An Optimised Method for Robust Golgi Cox Staining in Cortical Neurons

Golgi-based staining remains a valuable method for visualising the full morphology of individual neurons, however conventional workflows can be slow, variable, and technically demanding. Here, we present a modified staining protocol designed to provide a practical workflow for Golgi-based labelling in mouse cortical tissue. The revised workflow combines controlled fixation, dichromate impregnation, silver development, vibratome sectioning, and slide processing conditions that support visualisation of neuronal somata and dendritic architecture. In the tissue examined here, the protocol produced stained tissue with discernible neuronal morphology and was suitable for morphological assessment using standard light microscopy and image analysis software. Overall, this method may be useful for laboratories seeking a straightforward and cost-conscious protocol for neuronal morphology.

Psilocybin ameliorates neuropathic pain-like behaviour in mice and facilitates gabapentin-mediated analgesia

Chronic pain states are challenging to control with current drug therapies. Here, we demonstrate that a single dose of psilocybin can produce a sustained anti-nociceptive effect in a model of chronic neuropathic pain in male and female mice. Psilocybin anti-nociceptive effects were mediated by 5-HT2A receptors, although additional mechanisms might also be involved. Furthermore, a single dose of psilocybin caused a significant increase in the anti-nociceptive potential of gabapentin, a widely used treatment for neuropathic pain consistent with the establishment of longer lasting changes in network processing. Overall, these findings present the first preclinical evidence that psilocybin could be a valuable approach for treating chronic pain from nerve injury and serve as a new therapeutic addition for pain management.
