Complex events initiated by individual spikes in the human cerebral cortex.

open access: yesPLoS Biology, 2008
Synaptic interactions between neurons of the human cerebral cortex were not directly studied to date. We recorded the first dataset, to our knowledge, on the synaptic effect of identified human pyramidal cells on various types of postsynaptic neurons and

Essential Functions of the Transcription Factor Npas4 in Neural Circuit Development, Plasticity, and Diseases

open access: yesFrontiers in Neuroscience, 2020
Signaling from the synapse to nucleus is mediated by the integration and propagation of both membrane potential changes (postsynaptic potentials) and intracellular second messenger cascades.

Regulation of Irregular Neuronal Firing by Autaptic Transmission [PDF]

open access: yes, 2016
The importance of self-feedback autaptic transmission in modulating spike-time irregularity is still poorly understood. By using a biophysical model that incorporates autaptic coupling, we here show that self-innervation of neurons participates in the ...

Nanodiamonds-induced effects on neuronal firing of mouse hippocampal microcircuits [PDF]

open access: yesScientific Reports 8, 2221 (2018), 2018
Fluorescent nanodiamonds (FND) are carbon-based nanomaterials that can efficiently incorporate optically active photoluminescent centers such as the nitrogen-vacancy complex, thus making them promising candidates as optical biolabels and drug-delivery agents. FNDs exhibit bright fluorescence without photobleaching combined with high uptake rate and low

Information processing occurs via critical avalanches in a model of the primary visual cortex [PDF]

open access: yesJ. Phys.: Conf. Ser. 686 012008 (2016), 2015
We study a new biologically motivated model for the Macaque monkey primary visual cortex which presents power-law avalanches after a visual stimulus. The signal propagates through all the layers of the model via avalanches that depend on network structure and synaptic parameter.

Synaptic potentiation of dual‐component excitatory postsynaptic currents in the rat hippocampus. [PDF]

open access: yesThe Journal of Physiology, 1995
1. Whole‐cell patch‐clamp recording has been used to study tetanus‐induced synaptic potentiation of dual‐component excitatory postsynaptic currents (EPSCs) in the CA1 region of rat hippocampal slices, following blockade of GABAA and GABAB receptor‐mediated synaptic inhibition. 2.

Presynaptic actions of 4-Aminopyridine and γ-aminobutyric acid on rat sympathetic ganglia in vitro [PDF]

open access: yes, 1980
Responses to bath-applications of 4-aminopyridine (4-AP) and -aminobutyric acid (GABA) were recorded intracellularly from neurones in the rat isolated superior cervical ganglion.

Brain injury impairs working memory and prefrontal circuit function

open access: yesFrontiers in Neurology, 2015
More than 2.5 million Americans suffer a traumatic brain injury (TBI) each year. Even mild to moderate traumatic brain injury causes long-lasting neurological effects.

Exploring the role of NMDA receptor in memory

open access: yesGerman Journal of Pharmaceuticals and Biomaterials, 2023
N-Methyl-D-aspartate (NMDA), a receptor belonging to the family of ionotropic glutamate receptors (iGluRs), plays various physiological and pathological roles in the central nervous system (CNS).

A minimal model for synaptic integration in simple neurons [PDF]

open access: yesPhysica D 426 (2021) 132988, 2020
Synaptic integration is a prominent aspect of neuronal information processing. The detailed mechanisms that modulate synaptic inputs determine the computational properties of any given neuron. We study a simple model for the summation of excitatory inputs from synapses and illustrate its use by characterizing some functional properties of postsynaptic ...
