Can the adult hippocampal plasticity withstand a gut microbiome insult? @jfcryan et al. found that hippocampal long-term potentiation, short-term plasticity, or basal synaptic efficacy are resilient to microbiome depletion in adulthood @EJNeuroscience  onlinelibrary.wiley.com/doi/…

Robust Hippocampal Synaptic Plasticity Despite Gut Microbiota Depletion in Adult Mice

Microbiota depletion in adulthood does not alter hippocampal synaptic function in male and female mice. We investigated whether short-term depletion of the gut microbiota in adulthood alters hippoc...
