 \, Post-Doctoral Researcher\, Ä¢¹½¶ÌÊÓƵ\n\nAbstract: In early deve
 lopment\, the brain is highly sensitive to sensory inputs within a critica
 l period. Plasticity persists beyond this\, aiding learning and repair. I 
 investigated visual plasticity using fMRI with fluoxetine administration (
 a selective serotonin reuptake inhibitor – SSRI)\, in adult primates\, rev
 ealing neural changes during top-down behavioral manipulations. In a first
  part\, involving three distinct visual tasks coupling both top-down and b
 ottom-up mechanisms\, I will describe the effect of fluoxetine administrat
 ion on visual and attentional features. Then\, I will characterize these e
 ffects on the whole brain functional connectivity (fMRI) changes following
  an extensive reward-based learning of novel spatial contingencies\, befor
 e and after the impact of fluoxetine. The general decorrelation between th
 e ventral and dorsal visual pathways\, observed following reward-based per
 ceptual learning\, is further enhanced in the presence of the SSRI. Finall
 y\, I will show that while activations patterns in visual area V2 track th
 e spatial priority map constructed through the reward-based learning\, the
 se effects are greatly enhanced by fluoxetine.\n\n\nThe Feindel Brain and 
 Mind Seminar Series will advance the vision of Dr. William Feindel (1918–2
 014)\, Former Director of the Neuro (1972–1984)\, to constantly bridge the
  clinical and research realms. The talks will highlight the latest advance
 s and discoveries in neuropsychology\, cognitive neuroscience\, and neuroi
 maging.\n\nSpeakers will include scientists from across The Neuro\, as wel
 l as colleagues and collaborators locally and from around the world. The s
 eries is intended to provide a virtual forum for scientists and trainees t
 o continue to foster interdisciplinary exchanges on the mechanisms\, diagn
 osis and treatment of brain and cognitive disorders.\n\n \n
