== Color-number association ==
In this study, a set of monozygotic twins were performing various tests to display their color-number association. This synesthetic association is shown by R and T, the twins, as naming certain letters as colors. Each specific letter had a different color scheme which had been highly consistent over the past 6 years. At the time of the testing, the twins were 12 years and 2 months old.

== Test Administered ==
The twins were given a test which produces an effect known as the Stroop Effect. They were asked to name the color of the displayed digit on their screen as soon as it appeared. The Stroop Effect interfered with their reaction time of naming the correct color of the digit when the image appeared.

== Results ==
It was shown that the twins had a longer reaction time when the colors of the shown digit did not match their personal color-association of choice. This additional reaction time results from the twins photism, or production of a sensation of light or color to another sense organ. The term given for this such condition is called Associator Synesthesia. The researchers believe the twins' childhood jigsaw puzzle is the origin of their color-number association.

<STRONG><H2>Inferior Parietal Lobe:</H2></STRONG>
<STRONG><H3>
== Position in Brain ==
</H3></STRONG>
The inferior Parietal Lobe resides beneath the horizontal space of the intraparietal sulcus. This area is at the posterior of the parietal lobe. Within the inferior parietal lobe are the angular and supramarginal gyri.
<STRONG><H3>
== Uses ==
</H3></STRONG>
Helps with the multiple aspects of sensory processing and sensorimotor integration
One of the main uses of the inferior parietal lobe is signaling the spatial location of objects. It also helps with the position of the viewers head and eyes when focusing on an object.

== Associated Syndromes ==
Damage or lesion to the parietal lobe area can result in syndromes such as Balint's Syndrome, Gerstmann's Syndrome, and hemineglect.

Hemineglect

<STRONG><H1>Hemineglect:</H1></STRONG><BR>
<STRONG><H2>Cause</H2></STRONG><BR>
Hemineglect is a behavioral syndrome in which there has been damage to the parietal lobe. It is also commonly referred to as hemispatial neglect or spatial neglect. The amount of dysfunction shown is dependent on the extent of damage to the parietal lobe. The damage to the parietal lobe is caused most often by a stroke.

Although the damage can happen to either the left or right side, the effects are far greater when the left side of the individual is damaged (indicating right parietal lobe damage). The effects of the right parietal lobe are greater due to the fact is governs the control over the left parietal lobe and itself. Left side parietal damage forms a more manageable version of Hemineglect, due to the fact the right parietal lobe will still be able to govern over both sides.<BR>
<STRONG><H2>Symptoms</H2></STRONG><BR>
Someone with Hemineglect is not able to pay any attention to half of their visual field. However there are reported cases of Hemineglect which individuals have different spatial referents such as left/right foreground or distance.
Cases range from individuals not caring about the Â½ of the visual field missing, to the extreme of the absolute denial of Â½ of their own body.<BR>
<STRONG><H2>Examples</H2></STRONG><BR>
When an individual with hemineglect is drawing a clock, half of the clock will be very dysfunctional if apparent at all. See the attached picture for an example.
Although it seems as though these individuals are impaired, the non-damaged side is working just as any other normal person. It is the damaged side which is causing the problems.<BR>

<STRONG><H2>Alexander Luria:</H2></STRONG>
<STRONG><H3>
== Background ==
</H3></STRONG><BR>
Alexander Luria, born in a city east of Moscow named Kazan, attended Kazan State University (graduated in 1921) and the 1st Moscow Medical Institute (graduated in 1937). He later become a professor and received two more degrees by the year of 1943. During these years, Alexander helped to assemble the Faculty of Psychology at the Moscow State University where he was later named head of both the pathopsychology and neuropsychology studies.<BR>
<STRONG><H3>
== Accomplishments ==
</H3></STRONG><BR>
Through constant communication with Sigmund Freud and worke with reaction times and thought processes, Luria helped to develop the first lie detector machine in 1932.<BR>

Luria also traveled to Central Asia during the years of the 1930's where he studied the psychological changes of memory, perception and problem solving in relation to the educational development in of an undereducated people. Working heavily with language, Luria focused on the topic of aphasia (The loss of the ability to understand speech or produce it).<BR>

During World War II, Luria worked with a team of doctors in an army hospital treating wounded patients with brain lesions. The end result of these actions is the development of the area now formally known as neuropsychology.<BR>

<H3><STRONG>
== Tests Created by Alexander ==
</STRONG></H3>
The Luria-Nebraska test is one based on the scales of neuropsychological functioning. This test is designed for patients 15 years of age and older, but it can be administered to children as young as 12 years of age.

<H1><STRONG>Computed Tomography:</STRONG></H1><BR>
<H2><STRONG>When</STRONG></H2><BR>
The very first step of the long process which scientists have taken to arrive at a CT scan starts with Alessandro Vallebona in 1930. He suggested taking a single slice of the body on radiographic film, which is known as tomography. The original prototype of a CT scanner was developed in 1971 and the first brain scan was performed in England at the Atkinson Morley Hospital in 1972.<BR>
<H2><STRONG>How</STRONG></H2><BR>
The CT scan is an important tool used to supplement the use of x-rays and ultrasounds. It is used to create detailed images of the inside of an individual's body including their chest, abdomen, head, and other various parts of the body. These images can then be displayed on a computer using 3-d rendering techniques.
<BR>

<H2><STRONG>Use</STRONG></H2><BR>
This is a medical method used to scan the inside of an object using a large series of two-dimensional x-rays taken around a single axis.
With the use of CT scans, doctors can determine a number of factors of a patient including brain activity, bone density and many others. One of the most important factors of using a CT scan involves looking for abnormalities in the brain such as unnatural growths or lesioned areas. <BR>
