After receiving of each input pattern network had an additional time for finishing of all transitional processes (refractory, learning, postsynaptic potential propagation).
8 mg (14 [micro]mol)/kg bw BDE-47 via a metal gastric tube on postnatal day (PND) 10 for field-excitatory postsynaptic potential (f-EPSP) recordings and brain protein analysis, or 68 mg (140 [micro]mol)/kg bw BDE-47 for amperometric recordings of chromaffin cells (to investigate presynaptic effects) at PND17-19.
The nAChR responds to neurotransmitter stimulation by allowing rapid influx of sodium, producing an excitatory postsynaptic potential.
First of all, it is necessary to match the data on the duration of inhibitory postsynaptic potentials (IPSP), ranging from milliseconds to tens of milliseconds, with the data on the duration of the internal inhibition process, ranging from several seconds to several minutes.
Halogenated aromatic hydrocarbons suppress CA1 field excitatory postsynaptic potentials in rat hippocampal slices.
As shown by Armitage and Siegelbaum (1998), short-term homosynaptic depression of the in vitro sensorimotor synapse proceeds normally with repeated activation of the sensory neuron despite a blockade of (presumably) postsynaptic glutamate receptors by DNQX sufficient to eliminate the sensorimotor excitatory postsynaptic potential (EPSP).
Relationship between presynaptic calcium current and postsynaptic potential in squid giant synapse.
EEG records cumulated excitatory and inhibitory postsynaptic potentials in neuronal dendrites, usually in the superficial cerebral cortex.
Methods: Field excitatory postsynaptic potentials (fEPSPs), spontaneous excitatory postsynaptic currents (sEPSCs) and miniature spontaneous excitatory postsynaptic currents (mEPSCs) were recorded, by using in vitro field potential electrophysiology and whole-cell patch clamp techniques in acute hippocampal slices from rats.
Calcium dynamics in single spines during coincident pre- and postsynaptic activity depend on relative timing of back-propagating action potentials and subthreshold excitatory postsynaptic potentials.
Therefore, in the present study we tested whether TDE can modulate dendritic field excitatory postsynaptic potentials (fEPSPs), which indicate the neuronal synaptic function, in Cornu Ammonis 1 (CA1) hippocampal slices of normal rats as found in current AChE-I drugs used for AD therapy.
