Vestibular-evoked postsynaptic potentials in Deiters neurones

Experimental Brain Research, 1969
Stimulation of the vestibular nerve induced EPSPs monosynaptically in 29% of cat's Deiters neurones sampled on the ipsilateral side. These EPSPs started with latencies of 0.6–1.0 msec, rose sharply with a summit time of 0.5 msec and decayed exponentially with a time constant of 0.9–1.7 msec. Then amplitudes were graded finely according to the intensity

Postsynaptic potentials of bulbar respiratory neurons of the turtle

Respiration Physiology, 1986
Membrane potentials of bulbar respiratory neurons of Pseudemys scripta were recorded from unanesthetized, decerebrate animals. Efferent neurograms were recorded from the serratus magnus (inspiratory) and pectoralis (expiratory) nerves. The animals were paralyzed and ventilated by a servo-respirator driven by the pectoralis neurogram to mimic the ...

Postsynaptic Mechanisms Involved in Long-Term Potentiation

1990
Long-term potentiation (LTP) is a persistent enhancement of synaptic transmission observed at excitatory synapses in the mammalian hippocampus (Bliss and Lomo, 1973). This phenomenon is one of the most striking examples of synaptic plasticity in the vertebrate brain, and has been intensively studied as a model for learning and memory.

Inhibitory postsynaptic potentials of hypoglossal motoneurons of the cat

Experimental Neurology, 1972
Abstract The hypoglossal nerve of the cat contains some afferent fibers, but the role of these afferents in controlling hypoglossal motoneuron activity has not yet been analyzed. The effect of hypoglossal nerve stimulation on activity of hypoglossal motoneurons was investigated using microelectrode technique.

Block of glutamate transporters potentiates postsynaptic excitation

Neuron, 1994
We have studied the effects of blockers of glutamate transporters on excitatory synaptic transmission to determine whether transporters increase the clearance rate of transmitter from the synaptic cleft on the millisecond time scale. The transporter blockers Li+ and THA increased the amplitude, but not the decay time, of spontaneous miniature AMPA ...

Postsynaptic Membrane Fusion and Long-Term Potentiation

Science, 1998
The possibility that membrane fusion events in the postsynaptic cell may be required for the change in synaptic strength resulting from long-term potentiation (LTP) was examined. Introducing substances into the postsynaptic cell that block membrane fusion at a number of different steps reduced LTP.

Postsynaptic potentials in cat visual cortex

NeuroReport, 1992
During the investigation of visually evoked postsynaptic potentials (PSPs) of visual cortical neurons, we recorded cell activity under different levels of membrane potential. In some cases, however, dependence of these PSPs on the level of membrane polarization appears to be inconsistent with the conventional scheme. One disagreement was the reduction,

Stretch-evoked excitatory postsynaptic potentials in motoneurons

Brain Research, 1971
Abstract The profile of excitatory postsynaptic potential (EPSP) produced on triceps surae motoneurons by 5 msec duration triangular wave stretch of de-efferented medial gastrocnemius (MG) and soleus (S) muscles was observed on anesthetized, spinalized cats.

Intracellular Postsynaptic Potentials in the Somatosensory Cortex of the Cat

Nature, 1965
CELLULAR activity in the somatosensory cerebral cortex has been investigated in detail with extracellular recording. Excitatory phenomena have dominated the findings in these experiments although inhibitory actions, mostly as ‘surround inhibition’, have been reported1–3.

Tetanus-induced potentiation of inhibitory postsynaptic potentials in hippooampal CA1 neurons

Canadian Journal of Physiology and Pharmacology, 1995
In the present study, tetanus-induced potentiation of inhibitory postsynaptic potentials (IPSPs), previously described by our laboratory, was further investigated in guinea pig hippocampal CA1 neurons. Tetanic stimulation of the stratum radiatum induced a long-term potentiation of the excitatory postsynaptic potential and a potentiation of the γ ...
