Nothing to beat the lethal dose, the American government agency NIH publishes:
The information summarized in this review indicates that exposure to glyphosate, AMPA or GBH could induce several toxic effects on the nervous system of all species studied. Exposure to glyphosate during early life stages can severely affect normal cell development by dysregulating some of the signaling pathways involved in this process, leading to alterations in differentiation, neuronal growth, migration and myelination. Glyphosate also appears to exert a significant toxic effect on neurotransmission, with the glutamatergic system being one of the most affected systems. Glyphosate was found to increase glutamate release and decrease its reuptake, in addition to activating NMDAR and L-VDCC, thereby increasing Ca.2+ influx into neurons. Likewise, the results analyzed here reflect the capacity of glyphosate to induce oxidative stress, neuroinflammation and mitochondrial dysfunction, processes leading to neuronal death by autophagy, necrosis or apoptosis, as well as the appearance of behavioral and motor disorders. . Although there are significant discrepancies between the results analyzed in this review, it is unequivocal that exposure to glyphosate, alone or in commercial formulations, can produce significant alterations in the structure and function of the nervous system of humans. , rodents, fish and invertebrate animals. .
Even the NIH can't lie about how dangerous this shit is anymore, that's saying something!
