The Effects of Age and Ability on Cortical Activation During Visual Processing

Year: 2006
Type: article
Abstract: It is well known that the aging process is accompanied by many changes including loss of cortical tissue and reduction in functional asymmetry.In recent years, the affects of ability on cortical activation for memory tasks has been investigated.As a replication and extension of Park et al. (2004), the present study examines the impact of age and ability on cortical activation during visual processing.fMRI was used to determine cortical regions that were significantly activated as the subjects viewed faces, pseudowords, houses, and chairs.Results revealed consistent activation of prefrontal regions by the superior subjects for all stimuli, with the exception of chairs for old superior visual processors.Additionally, the old average visual processor had significant activation of the fusiform gyrus for all stimuli.Results are discussed in terms of the dedifferentiation and compensation view as well as implications for future research regarding the impact of ability on cortical activation.i. ii.ACKOWLEDGEMENTS I would first like to acknowledge Dr. Neils-Strunjas for her help and support throughout this entire process.As my committee chair, your input has been invaluable.I really appreciated having the opportunity to continually share ideas regarding this research and thank you for allowing me to have a part in a project that is of particular importance to you.I would also like to acknowledge Martine Lamy.Without your help this project simply would not have been finished.Thank you so much for the hours you invested in the entire fMRI and data analysis process.Also, thank you Dr. Kelchner
