I do see a substantial decrease of the amount of corpus callosum fibers projecting towards the cortex as we age. Some fibers still project to the cortex although a lot of them project downwards instead. I don't know whether this is caused by aging or DTI artifacts such as the termination of line propagation because of the lower FA or the crossing fiber issue.<br><br>Jun Yi Wang<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><span><span><span><span><span><span><span style="background: transparent none repeat scroll 0% 0%; -moz-background-clip: border; -moz-background-origin: padding; -moz-background-inline-policy: continuous;">Postdoctoral

all,</span></font></p>
<p class="MsoNormal" dir="LTR" style="text-align: left; direction: ltr; unicode-bidi: embed;"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">We
are currently working on data from elderly stroke/TIA patients. </span></font></p>
<p class="MsoNormal" dir="LTR" style="text-align: left; direction: ltr; unicode-bidi: embed;"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">In
many of the TIA patients, who have good DTI data, for some reason the CC does
not built well, we can't see the fan. </span></font></p>
<p class="MsoNormal" dir="LTR" style="text-align: left; direction: ltr; unicode-bidi: embed;"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">This
is not due to incorrect directions (the CST is built OK).</span></font></p>
<p class="MsoNormal" dir="LTR" style="text-align: left; direction: ltr; unicode-bidi: embed;"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">ROI
measurements give reasonable values. We even changed the flip-angel for the
FACT, and got the same results.</span></font></p>
<p class="MsoNormal" dir="LTR" style="text-align: left; direction: ltr; unicode-bidi: embed;"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Any
suggestions? Is it a known phenomenon in elderly / stroke / TIA patients? </span></font></p>
