(n.) The point of junction of the coronal and sagittal sutures of the skull.
Example Sentences:
(1) The proprioceptive zone occupied a territory extending from 1.0 to 2.5 mm caudal to the bregma and from 2.0 to 3.0 mm lateral from the midline.
(2) Sutures fused too early in life for lambda and bregma to be useful as landmarks in adult ferrets.
(3) Tracks of the ST are localized most often on and round the sagittal suture, bregma and lambda.
(4) A roentgenographic survey of the skeletal system showed a sutural hyperostosis of the skull at bregma and a hypoplastic cervical vertebra.
(5) Topographical maps were constructed with respect to Bregma and midline reference points.
(6) It is also suggested that this point be used directly as the zero point of reading the coordinates instead of the bregma.
(7) Bregma (BR) is moving anteriorly in BCC, inducing an anterior movement of the calvaria with a bulge around BR.
(8) ICMS rostral to bregma, within cortical band along sagittal suture (area 6) evoked mostly ipsilateral MRs of vibrissae and upper lip, more often from the left hemisphere.
(9) These coordinates may be referenced by earbar-zero or bregma.
(10) Continuous CSF samples were collected directly from the third anterior ventricle with an indwelling cannula inserted through the bregma point, and drug concentrations were determined by high-pressure liquid chromatography and radioimmunoassay micromethods.
(11) The highest density of labelled cells in the medial amygdala occurred 2.30 to 2.80 mm caudal to bregma.
(12) The craniocerebral landmarks--the coronal suture and bregma--and the central anatomy in the CT and the MRI favors their localization.
(13) That point on the corpus callosum is characterized using simple planar geometry in relation to three anatomic landmarks in that same plane: the glabella, the inion, and the bregma (midline intersection of the coronal suture).
(14) In comparison with the average figure, the proportion of the retrogradely labelled parvalbumin-containing neurons was higher in the middle part (around 1.5 mm anterior to the bregma) than in either the rostral or caudal ends.
(15) At different rostrocaudal levels, the proportion of parvalbumin- and choline acetyltransferase-positive neurons varied in a consistent manner, and the largest number of parvalbumin-containing neurons was found at the level 1.9 mm anterior to the bregma.
(16) If rats of different weights are used, greater accuracy can be achieved if bregma is used as the reference point for work with rostral structures and the interaural line for work with caudal structures.
(17) They concern the parietal bones and may extend from the bregma till to the lamda or occupy only a part of this distance.
(18) Intravital determination of a point on the surface of the scull with horizontal coordinates of the anterior commissure is suggested for selection of young rabbits with a normal location of brain structures in regard to the zero point (bregma ) as well as for introduction of corrections in the location of the zero points.
(19) A variety of other telencephalic regions anterior and posterior of bregma exhibited modest to weak intensity of labelled MR mRNA.
(20) The effective lesions included parts of the cortex both dorsal and ventral to the rhinal sulcus and extended from approximately 1.8 to 3.8 mm posterior to bregma.
Regma
Definition:
(n.) A kind of dry fruit, consisting of three or more cells, each which at length breaks open at the inner angle.
