Dynamic parallel memories

Dynamic Parallel Memories

Say that a parallel algorithm that uses $p$ processors and $N(>p)$ shared memory locations is given. The problem of simulating this algorithm by $p$ processors and only $p$ shared memory locations without increasing the running time by more than a constant factor is considered. A solution for a family of such parallel algorithms is given. The solution utilizes the idea of dynamically changing l...

Dynamic Organization of Hierarchical Memories

In the brain, external objects are categorized in a hierarchical way. Although it is widely accepted that objects are represented as static attractors in neural state space, this view does not take account interaction between intrinsic neural dynamics and external input, which is essential to understand how neural system responds to inputs. Indeed, structured spontaneous neural activity without...

Parallel processing of olfactory memories in Drosophila.

One of the hallmarks of both memory and the underlying synaptic plasticity is that they each rely on short-lived and longer-lived forms. Short-lived memory is thought to rely on modification to existing proteins, whereas long-term memory requires induction of new gene expression. The most common view is that these two processes rely on signaling mechanisms within the same neurons. We recently d...

Dynamic memories of the collective past

In this paper, I first retrace some aspects of a dynamic theory of humans in society, and then highlight what appear to me as major contributions of two papers of this special issue. This leads me to highlight a series of questions, which I address through two other consonant studies on remembering, the work of Harald Welzer and his team on the memory of WWII in three generations in German fami...
