{"doi":"10.1101/2023.12.22.573160","title":"News without the buzz: reading out weak theta rhythms in the hippocampus","abstract":"Abstract Local field potentials (LFPs) reflect the collective dynamics of neural populations, yet their exact relationship to neural codes remains unknown 1 . One notable exception is the theta rhythm of the rodent hippocampus, which seems to provide a reference clock to decode the animal’s position from spatiotemporal patterns of neuronal spiking 2 or LFPs 3 . But when the animal stops, theta becomes irregular 4 , potentially indicating the breakdown of temporal coding by neural populations. Here we show that no such breakdown occurs, introducing an artificial neural network that can recover position-tuned rhythmic patterns (pThetas) without relying on the more prominent theta rhythm as a reference clock. pTheta and theta preferentially correlate with place cell and interneuron spiking, respectively. When rats forage in an open field, pTheta is jointly tuned to position and head orientation, a property not seen in individual place cells but expected to emerge from place cell sequences 5 . Our work demonstrates that weak and intermittent oscillations, as seen in many brain regions and species, can carry behavioral information commensurate with population spike codes.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2023,"id":402052,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9469,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1179429,"name":"Brian Lustig","orcid":"0000-0002-3105-6766","position":1,"is_corresponding":false},{"id":1179745,"name":"Seiji Akera","orcid":null,"position":2,"is_corresponding":false},{"id":1179430,"name":"Eva Pastalkova","orcid":"0000-0001-5518-9590","position":3,"is_corresponding":false},{"id":614638,"name":"Albert K.
