The developing hippocampus plays an important role in episodic memory formation, study finds

Researchers as U. of California, Davis have published a new study in the Journal of Neuroscience that informs the development of children’s memory.

UC Davis’ press release reads in part:

A new study from UC Davis challenges conventional wisdom on the development of memory in children.

The prevailing view has been that changes in how memories are formed as children grow are driven by development of the prefrontal cortex, while the role of the hippocampus, a structure located in the middle of the brain and known to be important for forming and recalling memories, is fixed in early childhood, said Simona Ghetti, associate professor at the UC Davis Department of Psychology and the Center for Mind and Brain.

Instead, a new study by Ghetti and colleagues shows that between the ages of eight and 14, the function of the hippocampus continues to change. The study was published this month in the Journal of Neuroscience.

“The development of prefrontal function is important, but we found that the hippocampus also continues to develop,” Ghetti said.
