Another direction of future research is to tie decay theory to sound neurological evidence. As most current evidence for decay leaves room for alternate explanations, studies indicating a neural basis for the idea of decay will give the theory new solid support. Jonides et al. (2007) found neural evidence for decay in tests demonstrating a general decline in activation in posterior regions over a delay period. <ref name="jonref"> Jonides, J., Lewis, R.L., Nee, D.E., Lustig, C.A., Berman, M.G., & Moore, K.S. (2007) The Mind and Brain of Short Term Memory [Electronic Version]. Annual Review of Psychology, 59, pp. 193-224. Retrieved March 2, 2010</ref> Though this decline was not found to be strongly related to performance, this evidence is a starting point in making these connections between decay and neural imaging.

A model proposed to support decay with neurological evidence places importance on the firing patterns of neurons over time.<ref name="jonref" />The neuronal firing patterns that make up the target representation fall out of synchrony over time unless they are reset. The process of resetting the firing patterns can be looked at as rehearsal, and in absence of rehearsal, forgetting occurs. SaidThis proposed model needs to be tested further to gain support, and bring firm neurological evidence to the decay theory.<ref name="jonref" />
