This study investigated the viability of fetal neocortical block grafts transplanted into adult ischemic cortical lesions. Recipient rats sustained focal ischemic lesions by permanent occlusion of the middle cerebral artery 4-7 days prior to transplantation. Twenty days later, the animals were sacrificed and the brains examined using triphenyltetrazolium(More)
Sensorimotor cortical lesions in newborn rats lead to the formation of abnormal projections from the opposite intact sensorimotor cortex. In the present study the influence of fetal neocortical transplants on this lesion-induced plasticity was examined. Newborn rats received unilateral frontal neocortical lesions. One experimental group received grafts of(More)
Fetal neocortical transplants placed into frontal cortex aspiration lesion cavities in newborn rats have been shown to survive and exchange connections with the host brain. To further study the afferent innervation of such transplants, enzyme- and immunohistochemical techniques were employed to examine the distribution of cholinergic, catecholaminergic and(More)
Using anatomical and electrophysiological methods, previous studies from this laboratory demonstrated that fetal neocortical block transplants placed into the excitotoxically ablated cortex of adult rats can establish functional connections with the host central nervous system. In order to further examine functional integration at the level of genomic(More)
