Postsynaptic activity of inhibitory neurons evokes hemodynamic fMRI responses [PDF]
Functional MRI responses are localized to the synaptic sites of evoked inhibitory neurons, but it is unknown whether, or by what mechanisms, these neurons initiate functional hyperemia.

Imperfect space clamp permits electrotonic interactions between inhibitory and excitatory synaptic conductances, distorting voltage clamp recordings. [PDF]
The voltage clamp technique is frequently used to examine the strength and composition of synaptic input to neurons. Even accounting for imperfect voltage control of the entire cell membrane ("space clamp"), it is often assumed that currents measured at ...

Cortical PV and VIP interneurons similarly influence SST neuron output despite distinct unitary properties [PDF]
Somatostatin (SST) expressing cells are powerful inhibitors of excitatory pyramidal neurons. It has been shown that SST cells are targeted by other inhibitory interneurons, namely parvalbumin- (PV) and vasoactive intestinal polypeptide- (VIP) expressing ...

Characteristics of long-duration inhibitory postsynaptic potentials in rat neocortical neuronsin vitro [PDF]
The characteristics of long-duration inhibitory postsynaptic potentials (1-IPSPs) which are evoked in rat frontal neocortical neurons by local electrical stimulation were investigated with intracellular recordings from an in vitro slice preparation. Stimulation with suprathreshold intensities evoked 1-IPSPs with typical durations of 600-900 msec at ...

Spike-timing dependent plasticity in inhibitory circuits [PDF]
Inhibitory circuits in the brain rely on GABA-releasing interneurons. For long, inhibitory circuits were considered weakly plastic in the face of patterns of neuronal activity that trigger long-term changes in the synapses between excitatory principal ...

Melatonin suppresses abnormal hyperexcitability of hippocampal CA1 neurons in early-stage oxygen-glucose deprivation [PDF]
Excitotoxicity in the early stages of ischemia is a primary trigger of neuronal injury. Literature has indicated the potential neuroprotective effects of melatonin against ischemic hypoxic injury, but the direct electrophysiological mechanisms underlying

Visualization by high resolution immunoelectron microscopy of the transient receptor potential vanilloid-1 at inhibitory synapses of the mouse dentate gyrus. [PDF]
We have recently shown that the transient receptor potential vanilloid type 1 (TRPV1), a non-selective cation channel in the peripheral and central nervous system, is localized at postsynaptic sites of the excitatory perforant path synapses in the ...

Spiking Neural P Systems with Membrane Potentials, Inhibitory Rules, and Anti-Spikes
Spiking neural P systems (SN P systems for short) realize the high abstraction and simulation of the working mechanism of the human brain, and adopts spikes for information encoding and processing, which are regarded as one of the third-generation neural

Inhibitory postsynaptic actions of taurine, GABA and other amino acids on motoneurons of the isolated frog spinal cord [PDF]
The actions of glycine, GABA, α-alanine, β-alanine and taurine were studied by intracellular recordings from lumbar motoneurons of the isolated spinal cord of the frog.
