Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated. Northern blot hybridization indicates that false ratio is high with the cDNA array experiment.

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.
