Contrasting roles of axonal (pyramidal cell) and dendritic (interneuron) electrical coupling in the generation of neuronal network oscillations [PDF]
, 2003 Electrical coupling between pyramidal cell axons, and between interneuron dendrites, have both been described in the hippocampus. What are the functional roles of the two types of coupling?

Early neuronal accumulation of DNA double strand breaks in Alzheimer's disease. [PDF]
, 2019 The maintenance of genomic integrity is essential for normal cellular functions. However, it is difficult to maintain over a lifetime in postmitotic cells such as neurons, in which DNA damage increases with age and is exacerbated by multiple neurological

Distinct Subunit Domains Govern Synaptic Stability and Specificity of the Kainate Receptor
Cell Reports, 2016 Synaptic communication between neurons requires the precise localization of neurotransmitter receptors to the correct synapse type. Kainate-type glutamate receptors restrict synaptic localization that is determined by the afferent presynaptic connection.

Structural basis of kainate subtype glutamate receptor desensitization
Nature, 2016 Glutamate receptors are ligand-gated tetrameric ion channels that mediate synaptic transmission in the central nervous system. They are instrumental in vertebrate cognition and their dysfunction underlies diverse diseases.

Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]
, 2011 Adaptive forms of synaptic plasticity that reduce excitatory synaptic transmission in response to prolonged increases in neuronal activity may prevent runaway positive feedback in neuronal circuits.

Neurobiology of Disease, 1994 A minority subset of cortical neurones exhibit kainate-activated Co2+uptake, a marker for AMPA/kainate receptor gated Ca2+-permeable channels. Consistent with enhanced Ca2+influx through these channels, Co2+-positive neurones are unusually vulnerable to ...

Rapamycin attenuates acute seizure-induced astrocyte injury in mice in vivo [PDF]
, 2017 Astrocytes have been implicated in epileptogenesis and seizure-induced brain injury. Pathological studies reveal a variety of structural abnormalities in astrocytes, such as vacuolization and astrogliosis.

Cooperative Glutamatergic and Cholinergic Mechanisms Generate Short-Term Modifications of Synaptic Effectiveness in Prepositus Hypoglossi Neurons [PDF]
, 2005 To maintain horizontal eye position on a visual target after a saccade, extraocular motoneurons need a persistent (tonic) neural activity, called "eye-position signal," generated by prepositus hypoglossi (PH) neurons.

PLoS ONE, 2015 The C57BL/6J mouse as a model of seizure/epilepsy is challenging due to high mortality and huge variability in response to kainate. We have recently demonstrated that repeated administration of a low dose of kainate by intraperitoneal route can induce ...

Kainate receptor modulation by NETO2
Nature, 2021 Glutamate-gated kainate receptors (KARs) are ubiquitous in the central nervous system of vertebrates, mediate synaptic transmission on post-synapse, and modulate transmitter release on pre-synapse. In the brain, the trafficking, gating kinetics, and pharmacology of KARs are tightly regulated by Neuropilin and tolloid-like proteins (Netos).
