Neuronal hyperexcitability and epileptogenesis

“Epilepsy represents a condition in which abnormal neuronal discharges or the hyperexcitability of neurons occur with synchronicity, presenting a significant public health challenge.” (opens the source at this quote in a new tab)
“This transformation presupposes the hyperexcitability of neuron groups, which become prone to discharge abnormally” (opens the source at this quote in a new tab)

Epileptiform synchronization in focal epileptic disorders

“Intracellular recordings from neurons located in these foci demonstrated that interictal events were associated with paroxysmal depolarizing shifts (PDSs) of the neuron membrane potential causing bursts of action potential firing followed by a hyperpolarization” (opens the source at this quote in a new tab)
“These findings provide insights into the mechanisms of seizure initiation and maintenance, thus leading to the development of specific pharmacological treatments for focal epileptic disorders.” (opens the source at this quote in a new tab)

Excitatory signaling in temporal lobe seizure generation

“In contrast to NMDA receptors, which contribute but are not indispensable for seizure generation, AMPA receptors appear to be a key component to triggering seizures.” (opens the source at this quote in a new tab)

KV7 channels and the M-current in the control of neuronal excitability

“Neuronal Kv7 channels underlie a voltage-gated non-inactivating potassium current known as the M-current.” (opens the source at this quote in a new tab)
“Due to its particular characteristics, Kv7 channels show pronounced control over the excitability of neurons.” (opens the source at this quote in a new tab)
“Kv7 channels locate to key areas for the control of action potential initiation and propagation.” (opens the source at this quote in a new tab)
“Finally, we will discuss the contribution of altered Kv7 activity to pathologies such as epilepsy and cognitive deficits.” (opens the source at this quote in a new tab)
