Case Report: non-monotonic longitudinal RSWA with tonic–phasic dissociation across serial attended video-polysomnography in isolated REM sleep behaviour disorder [PDF]

Frontiers in Sleep
BackgroundQuantitative REM sleep without atonia (RSWA) metrics are increasingly used to characterize isolated REM sleep behavior disorder (iRBD) and as candidate biomarkers.

Hybrid Adaptive Segmentation and Morphology-Based Classification of EOG for Automated Detection of Phasic and Tonic REM Sleep [PDF]

Sensors
Rapid eye movement (REM) sleep is increasingly understood as a heterogeneous state composed of two neurophysiologically distinct microstates: tonic REM and phasic REM. Phasic REM, defined by brief clusters of saccadic eye movements and transient cortical

Extrasynaptic δ-subunit containing GABAA receptors [PDF]

Journal of Integrative Neuroscience, 2021
γ-Aminobutyric acid type A receptors (GABAARs) are GABA gated heteropentameric chloride channels responsible for the adult brain’s primary inhibition.

Phasic and Tonic Locus Coeruleus Stimulation Associated Valence Learning Engages Distinct Adrenoceptors in the Rat Basolateral Amygdala

Frontiers in Cellular Neuroscience, 2022
Reward exploitation and aversion are mediated in part by the locus coeruleus (LC), a brainstem structure significantly involved in learning and memory via the release of norepinephrine. Different LC firing patterns are associated with different functions.

Botulinum neurotoxin accurately separates tonic vs. phasic transmission and reveals heterosynaptic plasticity rules in Drosophila

eLife, 2022
In developing and mature nervous systems, diverse neuronal subtypes innervate common targets to establish, maintain, and modify neural circuit function. A major challenge towards understanding the structural and functional architecture of neural circuits

Temporal Summation in Fibromyalgia Patients: Comparing Phasic and Tonic Paradigms

Frontiers in Pain Research, 2022
IntroductionFibromyalgia (FM) is associated with dysfunctional pain modulation mechanisms, including central sensitization. Experimental pain measurements, such as temporal summation (TS), could serve as markers of central sensitization and have been ...

Synaptic Properties and Plasticity Mechanisms of Invertebrate Tonic and Phasic Neurons

Frontiers in Physiology, 2020
Defining neuronal cell types and their associated biophysical and synaptic diversity has become an important goal in neuroscience as a mechanism to create comprehensive brain cell atlases in the post-genomic age.

Phasic firing in vasopressin cells: understanding its functional significance through computational models. [PDF]

PLoS Computational Biology, 2012
Vasopressin neurons, responding to input generated by osmotic pressure, use an intrinsic mechanism to shift from slow irregular firing to a distinct phasic pattern, consisting of long bursts and silences lasting tens of seconds.
