  abstract     = {For accurate perception and motor control, an animal must distinguish between sensory experiences elicited by external stimuli and those elicited by its own actions. The diversity of behaviors and their complex influences on the senses make this distinction challenging. Here, we uncover an action–cue hub that coordinates motor commands with visual processing in the brain’s first visual relay. We show that the ventral lateral geniculate nucleus (vLGN) acts as a corollary discharge center, integrating visual translational optic flow signals with motor copies from saccades, locomotion and pupil dynamics. The vLGN relays these signals to correct action-specific visual distortions and to refine perception, as shown for the superior colliculus and in a depth-estimation task. Simultaneously, brain-wide vLGN projections drive corrective actions necessary for accurate visuomotor control. Our results reveal an extended corollary discharge architecture that refines early visual transformations and coordinates actions via a distributed hub-and-spoke network to enable visual perception during action.},

  abstract     = {Biological vision is unlike a camera; rather than transmitting light information faithfully, early
visual circuits process the visual scene to convey only the relevant information in an efficient
manner. Consequentially, the nature of this visual processing then depends on what is the
relevant information in a scene and on the notion of efficiency. In this work, I study how visual
processing is modulated by two different variations in the visual scene. First, I discovered that
in the mouse (Mus musculus) retina, Retinal Ganglion Cells in the upper and lower visual
field have differences in the center surround structure of their receptive fields. Comparison
with models of efficient coding show that this adaptation likely evolved to cope with the
brightness gradient from the sky to the ground that is pervasive in natural scenes. In the
second project, I study how the downstream neurons in the Superior Colliculus dynamically
change their temporal selectivity depending on the ambient luminance and behavioral state.
As the scene gets darker or when the animal is is less aroused, the neuronal responses get
laggier, while still maintaining their relative timing with respect to the population. Overall, this
work emphasises the need to understand visual processing in the context of specific demands
of the animal in its the environment. The adaptive changes in the visual system, from the
retinal ganglion cells to the superior colliculus, highlight the intricate ways in which biological
vision optimizes the processing of visual information.
