PSYC33H3 Chapter Notes -Acquired Brain Injury, Extrastriate Cortex, Middle Frontal Gyrus
Document Summary
Training of goal-directed attention regulation enhances control over neural processing for individuals with brain injury. Deficits in attention/executive control are common delibating/persistent consequences of brain injuries. Objective: identify the neural mechanisms that underlie cognitive improvements w/rehab training of attention regulation. Hypothesis: intensive training in attention regulation improves cog processing via enhancement of modulatory control of neural processing in pts with acquired brain injury. 12 pp either in standardized training design to target goal-directed attention regulation in comparison to brief education (control cond). Training resulted in sig improvement on behavioral measures of attention/executive control. Mean demographics: 48 years, all had ongoing cognitive dysfunction, difficulties in personal life functioning consistent with executive deficits, all on stable med regimens. Brain injuries include stroke, trauma, haemorrhage, tumor resection and chemotherapy affecting both frontal/cortical white matter regions. Fmri adapted for testing the effects of intervention for pts wit varied pathology were used to index modulatory control of neural processing.
