When does a fetus have brain activity?

Best Answers

Yes, indeed. At that age, the fetus brain is growing unbelievably fast, and the brain's neurons are making connections already. At that age, the fetus brain is growing unbelievably fast, and the brain's neurons are making connections already. read more

The definition of death is not disputed, and is considered the time when electroencephalography (EEG) activity ceases. EEG measures brain activity and must demonstrate regular wave patterns to be considered valid. Therefore, by this rule the onset of life would be the time when fetal brain activity begins to exhibit regular wave patterns, which occurs fairly consistently around week 25. Previous to that time, the EEG only shows small bursts of activity without sustained firing of neurons. read more

After showing they could successfully quantify brain activity in moving subjects, they then scanned eight fetuses between 32 and 37 weeks of pregnancy, as infants born prematurely at that age have been shown to have active default mode networks. The resulting images were compiled to create a four-dimensional view of each of the brains over a five-minute time window. read more

New technology reveals fetal brain activity Method makes imaging of moving subjects possible NIBIB-funded researchers at the University of Washington have pioneered an approach to image functional activity in the brains of individual fetuses, allowing a better look at how functional networks within the brain develop. read more

The brain of a person in love will show activity in the amygdala, which is associated with gut feelings, and in the nucleus accumbens, an area associated with rewarding stimuli that tends to be active in drug abusers. Or, to recap: the brain of a person in love doesn't look like the brain of someone overcome by deep emotion. It looks like the brain of a person who's been snorting coke.
