Concept information
Preferred term
neurogenic hypthothesis
Definition
- The hypothesis proposed by Josselyn and Frankland (2012) to explain infantile amnesia. The hippocampus of infants (humans, non-human primates, and rodents) undergoes a high level of neurogenesis, resulting in the replacement of existing synaptic connections in hippocampal memory circuits (neural networks in the hippocampus that encode memories). Therefore, this high level of neurogenesis is accompanied by an inability to form stable long-term memories. When the level of neurogenesis decreases, the formation of long-term memories becomes possible.
