Neural network model of prepulse inhibition.

Behavioral Neuroscience, 2005
The authors introduce a real-time model of acoustic prepulse inhibition (PPI) and facilitation (PPF) in animals and humans. The model incorporates excitatory and facilitatory pathways activated by the positive value of changes in noise level in the environment and an inhibitory pathway activated by the absolute value of changes in noise level.

Learning in competitively inhibited neural nets

1990 IJCNN International Joint Conference on Neural Networks, 1990
The competitively inhibited neural network (CINN) is a competitive learning paradigm which is modeled by a collection of ordinary differential equations. A sliding threshold condition has been derived for determining the activity of a CINN neuron. This condition allows the development of a mathematical model for CINN learning.

Inhibition of cortical neural networks using infrared laser

Journal of Biophotonics, 2019
The aim of the present study is to optimize parameters for inhibiting neuronal activity safely and investigating thermal inhibition of rat cortex neural networks in vitro by continuous infrared (IR) laser. Rat cortex neurons were cultured on multi‐electrode arrays until neural networks were formed with spontaneous neural activity.

Presynaptic Inhibition and Neural Control

1997
Abstract This is a timely review of the mechanisms underlying the presynaptic control of synaptic transmission and the role they play in sensory and motor behavior. Early chapters offer a detailed account of the anatomy, biophysics, and physiology of synaptic transmission at the peripheral and central synapses, focusing on the ...

D609 inhibits the proliferation of neural progenitor cells

NeuroReport, 2010
We examined the effect of tricyclodecan-9-yl-xanthogenate (D609), a phosphatidylcholine-specific phospholipase C inhibitor, on the proliferation of adult neural progenitor cells in vitro. D609 (100 microM) decreased the proliferation of neural progenitor cells as measured by the proliferation assay, bromodeoxyuridine incorporation, and cell counting ...

The Neural Mechanisms of Behavioral Inhibition

2018
Unfamiliar people, places, and objects often elicit wariness and distress in behaviorally inhibited infants. As behaviorally inhibited infants mature through childhood and become adolescents, peer-based social situations become the driving source of this wariness.

Neural Systems Involved in Fear Inhibition: Extinction and Conditioned Inhibition

2000
“I can’t get the memories out of my mind! The images come flooding back in vivid detail, triggered by the most inconsequential things, like a door slamming or the smell of stir-fried pork. Last night, I went to bed, was having a good sleep for a change. Then in the early morning a storm-front passed through and there was a bolt of crackling thunder.

The neural substrates of latent inhibition

2002
In order to extend the application of the SLG model from the purely behavioral domain to the neurophysiological domain, we define a mapping function between psychological and neurophysiological spaces that establishes where psychological variables are represented in the brain.

Inhibition Nets and Artificial Neural Networks

2004
An artificial neural network (ANN) with a distinguished external input may be considered as a tuple 〈U, W, A, O, NET, ex〉 having the following properties (this is the definition stated by Nauck et al. [113], pp.19–24, where also a general overview of ANNs is to be found): 1. U is a finite and non-empty set of units 2. W : U × U → ℝ is
