | The region of the cerebral hemisphere that stretches as a thin sheet of brain tissue between the fornix bundle and the ventral surface of the corpus callosum, forming the medial wall of the lateral ventricle's frontal horn; it extends ventrally through the narrow interval between the anterior commissure and the rostrum of corpus collosum as the precommissural septum or subcallosal gyrus, which is continuous caudally with the preoptic area and hypothalamus, as well as more laterally with the innominate substance; its major functional connections are with the hippocampus and hypothalamus. (05 Mar 2000) |
| silent area | Any area of the cerebrum or cerebellum in which lesions cause no definite sensory or motor symptoms. (05 Mar 2000) |
| hypothalamic area, anterior | Loose heterogeneous collection of cells in the anterior hypothalamus, continuous rostrally with the medial and lateral preoptic areas and caudally with the tuber cinereum. (12 Dec 1998) |
