The direction-selective circuit in the retina adjusts the contributions of excitatory and inhibitory mechanisms under different stimulus conditions to generate context-dependent neural representations of visual features.
Computational modeling and a cell cycle-reporting axolotl reveal how spinal cord regeneration can be achieved by a signal that propagates 828 μm from the injury site during the first 85 hours post-amputation.
Proximity labeling-based proteomic strategies applied in zebrafish identify new insights into protein network changes in heart muscle cells during regeneration and implicate Rho A as a target of ErbB2 signaling during zebrafish heart regeneration.
To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.
A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.
