My postdoc work at Isaac Bianco's lab is finally out on @eLife !
https://elifesciences.org/articles/78381

Combining #lightsheet volumetric functional imaging and a spiking network simulation, we were able to show that a simple connectivity motif in the #zebrafish #optictectum explains multiple features in ongoing population dynamics, their impact on trial-to-trial variability, and trends in experience dependent behavior.

It is a neat example of how #networkdynamics can explain why neuronal and behavioural responses vary, or how past activity sets the ever-changing background for new input (that, in turn, will make its own long-lasting splash)

Recurrent network interactions explain tectal response variability and experience-dependent behavior

Recurrent interactions in the optic tectum underlie activity-dependent changes in network state that account for variability in sensory encoding and behavior.

Sierra Dixon, Bailey Calder &co show that valproic acid exposure leads to a delay in #zebrafish optic tectum #neurogenesis and #neuron specification:

“Overall, our findings provide an initial characterisation of the deviances in development of the optic tectum in an Autism model”

Valproic acid affects neurogenesis during early optic tectum development in zebrafish

Summary: Optic tectum (OT) is a midbrain structure that is important in integrating multimodal input and guides non-voluntary movements in response to prevalent stimuli. Here we show that valproic acid, associated with autism spectrum disorder, leads to a delay in OT's neurogenesis and neuron specification.
