Understanding how the laminar architecture of the posterior parietal cortex supports visual behaviour

Amidst a barrage of visual stimuli, spatial attention is a cognitive process that enables the selective focus and efficient processing of behaviourally relevant stimuli. Brain areas are intricately connected together in networks, to orchestrate such processes. Within a given area, neurons are organised into layers, receiving various connections from other brain areas and shaping information flow within a network. My work reveals how spatial attention differentially influences activity in these layers, within the posterior parietal cortex - a pivotal region in the visual attentional network. These insights lay the foundation for untangling how connections between brain areas support cognition.
