…some epidemiological surveys involving a broad range of traumatic exposures have shown that the twofold greater risk for PTSD in women cannot be accounted for by greater exposure to trauma, even when accounting for prior history of victimization or abuse. Continue reading

OhOh! “Studies revealed that approximately 70% of adult women in the United States had been exposed to a serious trauma, and the majority of the population regardless of sex experienced exposure to at least one traumatic event in their lifetime. Studies from multiple countries have reported similarly high estimates of trauma exposure20–

“connections in the brain are so densely packed, state-of-the-art imaging can only begin to scratch the surface.”

“We found a synapse approximately every cubic micron,” Lichtman said. “That means if you look at images of the brain captured using high-resolution techniques like functional magnetic resonance imaging, where the pixel size represents one cubic millimeter, then there are one billion synapses within every pixel.”

It may be there, in that staggering density, he said, that the study’s final message lies.

“It’s very hard to get a complete feeling for this,” Lichtman said. “There is this naïve view that if you just know a little bit more, then understanding it will be easier, but in this case, knowing a little more has shown us how much further we have to go before we’ll understand brains.”
