Brief embryonic strychnine exposure in zebrafish causes long-term adult behavioral impairment with indications of embryonic synaptic changes

► We treat zebrafish embryos with strychnine and analyze changes in neural synapses at embryonic stages ► We demonstrate changes in embryonic glycinergic and glutamatergic neural synapses in response to strychnine challenge. ► We raise zebrafish embryos treated for short embryonic time windows to adulthood ► We demonstrate changes in behavior in adult fish
