And just a little bit on lead here, lead exposure, it interferes with brain growth. It disrupts neuron functioning. And from that it impairs intelligence, even emotional regulation, even various cognitive states beyond that. And facelift, with all this evidence, researchers began to question how modern humans managed to thrive despite these toxic conditions during their evolutionary past. So they started looking a little bit deeper, and there's a gene, there's a gene. It's known as a neural, phonical logical, a ventral antigen, one. Or I'll just refer to this as NOVA1, as I go on with this. It has a major role in brain formation and synaptic development. And it's a key regulator in neurodevelopment. So NOVA1 helps determine how neuro, for genit, uh, finisher cells react to lead exposure. And the services and its activity are linked to neurological disorders.
