A multi-unit microelectrode recording was performed in the somatosensory cortex SI and its receptive field was defined by light mechanical stimulation to the oral structures such as gingiva, periodontal tissues, palate, tongue and lip of the cat. The oral projection area was found somatotopically at the circumscribed area (about 3×3mm<SUP>2</SUP>) in the anterior coronal gyrus and situated more rostrally than the so-called face area. It was found that the area was subdivided into small loci which were characterized by projection from a particular part of the oral structures. The loci examined were represented in order of contralateral lip, contralateral, medial and ipsilateral part of gingiva and periodontal tissues, palate and tongue, in a caudal-rostral direction. Details of the geometric arrangement were as follows; they were distinguished functionally in two parts of the caudal site (contralateral) and the rostral site (ipsilateral) by mid-line (X) and also divided into the medial site (mandibular) and lateral site (maxillary) with an approximate parallel line (Y) to the coronal sulcus. The intersecting angle (φ) between the coronal sulcus and line X/ and the crossangle (θ) between line X and line Y were measured as an index of the representing distortion. Distance (Z) was also measured from the intersecting point of line X and the coronal sulcus to the cross point of the extended line of the cruciate sulcus and the coronal sulcus. The mean values of 10 adult cats were ø=99±24.6°, θ=105±18.6° and Z=4.3±1.4mm. The area mentioned above was also studied cytoarchitectonically in 5 cats. It was confirmed that localization of the loci was defined in area 3b.
