    behind the talk. Several studies support that the hippocampus is highly engaged to train information across brief periods of time and activating the hippocampus contributes to subsequent memory performance. Hippocampal activation can even predict subsequent memory during the acquisition of new information. The evidence found for amnesia being an impairment of declarative and episodic memory is that amnesia associated with damage to the hippocampus is selective to declarative memory, for example…

    that the hippocampus plays no role on memories that have existed for an extended period of time. For example, Bayley et al.

These phenomena have since received a lot of attention and they currently constitute the two major cellular models for investigating synaptic plasticity (Howland and Wang,…

    Memory is an area of cognition that is thought to both be affected by, and be an integral part of the substance abuse cycle. Whereas addiction was once believed to be attributed to a lack of willpower, or flaws of character, much of the current understanding realizes it is a complex interplay between individual genetic, biological, developmental, and environmental characteristics (Koob & Volkow, 2009). The overreaching scope of this paper is to examine the connections between addiction and…
