The parts of the fetal brain that control movement will not fully form until late in the second trimester, and the first part of the third trimester. [7] Control of movement is limited at birth, and purposeful voluntary movements develop during the long period up until puberty. [ 8 ]
With the brain, this process happens early in development, again during puberty, and pregnancy probably reflects another wave of cortical refinement.” Increase in brain white matter during pregnancy
Fetal electroencephalography, also known as prenatal EEG includes any recording of electrical fluctuations arising from the brain of a fetus. Doctors and scientists use EEGs to detect and characterize brain activity, such as sleep states, potential seizures, or levels of a coma. EEG captures the electrical activity in the vicinity of the ...
During the first phase, in the first six months after conception, general architecture of brain regions is largely formed by a burst of genetic activity, which is distinct for specific regions of the neocortex. This rush is followed by a sort of intermission beginning in the third trimester of pregnancy.
The first trimester is from conception to 12 weeks of pregnancy, the second trimester is from 13 to 28 weeks of pregnancy, and the third trimester is from 29 weeks until birth. During the prenatal phase, the fetus is developing the structures to carry out cognitive functions, such as brain cells, brain waves, and forming the lobes and other ...
Crystal Methamphetamine is an example of a recreational drug that can have serious negative consequences on fetal memory development if used during pregnancy. Similarly to nutritional intake, drugs consumed by the mother during pregnancy can affect the brain development of her fetus.
If the fetus is asleep throughout gestation then the possibility of fetal pain is greatly minimized, [14] [15] although some studies found that the adenosine levels in third-trimester fetuses are only slightly greater than those in adults' blood. [16]
Final embryonic stage, after this development is described as "fetal" through the entire second and third trimester. Mesoderm: ossification continues Head: eyelids, external ears, rounded head Body: straightening of trunk, intestines herniated at umbilicus Limbs: hands and feet turned inward
