This study manipulates CaMKII activity in zebrafish retinal rod bipolar cell ribbon synapses to show that both inhibition and elevation impair neurotransmitter release, suggesting optimal CaMKII levels are required for normal function.

The paper uses imaging to study calcium signals in zebrafish retinal bipolar cells, finding variations in local calcium levels related to ribbon size and active zone extent.

This study examines age-related changes in rod bipolar cell ribbon synapses in zebrafish, finding reduced synaptic ribbons and altered calcium dynamics in older fish.
