Streptozotocin Inhibits Electrophysiological Determinants of Excitatory and Inhibitory Synaptic Transmission in CA1 Pyramidal Neurons of Rat Hippocampal Slices: Reduction of These Effects by Edaravone

open access: yesCellular Physiology and Biochemistry, 2016
Background: Streptozotocin (STZ) has served as an agent to generate an Alzheimer's disease (AD) model in rats, while edaravone (EDA), a novel free radical scavenger, has recently emerged as an effective treatment for use in vivo and vitro AD models ...

Population rate coding in recurrent neuronal networks with undetermined-type neurons [PDF]

open access: yesarXiv, 2019
Neural coding is a key problem in neuroscience, which can promote people's understanding of the mechanism that brain processes information. Among the classical theories of neural coding, the population rate coding has been studied widely in many works.

Synaptic Plasticity and Excitation-Inhibition Balance in the Dentate Gyrus: Insights from In Vivo Recordings in Neuroligin-1, Neuroligin-2, and Collybistin Knockouts

open access: yesNeural Plasticity, 2018
The hippocampal dentate gyrus plays a role in spatial learning and memory and is thought to encode differences between similar environments. The integrity of excitatory and inhibitory transmission and a fine balance between them is essential for ...

Unsupervised learning by a nonlinear network with Hebbian excitatory and anti-Hebbian inhibitory neurons [PDF]

open access: yesarXiv, 2018
This paper introduces a rate-based nonlinear neural network in which excitatory (E) neurons receive feedforward excitation from sensory (S) neurons, and inhibit each other through disynaptic pathways mediated by inhibitory (I) interneurons. Correlation-based plasticity of disynaptic inhibition serves to incompletely decorrelate E neuron activity ...

Simulation α of EEG using brain network model [PDF]

open access: yes, 2017
In this paper, we developed a large-scale brain network model comprising of four cerebral areas in the left hemisphere, and each area is modelled as an oscillator Jansen and Rit (JR) model.

Measuring synaptic transmission and plasticity with fEPSP recordings in behaving mice

open access: yesSTAR Protocols, 2022
Summary: Spontaneous spiking activity depends on intrinsic excitability and synaptic input. Historically, synaptic activity has been mostly studied ex vivo.

In Vivo Monosynaptic Excitatory Transmission between Layer 2 Cortical Pyramidal Neurons

open access: yesCell Reports, 2015
Little is known about the properties of monosynaptic connections between identified neurons in vivo. We made multiple (two to four) two-photon targeted whole-cell recordings from neighboring layer 2 mouse somatosensory barrel cortex pyramidal neurons in ...

Neural computation at the thermal limit [PDF]

open access: yesarXiv, 2014
Although several measurements and analyses support the idea that the brain is energy-optimized, there is one disturbing, contradictory observation: In theory, computation limited by thermal noise can occur as cheaply as ~$2.9\cdot 10^{-21}$ joules per bit (kTln2).

Effect of endogenous substance P on visceral afferent signal integration in the nucleus tractus solitaries of rat brainstem slices

open access: yesIBRO Neuroscience Reports, 2023
In the first synapse of the blood-pressure-regulating pathway, a neurokinin (NK) family peptide substance P (SP) is release with an excitatory neurotransmitter, glutamate, to enhance the sensitivity of the baroreflex responses.

Framework of consciousness from semblance of activity at functionally LINKed postsynaptic membranes

open access: yesFrontiers in Psychology, 2010
Consciousness is seen as a difficult binding problem. Binding, a process wheredifferent sensations evoked by an item are associated in the nervous system, can beviewed as a process similar to associative learning.
