Such a sign could determine whether minimally conscious or anesthetized adults are aware—and when consciousness begins in babies. ". You'll also notice that your child may pause after saying what's on his mind, seemingly waiting for a response.

For everyone who's looked into an infant's sparkling eyes and wondered what goes on in its little fuzzy head, there's now an answer. Learn to overcome friendship hurdles and bond with women who get you. Premature babies show very basic electrical activity in the primary sensory regions of the cerebral cortex–those areas that perceive touch, vision, and hearing–as well as in primary motor regions of the cerebral cortex. In babies who were at least 1 year old, Kouider saw an ERP pattern similar to an adult's, but it was about three times slower. Scientists see a spike in brain activity when the senses pick something up, and another signal, the "late slow wave," when the prefrontal cortex gets the message. What are the most important influences on brain development before birth? The team was surprised to see that the 5-month-olds also showed a late slow wave, although it was weaker and more drawn out than in the older babies. Source: Vanderbilt University. Listen for wheezing, hacking, or barking first, then read on to find out what's normal and when it's time to worry.

Your baby will do this most often when he or she is left alone. The wave, feedback from the prefrontal cortex, suggests that the image is stored briefly in the baby's temporary "working memory."
