Judging the difficulty of perceptual decisions

Kavli Affiliate: Michael Shadlen | Authors: Anne Löffler, Ariel Zylberberg, Michael N. Shadlen and Daniel M Wolpert | Summary: Deciding how difficult it is going to be to perform a task allows us to choose between tasks, allocate appropriate resources, and predict future performance. To be useful for planning, difficulty judgments should not require completion […]

Random noise promotes slow heterogeneous synaptic dynamics important for robust working memory computation

Kavli Affiliate: Terrence Sejnowski | Authors: Nuttida Rungratsameetaweemana, Robert Kim, Thiparat Chotibut and Terrence Sejnowski | Summary: Recurrent neural networks (RNNs) based on model neurons that communicate via continuous signals have been widely used to study how cortical neurons perform cognitive tasks. Training such networks to perform tasks that require information maintenance over a brief […]

Cross-Modal Representation of Identity in Primate Hippocampus

Kavli Affiliate: Cory Miller | Authors: Timothy Tyree, Michael Metke and Cory Miller | Summary: Faces and voices are the dominant social signals used to recognize individuals amongst human and nonhuman primates (1–4). Yet it is not known how these critical signals are integrated into a cross-modal representation of individual identity in the primate brain. […]
