Neural Memory traces are formed by listening and learning prior to birth


A cognitive neuroscientist from University of Helsinki, Dr. Eino Partanen led a team to show direct neural evidence that neural memory traces are formed by auditory learning prior to birth. Neural memory traces are formed by listening and learning.  Fetuses were exposed to various words inside the uterus and they showed recognition of these words on birth with enhanced brain activity measurements for the trained words.  Furthermore, greater brain activity was correlated with higher amount of prenatal speech exposure (Read original article here). Simply stated, it means that talking or singing to the baby inside the womb will help the baby develop it’s brain commited to speech features.

Implications in Autism?
These results have important implications for Autism prevention in susceptible communities. Perhaps, prevention education might need to begin during prenatal stage? Along with Vitamin D exposure from sunlight, supplements and nutrition of the parents. Recent studies report Vitamin D plays a role in compensating for stress induced deteriorating effects on the brain.

Neural commitment to speech begins before birth
Until this August 2013 publication by Dr. Partanen’s team, the neural basis of fetal learning had not thus far been investigated. This research will aid scientists learning to compensate for learning disabilities of a genetic nature such as dyslexia. It might also imply that it is important to compensate with early learning and listening protocols for genetically susceptible offsprings while still inside the uterus.

Learning begins while Baby is still inside the uterus and factors can stress them

This baby began to learn at 17 weeks of age inside the uterus and may have been exposed to mother's stress hormones

This baby began to learn at 17 weeks of age inside the uterus with prenatal speech exposure and may have been exposed to mother’s stress hormones

Dr. Gail Cross reviewed a few research studies on prenatal learning for Huffington Post here that inform us the developing brain is very sophisticated in utero. Christie Moon, Ph.D., a psychologist at Pacific Lutheran University in Tacoma, Washington and Dr. Hugo Lagercrantz, a professor at the Karalinska Institute in Sweden and a member of the Nobel Assembly co-authored the first study measurably showing the neurosensory mechanism for hearing is intact at 30 weeks of gestational age, while still in the mother’s womb. Dr. Vivette Glover of Imperial College of London was the first to note the early stage in which a mother’s stress and anxiety might affect an unborn baby. Stress hormones of the mother can cross the placenta, affect the dopamine production of the developing fetus brain around 17 weeks of age, and cause a baby to stress more easily with long term lasting effects.
