Nucleus incertus contribution to the hippocampal theta rhythm generation
The hippocampal theta rhythm is generated by the pacemaker activity of the medial septum-diagonal band of Broca (MS/DBB) neurons. These nuclei are influenced by brainstem structures that modulate the theta rhythm.

Optimized Theta-Join Processing
, 2021 The Theta-Join is a powerful operation to connect tuples of different relational tables based on arbitrary conditions. The operation is a fundamental requirement for many data-driven use cases, such as data cleaning, consistency checking, and hypothesis ...

Frequency dependence of CA3 spike phase response arising from h-current properties [PDF]
, 2013 The phase of firing of hippocampal neurons during theta oscillations encodes spatial information. Moreover, the spike phase response to synaptic inputs in individual cells depends on the expression of the hyperpolarization-activated mixed cation current (

NMDAR‐antibody encephalitis: Seizure semiology and EEG findings
Epileptic Disorders, EarlyView.Abstract Background N‐methyl‐D‐aspartate receptor antibody encephalitis (NMDAR‐Ab‐E) is an autoantibody‐mediated disorder, characterized by acute development of neuropsychiatric symptoms, seizures, movement disorders, and autonomic instability. Objectives To describe acute seizure semiology and electroencephalogram (EEG) findings in patients with a ...

Epileptic Disorders, EarlyView.Abstract The 15q11.2 microdeletion is a chromosomal condition associated with a broad epileptic phenotype. It is differentiated from Angelman syndrome, which is typically a larger maternal deletion in an overlapping area. We describe a patient with a 15q11.2 microdeletion that has clinical and EEG biomarker features similar to those seen in Angelman ...

Theta rhythm recorded in the hippocampal formation in vitro
Postępy Higieny i Medycyny Doświadczalnej, 2013 Theta rhythm is the best synchronized EEG activity that can be recorded in the mammalian brain. Hippocampal formation (HPC) is considered to be the main structure involved in the generation of this activity. Numerous data indicate that theta rhythm is involved in long-term potentiation, spatial learning, spatial navigation, verbal and spatial working ...

Occipital irregular delta activity in focal epilepsy
Epileptic Disorders, EarlyView.Abstract Objective Nonspecific occipital irregular delta activity (OID) is a common finding in focal epilepsy (FE). However, the significance of OID and its relationship to the underlying etiology of FE remain largely unstudied. This study aimed to investigate the relationship between OID and the etiology of FE, as well as the relationship between OID ...

Modeling the contribution of theta-gamma coupling to sequential memory, imagination, and dreaming
Frontiers in Neural CircuitsGamma oscillations nested in a theta rhythm are observed in the hippocampus, where are assumed to play a role in sequential episodic memory, i.e., memorization and retrieval of events that unfold in time.
