Second, because it restricts assembly to a small region, there is ample memory to store complicated information about the reads and their relationships.
Importantly, however, the application of RL mechanisms to regulating cognitive control of declarative memory is complicated by several unknowns regarding how value is assigned to memory decisions and outcomes18,19,20,21.
The three-component structure of flash memory makes it overly complicated to connect memory cells vertically.
Early studies have suggested that recognition is intact in PD; 8 nevertheless, a meta-analysis has shown that recognition can be significantly impaired in PD. 9 The process of memory formation is complicated, and single-process models are insufficient at explaining the process fully; therefore, the dual-process model of recognition memory was developed.
Removing memory is more complicated.
"Human memory is so complicated, and we are just barely at the foot of the mountain," Tsien says.
The first Android smartphones could put photos on a removable memory card, which complicated the issue of photo access, he said.
In the Regenstein Center for African Apes, visitors can see some of the gorillas learning complicated memory sequences on a touch screen, part of ongoing research into primate cognition.
Relief workers have complicated memories of humanitarian efforts in places like Somalia and Sudan, Kosovo and northern Iraq, not to mention Afghanistan itself.
The fact that an individual neuron can adapt its firing rate so quickly could help explain how large, dynamic neuronal networks form complicated memories of past events, Fried says.
