Definition: The layer within the retina where the bipolar cells synapse with the photoreceptor cells.
Ontology: Anatomy Ontology [ZFA:0001330]
Name: dendritic spine
Synonyms: branched dendritic spine, dendrite spine, mushroom dendritic spine, sessile dendritic spine, stubby dendritic spine, thin dendritic spine
Definition: A small, membranous protrusion from a dendrite that forms a postsynaptic compartment - typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable including "thin", "stubby", "mushroom", and "branched", with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.
