Most people think hearing is about volume – how loud a sound is or whether it gets through. But new research shows that what really matters is timing. In this installment of our Senses series, we look at new work showing how: Brainstem neurons rely on voltage-gated potassium channel 4 (Kv4) to preserve sub-millisecond spike fidelity. Efferent inhibition delays responses to protect against noise overload. Gene therapy can restore structural timing cues in the cochlea. Loss of

ALOMONE LABS NEWS A new study in Nature Cell Biology revealed that neural stem cells (NSCs) aren’t limited to the brain and spinal cord. Researchers identified multipotent peripheral NSCs (pNSCs) in the lung, tail, and dorsal root ganglia that self-renew, express canonical markers, and differentiate into neurons and glia – without reprogramming. Remarkably, these neurons are electrically active, showing voltage-gated sodium and potassium currents, with the sodium current full
