Neural lamination is a common feature of the central nervous system (CNS), with several subcellular structures, such as adherens junctions (AJs), playing role in this process. The retina also heavily laminated, but it remains unclear how laminar formation impacts retinal cell morphology, synapse integrity, and overall function. In study, we demonstrate that loss afadin, key component AJs, leads to significant pathological changes. These include disruption outer notable decrease well mislocalization photoreceptors, their segments, photoreceptor synapses. Interestingly, despite these severe impairments, recorded small local field potentials, including a- b-waves. We classified ganglion cells into ON, ON-OFF, OFF types based on firing patterns response light stimuli. Additionally, successfully characterized receptive fields certain cells. Overall, findings provide first evidence circuit function can be partially preserved even when there are disruptions Our results indicate retinas severely altered morphology still retain some capacity process
