Today marks the 25th anniversary (😯) of our publication on discovery of FOXP2. To commemorate, I’ll repost a few prior threads about the gene. Here’s my explainer of how we tracked down FOXP2 & implicated it in speech/language deficits, in the days before completion of the human genome project.🗣️🧬🧪👇

In vivo electrophysiology in head-fixed and freely moving mole-rats
Shirdhankar et al. establish a method to record from single neurons in the brain of African mole-rats while they are head-fixed or freely moving, performing natural behaviors. The method allows the study of sensory perception and neural adaptations of these strictly subterranean rodents, well known for their longevity, cancer resistance, and magnetic sense.

Fish with electrical senses have unique brain cells specifically to process that information. The real trick they pull is separating the electricity they emit from the ones they sense. 🧪 Link: www.nature.com/articles/s41586-026-…
a, Schematic of the interference problem facing the passive electrosensory system of weakly electric fish. Responses of EAFs to prey are masked by responses to the EOD of the fish, which vary depending on factors such as water conductivity. b, Schematic of prediction and cancellation of responses to the EOD. Predictions are based on electric organ corollary discharge signals conveyed by GCs (granule cell basis) and require specific patterns of synaptic connectivity. c, Summary diagram of the synaptic connectivity patterns revealed in the present study. Only connections comprising >10% of the total synapses to a given cell type are shown in the diagram. d, Two example Output cells (blue and red) are shown along with EAF (pink) and GC (magenta) inputs overlaid on a cutout of the EM volume (424 × 427 × 45 µm; all EM connectomic data are from a single biological specimen). The dorsal–ventral and anterior–posterior dimensions of the skin surface are mapped onto the x- and z-dimensions of the volume, respectively. The top inset shows example excitatory GC synapses (magenta fill and star) onto apical dendritic spines of the ON cell (red fill). The magenta fill marks the example GC axon visualized in the volume; the magenta star marks another GC axon.
