Self-referential processing is defined as the process by which a person becomes aware that specific contents are related to his or her own self. Cortical midline structures (CMS), such as dorsal and medial prefrontal cortex, and regions such as inferior frontal cortex, insula, and temporal pole have been implicated in self-referential processing. However,(More)
We report the successful grafting of embryonic (newborn) rat retina into a lesion site (die-back zone) of an adult retina with a corresponding 90-100% survival rate. A penetrating lesion was made through the sclera, choroid and retina on the superior surface of the host eye and closed with microsutures. The lesion site was either allowed to stabilize for 5(More)
A lesion paradigm involving a small penetrating incision made through the sclera, choroid and retina of the adult rat eye creates a unique environment for the study of the damaged retina. More specifically, the dependable formation of a small focal retinal lesion makes this an ideal model for the determination of conditions that may stimulate retinal(More)
We have previously reported the successful transplantation of neonatal rat retina to the lesioned retinas of adult host rats. The current studies provide a much more in-depth evaluation of the optimal conditions under which successful grafting can be achieved. Utilizing the same surgical approach and techniques as in our earlier studies, the variables of(More)
A small penetrating incision made through the sclera, choroid and retina of the adult rat eye creates a unique lesion paradigm. More specifically, by one to two weeks after the incision the wound area stabilizes, leaving a clean inflammation-free degeneration gap or 'die-back zone' (200-300 microns wide) between the cut edges of the intact retina. The(More)
Considerable work has demonstrated that inferior frontal gyrus (IFG), anterior insula cortex (AIC) and the supplementary motor area (SMA) are responsive during inhibitory control tasks. However, there is disagreement as to whether this relates to response selection/ inhibition or attentional processing. The current study investigates this by using a(More)
The neural circuitry underlying response control is often studied using go/no-go tasks, in which participants are required to respond as fast as possible to go cues and withhold from responding to no-go stimuli. In the current task, response control was studied using a fully counterbalanced design in which blocks with a low frequency of no-go cues (75% go,(More)
