Document Summary
The plasticity and malleability of the brain starts at conception and continues after that. There are some experiences that are more powerful than others and can affect how your brain works, even in adulthood. Criti(cid:272)al periods refer to ti(cid:373)e seg(cid:373)e(cid:374)ts of our life (cid:449)here (cid:449)e"re (cid:373)ore sus(cid:272)epti(cid:271)le to the effe(cid:272)ts of e(cid:454)perie(cid:374)(cid:272)e. Experience continually shapes how our brain functions and the connections that are being made. There are positive events that can shape our thinking (not only negative events) Embryogenesis is the process by which an embryo forms and develops. In the beginning, it starts with a single zygote (sperm and egg together two half-cell entities that come together to quickly divide) )(cid:455)gotes are(cid:374)"t (cid:272)o(cid:374)sidered fetuses u(cid:374)til arou(cid:374)d (cid:1005)(cid:1006) (cid:449)eeks after (cid:272)o(cid:374)(cid:272)eptio(cid:374) Every differentia feature we have starts with a generic starting feature the zygote.
