Somatostatin Inhibits Neurally Stimulated Pancreatic Secretion Indirectly

Pancreas, 1990
We studied the effect of a primed i.v. infusion of somatostatin (100 micrograms as a bolus, 0.5 micrograms x kg-1 x min-1) on pancreatic exocrine secretion in response to electrical stimulation of the vagus nerves and intra-arterial infusions of acetylcholine (0.5 mg x min-1) in anesthetized pigs (17-22 kg).

Neural Crest Cells from Dual SMAD Inhibition

Current Protocols in Stem Cell Biology, 2015
AbstractNeural crest (NC) cells are migratory multipotent progenitors that delaminate from the neural tube during embryonic development and give rise to various cell types in different organs. These cells are a transient embryonic cell population and therefore difficult to obtain from primary sources.

When inhibition not excitation synchronizes neural firing

Journal of Computational Neuroscience, 1994
Excitatory and inhibitory synaptic coupling can have counter-intuitive effects on the synchronization of neuronal firing. While it might appear that excitatory coupling would lead to synchronization, we show that frequently inhibition rather than excitation synchronizes firing.

Neural mechanisms of response inhibition

Current Opinion in Behavioral Sciences, 2015
Response inhibition is the most basic form of behavioral control, which can occur either proactively to anticipate known task requirements, or reactively in response to sudden changes in the environment. This review will highlight some of the recent progress that has been made in understanding the mechanisms of response inhibition.

Neural precursor cells inhibit multiple inflammatory signals

Molecular and Cellular Neuroscience, 2008
Intravenous neural precursor cell (NPCs) injection attenuates experimental autoimmune encephalomyelitis by reducing autoreactive T cell encephalitogenicity in lymph nodes in vivo. Here we examined NPC-lymphocyte interactions in vitro. NPCs inhibited the induction of T cell activation marker IL-2-Receptor alpha, ICOS, PD-1 and CTLA-4 and inhibited T ...

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.

Memristor-Based Neural Network Circuit of Associative Memory With Overshadowing and Emotion Congruent Effect

IEEE Transactions on Neural Networks and Learning Systems
Most memristor-based neural network circuits consider only a single pattern of overshadowing or emotion, but the relationship between overshadowing and emotion is ignored.

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 ...
