Thalamus Actively Helps Wire Visual Circuits, Mouse Study Finds
Key Takeaways
- A team led by Guillermina López-Bendito at the Institute for Neurosciences (IN CSIC-UMH) found that the thalamus's own activity helps organize visual circuits during development.
- Published in The Journal of Neuroscience, the study used mouse models in which neuronal activity was altered at different points along the visual pathway and at different developmental stages.
- Altering thalamic activity changed the number and distribution of interneurons in the visual thalamus and affected their organization in the visual cortex.
- The thalamus is known as a relay between the retina and visual cortex, but the results indicate it also plays an active role in circuit formation.
