Neural Correlates Of Enhanced Attentional Filtering Of Distractors Across Vs. Within Visual Hemifields In The Lateral Prefrontal Cortex, Maryam Nouri Kadijani

Electronic Thesis and Dissertation Repository

Attention allows us to focus on only important sensory stimuli in a world full of distractors. However, the ability to allocate attention to important targets becomes more difficult when the distractors are located within the same as compared to when they are in the opposite visual hemifield. The neural mechanisms underlying this effect remains unclear. We recorded neuronal responses in lateral prefrontal cortex (LPFC), an area involved in the generation of signals related to attention, of two macaque monkeys while they performed a covert spatial attention task in two different conditions. Two stimuli were either separate in the left and …
