[HTML][HTML] Ion dynamics during seizures

JV Raimondo, RJ Burman, AA Katz… - Frontiers in cellular …, 2015 - frontiersin.org
Changes in membrane voltage brought about by ion fluxes through voltage and transmitter-gated
channels represent the basis of neural activity. As such, electrochemical gradients …

Why won't it stop? The dynamics of benzodiazepine resistance in status epilepticus

…, G Ramantani, CJ Akerman, JV Raimondo - Nature reviews …, 2022 - nature.com
Status epilepticus is a life-threatening neurological emergency that affects both adults and
children. Approximately 36% of episodes of status epilepticus do not respond to the current …

Neuronal chloride and excitability—the big impact of small changes

Optogenetic silencing strategies differ in their effects on inhibitory synaptic transmission

JV Raimondo, L Kay, TJ Ellender, CJ Akerman - Nature neuroscience, 2012 - nature.com
Optogenetic silencing using light-driven ion fluxes permits rapid and effective inhibition of
neural activity. Using rodent hippocampal neurons, we found that silencing activity with a …

Excitatory effects of parvalbumin-expressing interneurons maintain hippocampal epileptiform activity via synchronous afterdischarges

TJ Ellender, JV Raimondo, A Irkle… - Journal of …, 2014 - Soc Neuroscience
Epileptic seizures are characterized by periods of hypersynchronous, hyperexcitability
within brain networks. Most seizures involve two stages: an initial tonic phase, followed by a …

Excitatory GABAergic signalling is associated with benzodiazepine resistance in status epilepticus

…, CJ Akerman, AJ Trevelyan, JV Raimondo - Brain, 2019 - academic.oup.com
Status epilepticus is defined as a state of unrelenting seizure activity. Generalized convulsive
status epilepticus is associated with a rapidly rising mortality rate, and thus constitutes a …

Adenosine release during seizures attenuates GABAA receptor-mediated depolarization

A Ilie, JV Raimondo, CJ Akerman - Journal of Neuroscience, 2012 - Soc Neuroscience
Seizure-induced release of the neuromodulator adenosine is a potent endogenous
anticonvulsant mechanism, which limits the extension of seizures and mediates seizure arrest. For …

[HTML][HTML] A genetically-encoded chloride and pH sensor for dissociating ion dynamics in the nervous system

JV Raimondo, B Joyce, L Kay, T Schlagheck… - Frontiers in cellular …, 2013 - frontiersin.org
Within the nervous system, intracellular Cl − and pH regulate fundamental processes including
cell proliferation, metabolism, synaptic transmission, and network excitability. Cl − and pH …

[HTML][HTML] Short-term ionic plasticity at GABAergic synapses

JV Raimondo, H Markram, CJ Akerman - Frontiers in synaptic …, 2012 - frontiersin.org
Fast synaptic inhibition in the brain is mediated by the pre-synaptic release of the
neurotransmitter γ-Aminobutyric acid (GABA)and the post-synaptic activation of GABA-sensitive …

[PDF][PDF] A genetically targeted ion sensor reveals distinct seizure-related chloride and pH dynamics in GABAergic interneuron populations

A Călin, T Waseem, JV Raimondo, SE Newey… - Iscience, 2023 - cell.com
Intracellular chloride and pH play fundamental roles in determining a neuron's synaptic
inhibition and excitability. Yet it has been difficult to measure changes in these ions during …
