Mice Inherit Specific Memories, Because Epigenetics?

Two weeks ago I wrote about some tantalizing research coming out of the Society for Neuroscience meeting in San Diego. Brian Dias, a postdoctoral fellow in Kerry Ressler’s lab at Emory University, had reported that mice inherit specific smell memories from their fathers — even when the offspring have never experienced that smell before, and even when they’ve never […]…

Epigenetics and the Brain: Woo-free Coolness

In my latest column for Discover, I take a look at epigenetics and the brain. Along with the genetic circuitry in the DNA of our brain cells, we also have an additional layer of molecules that can switch genes on and off. A lot of this so-called epigenome gets locked into place when our brains […]…

From Ancient Genomes to Ancient Epigenomes

Late last year, scientists unveiled the complete genome of a female Neanderthal whose 130,000-year-old toe bone had been found in a cave in Siberia. As it turned out, her sequence of some 3 billion DNA letters was not all that much different from mine or yours. The researchers identified only about 35,000 places in the […]…

The Chatty Hippocampus

The hippocampus, a skinny log of brain tissue tucked in deep above your ear, is the star of memory research. People with damaged hippocampi — such as the famous patient Henry Molaison, known as H.M. — can’t make new memories. And studies in rodents have shown that creating new memories drives robust connections between neurons […]…

A diagnosis of autism is almost five times more common in boys than girls. But a new study suggest the sex differences in autism have been greatly exaggerated…
