Early life trauma is a risk factor for later anxiety and alcohol use disorders. However, the role of the post-trauma environment on the development of such disorders is not well understood. In the present study we investigated experience-dependent changes in anxiety and alcohol use after exposure to early trauma. Young mice (day 23) were exposed to a predator odor (synthetic fox pheromone, TMT) and then reared in either standard (SE) or enriched environments (EE). Adolescent anxiety and conditioned fear were reduced in EE-males, but not EE-females. Adult mice were then tested for their preference to drink alcohol. Alcohol intake escalated …

Cognitive neuroscience research suggests that forgetting may depend on which brain areas are supporting a memory, and whether the memory is for meaningful or less meaningful content. The hippocampus is known to represent more vivid recollections of the past, and hippocampal memories appear to decay at the same rate regardless of meaning. In contrast, the medial temporal lobe represents more intuitive feelings of familiarity, and is better at retaining memories for meaningful experiences over time. We sought to test the impact of interference on hippocampal and non-hippocampal memories. We had participants study and recognize a list of random words in …

Spatial memory is an important ability for navigating around one’s surrounding environment. However, due to the challenges of developing experimental paradigms that utilize large scale, real-world environments, little research has analyzed, in detail, the development of cognitive maps over time. Past research in rodents has shown that hippocampal place-cells replay during periods of quiet wakefulness, suggesting that mental replay of recent spatial experiences is tied to the development of cognitive maps. In humans, we hypothesize that the development of cognitive maps could therefore be manipulated by having participants selectively recall recent navigational experiences. We analyzed the development of cognitive maps …
