Stability and Wandering of Bumps in Neural Fields with Interneuron Subtypes
Bilal Ahmed, Heather Cihak, Gregory Handy
The maintenance of continuous variable information in working memory is thought to rely on persistent patterns of cortical activity. In delayed-estimation tasks, neural activity ca…
Astrocytic resource diffusion stabilizes persistent activity in neural fields
Noah Palmer, Heather L. Cihak, Daniele Avitabile +1
Persistent neural activity underlying working memory requires sustained synaptic transmission, yet the metabolic and neurotransmitter support provided by astrocyte networks is larg…
Robustly encoding certainty in a metastable neural circuit model
Heather L Cihak, Zachary P Kilpatrick
Localized persistent neural activity can encode delayed estimates of continuous variables. Common experiments require that subjects store and report the feature value (e.g., orient…
Distinct excitatory and inhibitory bump wandering in a stochastic neural field
Heather L Cihak, Tahra L Eissa, Zachary P Kilpatrick
Localized persistent cortical neural activity is a validated neural substrate of parametric working memory. Such activity `bumps' represent the continuous location of a cue over se…
