Research Interest:

Mr. Doudlah is interested in understanding how our brain creates accurate representations of our three-dimensional (3D) world, and how that information is communicated to other systems that help us interact with our environment. To investigate how our visual system encodes 3D representations of our environment, he uses a combination of behavioral tasks and electrophysiology. He trains rhesus macaque monkeys to perform 3D surface orientation discrimination tasks to understand how viewing conditions effect
perception. In parallel, he records from brain regions associated with 3D vision to investigate the functional properties at the single cell and population level. He is interested in understanding how our brain encodes our environment and how these signals are transformed from sensory to motor signals, such as during eye movements. He is also interested in understanding brain connectivity at a systems level, to identify hubs of sensory integration and pathways underlying sensorimotor transformations. Currently, he is investigating the network within the dorsal visual stream (i.e., the ‘where’ pathway), which transforms 2D retinal images into 3D visual perception, to better understand how the areas that he is recording from are connected within the larger network. In the future, he plans to extend this method to elucidate other cortical pathways, such as the ventral visual stream (i.e., the ‘what’ pathway) and the pathways that bridge 3D vision and motor outputs
