What's the difference between cephalization and neural?
Cephalization
Definition:
(n.) Domination of the head in animal life as expressed in the physical structure; localization of important organs or parts in or near the head, in animal development.

(11) Conventional Roentgenographic Cephalometric Methods (RCM) have certain conceptual and geometric constraints that ensure that their descriptions of cephalic growth and comparisons of cephalic form are reference-frame-dependent; and it is impossible to determine which, if any, RCM reference frame provides a biologically more correct description or comparison.
(12) To better understand the mechanism of cerebral blood flow during CPR in humans, we determined the aortic-carotid artery pressure difference, the cephalic perfusion pressure (the carotid artery-jugular vein pressure difference), and thoracic inlet venous "valving" (the central venous-jugular vein pressure difference), while administering standard doses of epinephrine.

(17) The following clinical factors tend to be associated with an increased number of respirator brains: A. Cerebral trauma B. Subnormal body timperature C. Low systolic blood pressure D. Dilated pupils E. Pupils unresponsive to light F. Absence of cephalic reflexes G. Electrocerebral Silence (ECS) 6.
(18) On the contrary, the SEPs obtained with a cephalic reference on stimulating the posterior tibial nerves were of small amplitude and disorganized.
(19) The cephalic signal can be superseded by juvenile hormone, whose presence is necessary for each follicle to become vitellogenic.
(20) The cells contained spherical granules with variable densities and diameters ranging between 40 and 280 nm in the rostral (=cephalic) lobe, and between 60 and 260 nm in the caudal lobe.
Neural
Definition:
(a.) relating to the nerves or nervous system; taining to, situated in the region of, or on the side with, the neural, or cerebro-spinal, axis; -- opposed to hemal. As applied to vertebrates, neural is the same as dorsal; as applied to invertebrates it is usually the same as ventral. Cf. Hemal.
Example Sentences:
(1) By presenting the case history of a man who successively developed facial and trigeminal neural dysfunction after Mohs chemosurgery of a PCSCC, this paper documents histologically the occurrence of such neural invasion, and illustrates the utility of gadolinium-enhanced magnetic resonance scanning in patient management.
(2) Some common eye movement deficits, and concepts such as 'the neural integrator' and the 'velocity storage mechanism', for which anatomical substrates are still sought, are introduced.
(3) 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.
(4) This attack can take place during organogenesis, during early differentiation of neural anlagen after neural tube closure or during biochemical differentiation of the brain.
(5) This effect of adrenalectomy on MNE excitability was further demonstrated by recording directly the neostigmine-induced repetitive neural discharges responsible for the muscle fasciculations.
(6) It is also suggested that degenerative changes occur in the dentate gyrus and may be involved in the delayed neural death of CA1 pyramidal cells.

(8) Hence, the absence of NGF receptors on premigratory neural crest and early migratory neural crest cultures was not due to enzymatic alterations of the receptor.
(9) By 3 d in the chick embryo, the first neurons detected by antibodies to Ng-CAM are located in the ventral neural tube; these precursors of motor neurons emit well-stained fibers to the periphery.
