Alice Berners-Lee, Xiaojing Wu, David J Foste. Prefrontal cortical neurons are selective for non-local hippocampal representations during replay and behavior. The Journal of neuroscience : the official journal of the Society for Neuroscience vol issue 2022 34035138 Thus, PFC activity that is tuned to HP activity is best explained by non-local HP position representations rather than HP representation of actual position, providing a new potential mechanism of HP-PFC coordination during HP replay. 2022-01-08 2022-01-09 rat
Anna Li, Yaling Liu, Qiaosheng Zhang, Isabel Friesner, Hyun Jung Jee, Zhe Sage Chen, Jing Wan. Disrupted population coding in the prefrontal cortex underlies pain aversion. Cell reports vol 37 issue 6 2021 34758316 These results suggest a dynamic resource allocation mechanism in the prefrontal representations of pain and indicate that population activity in the PFC critically regulates pain and serves as an important therapeutic target. 2021-12-24 2022-01-08 rat
Matthieu X B Sarazin, Julie Victor, David Medernach, J\\xc3\\xa9r\\xc3\\xa9mie Naud\\xc3\\xa9, Bruno Delor. Online Learning and Memory of Neural Trajectory Replays for Prefrontal Persistent and Dynamic Representations in the Irregular Asynchronous State. Frontiers in neural circuits vol 15 issue 2021 34305535 Together, these results offer a consistent theoretical framework accounting for how neural trajectories can be learned, memorized and replayed in PFC networks circuits to subserve flexible dynamic representations and adaptive behaviors. 2021-12-23 2022-01-08 Not clear
Roshan Cools, Amy F T Arnste. Neuromodulation of prefrontal cortex cognitive function in primates: the powerful roles of monoamines and acetylcholine. Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology vol 47 issue 1 2021 34312496 Brain imaging studies in humans have observed drug and genotype influences on a range of cognitive tasks and on PFC circuit functional connectivity, e.g., showing that catecholamines stabilize representations in a baseline-dependent manner. 2021-12-12 2022-01-08 monkey
Yu-Xiang Zhang, Bo Xing, Yan-Chun Li, Chun-Xia Yan, Wen-Jun Ga. NMDA receptor-mediated synaptic transmission in prefrontal neurons underlies social memory retrieval in female mice. Neuropharmacology vol 204 issue 2021 34813859 It is also unclear to what extent the neuronal representations of social memory formation and retrieval events overlap in the prefrontal cortex (PFC) and which event drives social memory strength. 2021-12-11 2022-01-08 mouse
D Durstewitz, J K Seamans, T J Sejnowsk. Dopamine-mediated stabilization of delay-period activity in a network model of prefrontal cortex. Journal of neurophysiology vol 83 issue 3 2000 10712493 To further test this idea and to examine the dopamine-modulated ionic currents that could give rise to increased stability of neural representations, we developed a network model of the PFC consisting of multicompartment neurons equipped with Hodgkin-Huxley-like channel kinetics that could reproduce in vitro whole cell and in vivo recordings from PFC neurons. 2000-04-11 2022-01-08 Not clear
D Durstewitz, J K Seamans, T J Sejnowsk. Dopamine-mediated stabilization of delay-period activity in a network model of prefrontal cortex. Journal of neurophysiology vol 83 issue 3 2000 10712493 Recently we proposed that dopamine might stabilize active neural representations in PFC circuits during tasks involving working memory and render them robust against interfering stimuli and noise. 2000-04-11 2022-01-08 Not clear
D Durstewitz, J K Seamans, T J Sejnowsk. Dopamine-mediated stabilization of delay-period activity in a network model of prefrontal cortex. Journal of neurophysiology vol 83 issue 3 2000 10712493 In conclusion, the dopamine-induced changes in the biophysical properties of intrinsic ionic and synaptic conductances conjointly acted to highly increase stability of activated representations in PFC networks and at the same time retain control over network behavior and thus preserve its ability to adequately respond to task-related stimuli. 2000-04-11 2022-01-08 Not clear
B Rypma, M D'Esposit. The roles of prefrontal brain regions in components of working memory: effects of memory load and individual differences. Proceedings of the National Academy of Sciences of the United States of America vol 96 issue 11 1999 10339627 It was observed that dorsal PFC plays a differentially greater role in information retrieval for slower subjects, possibly because of inefficient retrieval processes or a reduced quality of mnemonic representations. 1999-06-24 2022-01-08 human
D Durstewitz, M Kelc, O G\\xc3\\xbcnt\\xc3\\xbcrk\\xc3\\xbc. A neurocomputational theory of the dopaminergic modulation of working memory functions. The Journal of neuroscience : the official journal of the Society for Neuroscience vol 19 issue 7 1999 10087092 Here, the hypothesis is put forward that the functional role of dopamine in working memory processing is to stabilize active neural representations in the PFC network and thereby to protect goal-related delay-activity against interfering stimuli. 1999-04-13 2022-01-08 Not clear
J D Cohen, T S Braver, R C O'Reill. A computational approach to prefrontal cortex, cognitive control and schizophrenia: recent developments and current challenges. Philosophical transactions of the Royal Society of London. Series B, Biological sciences vol 351 issue 1346 1997 8941963 In particular, we focus on refinements concerning the mechanisms underlying active maintenance of representations within PFC, and the characteristics of these representations that allow them to support the flexibility of cognitive control exhibited by normal human behaviour. 1997-04-11 2022-01-07 human
