Laminar evoked responses in mouse somatosensory cortex suggest a special role for deep layers in cortical complexity by Hönigsperger, Christoph, Storm, Johan F., Arena, Alessandro

BK potassium channels facilitate high-frequency firing and cause early spike frequency adaptation in rat CA1 hippocampal pyramidal cells by Gu, Ning, Vervaeke, Koen, Storm, Johan F.

“…Neuronal potassium (K + ) channels are usually regarded as largely inhibitory, i.e. reducing excitability. Here we show that BK-type calcium-activated K +…”

Synergy of Glutamatergic and Cholinergic Modulation Induces Plateau Potentials in Hippocampal OLM Interneurons by Hagger-Vaughan, Nicholas, Storm, Johan F.

“…Oriens-lacunosum moleculare (OLM) cells are hippocampal inhibitory interneurons that are implicated in regulation of information flow in the CA1 circuit. OLM…”

Are we really unconscious in "unconscious" states? Common assumptions revisited by Sevenius Nilsen, Andre, Juel, Bjørn E, Thürer, Benjamin, Aamodt, Arnfinn, Storm, Johan F

“…In the field of consciousness science, there is a tradition to categorize certain states such as slow-wave non-REM sleep and deep general anesthesia as…”

Kv7/KCNQ/M and HCN/h, but not KCa2/SK channels, contribute to the somatic medium after-hyperpolarization and excitability control in CA1 hippocampal pyramidal cells by Gu, Ning, Vervaeke, Koen, Hu, Hua, Storm, Johan F.

“…In hippocampal pyramidal cells, a single action potential (AP) or a burst of APs is followed by a medium afterhyperpolarization (mAHP, lasting ∼0.1 s). The…”

Apical Function in Neocortical Pyramidal Cells: A Common Pathway by Which General Anesthetics Can Affect Mental State by Phillips, William A, Bachmann, Talis, Storm, Johan F

“…It has been argued that general anesthetics suppress the level of consciousness, or the contents of consciousness, or both. The distinction between level and…”
