Journal ArticleDOI

TL;DR: A new dimensionality reduction technique, demixed principal component analysis (dPCA), that decomposes population activity into a few components and exposes the dependence of the neural representation on task parameters such as stimuli, decisions, or rewards is demonstrated.
Journal ArticleDOI
Persistent Spiking Activity Underlies Working Memory.
Christos Constantinidis,Shintaro Funahashi,Shintaro Funahashi,Daeyeol Lee,John D. Murray,Xue-Lian Qi,Min Wang,Amy F.T. Arnsten +7 more
TL;DR: Working Memory: Delay Activity, Yes!
Journal ArticleDOI
Stimulus Selectivity in Dorsal and Ventral Prefrontal Cortex after Training in Working Memory Tasks
TL;DR: The results indicate that regional specialization for stimulus selectivity is present in the primate prefrontal cortex regardless of training.
Journal ArticleDOI
Incorporation of new information into prefrontal cortical activity after learning working memory tasks
TL;DR: These findings help resolve a controversy about whether PFC is innately specialized to process particular types of information or whether its responses are completely determined by task demands by showing there is both regional specialization within PFC that was present before training, as well as more widespread task-relevant information that is a direct result of learning.
Journal ArticleDOI
Comparison of neural activity related to working memory in primate dorsolateral prefrontal and posterior parietal cortex.
Xue-Lian Qi,Fumi Katsuki,Travis Meyer,Justin B. Rawley,Xin Zhou,Kristy L. Douglas,Christos Constantinidis +6 more
TL;DR: Insight is provided on the nature of processing in two areas active during working memory, and on the unique role of the prefrontal cortex in memory maintenance, which is thought to be central to working memory.
