Authors show that blocking endogenous Bone Morphogenetic Protein 4 signaling via a selective pharmacological approach promotes oligodendroglial differentiation and increases the rate of remyelination after a central demyelinating insult in vivo.

Authors provide the first functional description of the emergence of neocortical fast ripples in hippocampal epilepsy and show that cross-frequency coupling might be a fundamental mechanism underlying the spreading of epileptic activity.

Figure 1. High-speed confocal imaging and LFP recording in the forebrain of GCaMP-expressing zebrafish larvae. (A) Timeline of confocal imaging and LFP recording relative to immobilization of larvae in agar and exposure to convulsant drugs. High-speed confocal recordings were obtained ∼40 minutes after drug exposure, with 5× and 20× objectives used for whole-brain and single neuron imaging, respectively. (B) Simultaneous high-speed confocal imaging and LFP recording in agar-embedded larvae. (C) Schematic illustration depicting sub-regions of the larval zebrafish brain. (D) Representative 5× image of Tg(neurod1:GCaMP6f) zebrafish at 5–6 days postfertilization. (Adapted from Figure 1 in Liu & Baraban et al., 2019.)

Authors used well-established seizure protocols and fast confocal imaging of genetically encoded calcium indicator-expressing zebrafish to investigate epileptic network properties at brain-wide and single-cell levels.
