ANALYSIS OF THE SLOW EXCITATORY POSTSYNAPTIC POTENTIAL IN BULLFROG SYMPATHETIC GANGLION CELLS

open access: bronzeThe Japanese Journal of Physiology, 1976
The ionic mechanism of the slow excitatory postsynaptic potential (slow EPSP), i.e. the muscarinic action of acetylcholine (ACh), was studied either by stimulating preganglionic nerves or by applying ACh in curarized sympathetic ganglion cells of bullfrogs.

Postsynaptic spiking determines anti-Hebbian LTD in visual cortex basket cells [PDF]

open access: yesFrontiers in Synaptic Neuroscience
Long-term plasticity at pyramidal cell to basket cell (PC → BC) synapses is important for the functioning of cortical microcircuits. It is well known that at neocortical PC → PC synapses, dendritic calcium (Ca2+) dynamics signal coincident pre-and ...

Effect of Background Synaptic Activity on Excitatory-Postsynaptic Potential-Spike Coupling

open access: bronze, 2003
Neurons receive large amount of synaptic inputs in vivo, which may impact the coupling between EPSPs and spikes. We mimicked the in vivo synaptic activity of the cell with the dynamic clamp system. We recorded from pyramidal cells in neocortical slices in vitro to investigate how timing and probability of spike generation in response to an EPSP is ...

Imperfect space clamp permits electrotonic interactions between inhibitory and excitatory synaptic conductances, distorting voltage clamp recordings. [PDF]

open access: yesPLoS ONE, 2011
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 ...

Impact of the activation rate of the hyperpolarization-activated current $I_{\rm h}$ on the neuronal membrane time constant and synaptic potential duration [PDF]

open access: yesEur. Phys. J. Spec. Top. (2021), 2021
The temporal dynamics of membrane voltage changes in neurons is controlled by ionic currents. These currents are characterized by two main properties: conductance and kinetics. The hyperpolarization-activated current ($I_{\rm h}$) strongly modulates subthreshold potential changes by shortening the excitatory postsynaptic potentials and decreasing their

Regulation of spike timing-dependent plasticity of olfactory inputs in mitral cells in the rat olfactory bulb. [PDF]

open access: yesPLoS ONE, 2012
The recent history of activity input onto granule cells (GCs) in the main olfactory bulb can affect the strength of lateral inhibition, which functions to generate contrast enhancement.
