What's the difference between brain and encephalocele?
Brain
Definition:
(n.) The whitish mass of soft matter (the center of the nervous system, and the seat of consciousness and volition) which is inclosed in the cartilaginous or bony cranium of vertebrate animals. It is simply the anterior termination of the spinal cord, and is developed from three embryonic vesicles, whose cavities are connected with the central canal of the cord; the cavities of the vesicles become the central cavities, or ventricles, and the walls thicken unequally and become the three segments, the fore-, mid-, and hind-brain.
(n.) The anterior or cephalic ganglion in insects and other invertebrates.
(n.) The organ or seat of intellect; hence, the understanding.
(n.) The affections; fancy; imagination.
(v. t.) To dash out the brains of; to kill by beating out the brains. Hence, Fig.: To destroy; to put an end to; to defeat.
(v. t.) To conceive; to understand.

(15) Brain damage may be followed by a number of dynamic events including reactive synaptogenesis, rerouting of axons to unusual locations and altered axon retraction processes.
(16) Based on our results, we propose the following hypotheses for the neurochemical mechanisms of motion sickness: (1) the histaminergic neuron system is involved in the signs and symptoms of motion sickness, including vomiting; (2) the acetylcholinergic neuron system is involved in the processes of habituation to motion sickness, including neural store mechanisms; and (3) the catecholaminergic neuron system in the brain stem is not related to the development of motion sickness.
(17) The regional distribution of beta-adrenoceptor subtypes was found to be similar to that seen in the rat brain.
(18) We assessed changes in brain water content, as reflected by changes in tissue density, during the early recirculation period following severe forebrain ischemia.
(19) If tracer is introduced into the carotid artery after osmotic treatment, brain uptake is increased by a net factor of 50 (a factor of 70 due to elevation of PA, multiplied by 7 due to infusion by the carotid route) as compared to uptake by normal, untreated brain with infusion into a peripheral vein.
(20) This study examined both the effect of variations in optical fiber tip and in light wavelength on laser-induced hyperthermia in rat brain.
Encephalocele
Definition:
(n.) Hernia of the brain.
Example Sentences:
(1) Encephalocele is the most common cause of occipital midline extracranial mass associated with hydrocephalus.
(2) MRI showed an anterior basal encephalocele protruding into the nasal cavity.
(3) Necropsy findings revealed multiple congenital malformations with occipital meningo-encephalocele and agenesis of the cerebellum, 6 digits on the hands and feet, polycystic kidneys.
(4) This review is based on the sincipital encephaloceles with the other cephaloceles included for completeness.
(5) A congenital nasoglabellar mass is usually either a meningocele or an encephalocele.
(6) They consisted of four encephaloceles, six meningoceles, and five atretic cephaloceles.
(7) A rare case of sphenoethmoidal encephalocele with detailed pathological studies is reported.
(8) 1367 survivors (997 myelomeningoceles, 207 meningoceles, 81 lipomas of the cauda equina and 82 encephaloceles) were included in this study of sex differences.
(9) We describe a fetus with an asymmetric, nonmidline, parietal encephalocele that appeared to result from "expulsion" through the center of the membranous bone; the fetus also had laryngeal atresia, which caused pulmonary overdistension (fetal Valsalva maneuver) with consequent hydrops fetalis.
(10) The patient was admitted to our hospital 4 hours after birth because of parietal encephalocele.
(11) The triad of the syndrome consists of occipital encephalocele, polycystic kidneys and postaxial polydactyly.
(12) If the arachnoid is not intact, an encephalocele results which presents predominantly as a mass without a cerebrospinal fluid leak.
(13) The different types of cephalic axial dysraphic disorders presenting in arsenic-treated fetuses delivered at later gestational stages (predominantly exencephaly and encephaloceles) could all be traced back and related to one or the other of these early forms of disturbed neurulation.
(14) In case of other anomalies, the findings in the prenatal diagnosis and at autopsy were encephalocele, adrenal hypoplasia and a single umbilical artery.
(15) But, Hutchinson stated in his experience that first, a closure disorder of the neural tube caused encephalocele.
