The Impact of Excitatory Coupling on Synchronous Activity of Neural Oscillator Population.
Although these symptoms have been shown to arise from neuronal hyperexcitability in the dorsal horn, resulting from enhanced excitatory amino acid (EAA) signaling [7, 8] and/or loss of central inhibition [9], the underlying mechanisms responsible for these sensory changes remain poorly understood.
There are two kinds of neurons in the network: excitatory and inhibitory neurons.
In the olfactory bulb, there is an interaction between excitatory MCs and inhibitory GCs.
The fluorescent markers did not affect the neuron's ability to function, allowing the scientists to see live excitatory and inhibitory synapses and how they change as new memories are formed.
Among specific topics are optogenetic strategies to dissect the neural circuits that underlie reward and addiction, the cocaine-evoked synaptic plasticity of excitatory transmission in the ventral tegmental area, glutamate mechanisms underlying opiate memories, translational research in nicotine dependence, and the opioid pharmacogenetics of alcohol addiction.
Using an animal model of depression, the work suggests that this common mental disorder actually may be caused by the abnormal transmission of excitatory signals between brain cells--signals that are vital to stimulating activity and responses among cells, suggests a study published in the March 17, 2013 issue of Nature Neuroscience.
Immunohistochemical markers were used to identify the new cells which included excitatory granule cells, astrocytes, and a very small number of the interneurons.
The effect of local functional heterogeneities which are considered crucial for the mechanisms of epilepsy [19] is investigated in a spatially extended neural mass formulation with local excitatory and inhibitory circuits [20].
Dr David Bailey, a GP in Trethomas and chair of the Welsh GP committee, said: "If, instead of taking in their calories from a proper breakfast, which has been shown to be beneficial in terms of health, children are taking stimulants, which have shown to be excitatory in young children, then that's probably not the best thing for school learning."
(3) Although the precise cause of these neuromuscular abnormalities has not been elucidated, one possible explanation is that they may be the result of neuronal injury mediated by excitatory amino acids.
PRP duration can index changes in the value of a reinforcing consequence; however, it can also reflect inhibitory postreinforcement effects and/or excitatory stimulus effects (Bonem & Crossman, 1988; Perone & Courtney, 1992; Schlinger, Derenne, & Baron, 2008).
