Topic: prefrontal areas

Both the formation and retrieval of episodic memories are closely associated with the activation of the hippocampal complex and medial temporal lobe (MTL) areas. These areas however are not sufficient by themselves to support most episodic memory functions. Instead, MTL areas are embedded as a central hub into a more distributed cortical network that supports both the storing, consolidation and subsequent reactivation of memories. Recently emerging evidence however indicates that cortical areas like posterior parietal regions and prefrontal areas contribute more to the processes than previousl

Reaction time (RT), that is the time it takes for an action plan to be executed, has been the interested of numerous studies. Of particular focus has been the RT in the context of perceptual ambiguities, when evidence towards taking a certain action must be integrated over time in order to execute the correct action. The stochastic drift diffusion model explains how such integration leads to the observed variability in RT, but what explains RT variability in a task where there is no ambiguity in what action will be rewarded?We trained recurrent neural network models to perform a delayed memory
