Different theta frameworks coexist in the rat hippocampus and are coordinated during memory-guided and novelty tasks

open access: yeseLife, 2020
Hippocampal firing is organized in theta sequences controlled by internal memory processes and by external sensory cues, but how these computations are coordinated is not fully understood.

Spike frequency adaptation affects the synchronization properties of networks of cortical oscillators [PDF]

open access: yes, 1997
Oscillations in many regions of the cortex have common temporal characteristics with dominant frequencies centered around the 40 Hz (gamma) frequency range and the 5–10 Hz (theta) frequency range.

Short‐Term Scheduling Optimization of a Single‐Pipeline Refining System With High Melting Point Crude Oil

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reflect the actual production situation more comprehensively and optimize the production cost, this paper solves the short‐term scheduling optimization problem for a single pipeline containing high melting point crude oil. Based on the refining plan given by the upper layer, a multi‐objective optimization model with high melting ...

Closed-Loop Transcranial Ultrasound Stimulation for Real-Time Non-invasive Neuromodulation in vivo

open access: yesFrontiers in Neuroscience, 2020
The closed-loop brain stimulation technique plays a key role in neural network information processing and therapies of neurological diseases. Transcranial ultrasound stimulation (TUS) is an established neuromodulation method for the neural oscillation in

Single-Trial Phase Precession in the Hippocampus [PDF]

open access: yes, 2009
During the crossing of the place field of a pyramidal cell in the rat hippocampus, the firing phase of the cell decreases with respect to the local theta rhythm.

Theta Rhythm: Temporal Glue for Episodic Memory [PDF]

open access: yesCurrent Biology, 2017
The low frequency theta rhythm is thought to promote the formation of long-term multimodal memories in the hippocampus by orchestrating input from multiple cortical sources. New research has demonstrated a causal association between the timing of experimentally induced theta rhythms and episodic memory formation in humans.

Epilepsy characteristics in patients with muscle‐eye‐brain disease: A systematic review of electroclinical features

open access: yesEpileptic Disorders, EarlyView.
Abstract Background and Objectives Muscle‐Eye‐Brain disease (MEB) is a dystroglycanopathy that belongs to the congenital muscular dystrophies. Central nervous system manifestations include congenital brain abnormalities, neurodevelopmental delay, and epilepsy, making it a rare but important cause of developmental and epileptic encephalopathy.

Theta Oscillations and Reactivity of Hippocampal Stratum Oriens Neurons

open access: yesThe Scientific World Journal, 2010
The supposition was advanced that the neuronal theta rhythmicity is the key mode of signal selection at the hippocampal level. To address this hypothesis, the experimental data on the responses of putative hippocampal interneurons of the stratum oriens ...

Irregular speech rate dissociates auditory cortical entrainment, evoked responses, and frontal alpha [PDF]

open access: yes, 2015
The entrainment of slow rhythmic auditory cortical activity to the temporal regularities in speech is considered to be a central mechanism underlying auditory perception.

Theta rhythm and the encoding and retrieval of space and time [PDF]

open access: yesNeuroImage, 2014
Physiological data demonstrates theta frequency oscillations associated with memory function and spatial behavior. Modeling and data from animals provide a perspective on the functional role of theta rhythm, including correlations with behavioral performance and coding by timing of spikes relative to phase of oscillations.
