This is an audio version of a white broad series covering inhibition/thalamic reticular nucleus. See the video to follow along. Here: https://youtu.be/XLoKW8Wc0Kc?si=xRDdSaFskKB3e5Zb

This episode provides a detailed exploration of the thalamic reticular nucleus (TRN), the inhibitory "shell" surrounding the thalamus that acts as a sensory gate in the brain. Drawing on prior episodes, it explains how abnormalities in TRN development—linked to factors like Sonic Hedgehog signaling knockouts, reduced parvalbumin interneurons, and genes such as CNTNAP2—contribute to the excitation-inhibition imbalance central to autism. The TRN regulates sensory input access (visual, auditory, somatosensory), attention modulat ...
