- Encephalization quotient (EQ), or encephalization level is a measure of relative brain size defined as the ratio between actual brain mass and predicted brain mass for an animal of a given size, which is hypothesized to be a rough estimate of the intelligence or cognition of the animal.hus, the same amount of brain matter can govern breathing in a large or a small body. While not all control functions are independent of body size, some are, and hence large animals need comparatively less brain than small animals.

What Albert Enstien contributed toMathematics. What Albert Enstien contributed to Mathematics. Albert Einstein's contribution to mathematics is his famous E=mc2. This is one of his most well-known accomplishments. One of Einstein's great insights was to realize that matter and energy are really different forms of the same thing.

- The most significant features that make humans unique in all of nature are our high intelligence and large brains. Here large means the brain is large relative to body size. Encephalization, or the relative size of the brain, is analyzed using a measure known as the encephalization quotient.

- Cephalization means that the animal has a defined head region in which there is a lot of nervous tissue (such as the brain in humans).Sponges are not cephalized because t … hey do not have defined head region nor do they have a central location for their nervous system.ephalization is the process in animals by which nervous and sensory tissues become concentrated in the head.. The evolution of a head allows scientists to distinguish betwee … n the head end, or anterior end, and the opposite end, the posterior.

- The above equation is an example of scaling, as it defines a relationship between a dependent variable (in the above, BM(e) or expected brain mass) and a measure of body size or scale.Further, the mathematical relationship above is non-.Returning to the topic of encephalization, once an estimate of brain mass is obtained using a credible statistical model (based on data from a range of species), encephalization can be measured.Foley and Lee [1991] provide a good explanation of encephalization quotients.urther, the mathematical relationship above is non-. Returning to the topic of encephalization, once an estimate of brain mass is obtained using a credible statistical model (based on data from a range of species), encephalization can be measured.

Fertilization The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg. One of these causes a change in the egg membrane(s), so that the attachment of and penetration by more than one spermatozoon cannot occur.

Encephalization The Encephalization Quotient (EQ) is the ratio of C over the expected value for C of an animal of given weight S.ere E is the weight of the brain, C is the cephalization factor and S is body weight and r is the exponential constant. The exponential constant for primates is 0.28 and either 0.56 or 0.66 for mammals in general.

Disorders of Cortical Formation: MR Imaging Features Axial T2-weighted MRI demonstrates a small open-lip schizencephaly. The septum pellucidum is absent. Schizencephaly is a rare, congenital cortical malformation characterized by abnormal slits, or clefts, in the cerebral hemispheres of the brain.he anomaly may be of the open-lip or closed-lip type. Closed-lip schizencephaly is characterized by grey matter-lined lips, which are in contact with each other. Open-lip schizencephaly has separated lips and a cleft of CSF extending to underlying ventricles.

Fertilization Fertilization in advanced plants is preceded by pollination, during which pollen is transferred to, and establishes contact with, the female gamete or macrospore. Fusion in advanced animals is usually followed by penetration of the egg by a single spermatozoon. The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg. One of these causes a change in the egg membrane(s), so that the attachment of and penetration by more than one spermatozoon cannot occur.

David Hawkins: The scales of enlightenment Occasionally, David Hawkins transcends his reliance on pseudo-scientific authority and seems to speak from a greater knowledge such as in this quote: There is ultimately, neither duality nor nonduality; there's only awareness.e references Karl Pribram as having shown the brain acts holographically, while, in truth, Pribram's is one of several theories. Hawkins makes vague references to nonlinear dynamics, chaos theory, and attractor patterns in support of his theory of consciousness.

- Psychologists have attempted to measure it for well over a century. Intelligence Quotient (IQ) is the score you get on an intelligence test. Originally, it was a quotient (a ratio): IQ= MA/CA x 100 [MA is mental age, CA is chronological age].Today, scores are calibrated against norms of actual population scores.ntelligence is a person's capacity to (1) acquire knowledge (i.e. learn and understand), (2) apply knowledge (solve problems), and (3) engage in abstract reasoning. It is the power of one's intellect, and as such is clearly a very important aspect of one's overall well-being.

SHH gene Sonic Hedgehog is necessary for the development of the front part of the brain (forebrain). This signaling protein helps establish the line that separates the right and left sides of the forebrain (the midline). Specifically, Sonic Hedgehog establishes the midline for the underside (ventral surface) of the forebrain.

- Binet devised a series of tests for each year of child development to calculate children's mental ages compared to their chrono-logical ages. He multiplied the final score by 100 to arrive at what is called the intelligence quotient..lthough all IQ tests require children to solve various problems, some tests result in only one total score while others provide three, five, or seven subscores. J. P. Guilford 1 assumed there were 180 separate kinds of intelligence, and believed there was no total or general intelligence score.

What is Cephalization? Cephalization refers to an evolutionary trend by which the neurons of an organism are concentrated towards one end of the body.The neurons become concentrated in the head region and allows the brain of the organism to be situated in one place.Cephalization is beneficial because it allows a complex brain to be developed. Together with the bilateral body plan, a complex brain enables an organism to make complex and quick movements.he neurons become concentrated in the head region and allows the brain of the organism to be situated in one place. Cephalization is beneficial because it allows a complex brain to be developed.
