At #MBL Visual Neuroscience course w/ Anna Jansson @anna_m_neuro, Angel Robles-Gomez & Leonor Afrima. Using 2P microscopy to image transfer of visual signals into & out of bipolar cells in retina of larval zebrafish. Great fun! Thanks to Directors @RichKramerLab & @SchwartzLabNU

The #retina, like other brain circuits, is under modulatory control.
@yesiamohyes and @JosMoyaDaz1 show that "Substance P and dopamine form a “push-pull” system that diurnally regulates retinal gain".

Modulation of retinal gain is accompanied by changes in patterns of vesicle release at the synapses of bipolar cells: increased gain shifts coding of stimulus strength from the rate of release events to their amplitude generated by a process of multivesicular release (MVR).

The actions of substance P reduce the flow of visual information, measured in bits, ∼3-fold. So while dopamine “pushes” the retina to transmit information at higher rates in the afternoon, substance P acts in antiphase to “pull down” information transmission in the morning.

Does reward affect vision? We found neurons in mouse superior colliculus that increase their visual responses after reward. Read more about it in the lab’s first paper with @IntoNeurons and @allemanjm: bit.ly/3zmpe35 #tweeprint (1/7)

James Burke had only one chance to nail this scene. A clip from the 1978 BBC television show Connections, season 1, episode 8, “Eat, Drink, and Be Merry” which could be considered the best timed shot in television history
