What happens if a baby of the age of about 1yr old drinks a small mouth full of beer just say one day and then a day the next week and a day or 2 after wards, or instead of taking a mouth of it dips her soother in a glass of beer 2 or 3 times? How would it effect their brain?

1. during neurulation right after gastrulation early neuronal structures arise from the ectoderm

2. nicotine stimulated acethylcholine receptors in the brain, the effects after birth that have been described in studies using mice

are similar to those seen in epidemiological studies in humans

a general feature is that these children are hyperactive and more stressed
