Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech.

Changes posed to the fetus through ethanol exposure may significantly effect growth and development; these are collectively known as fetal alcohol spectrum disorders (FASD). [20] The exact interaction between ethanol and the developing fetus is complex and largely uncertain, however, several direct and indirect effects have been observed as the ...

New research suggests fluoride exposure during pregnancy could be linked to neurobehavioral issues in kids. But even the study’s authors — who were prompted to examine the issue based on ...
Fetal alcohol spectrum disorders are caused by alcohol exposure during gestational development. [1] If an individual was not exposed to alcohol before birth, they will not have FASD. [28] However, not all infants exposed to alcohol in utero will have detectable FAS, FASD, or pregnancy complications. [29]
A June study found that exposure to PFAS in the womb was slightly associated with a risk of obesity in children and adolescents, and research published in 2021 found that exposure to a type of ...
Exposure to nicotine and its great risk of developing an addiction, are areas of significant concern. [ 7 ] Nicotine is a parasympathomimetic stimulant [ 8 ] that binds to and activates nicotinic acetylcholine receptors in the brain, [ 9 ] which subsequently causes the release of dopamine and other neurotransmitters , such as norepinephrine ...
