1. This signal can be either excitatory or inhibitory.

2. Quantal analysis of excitatory synapses in the hippocampus has proved difficult and has led to contradictory conclusions when applied to long-term potentiation.

3. He then varied the ratio of excitatory to inhibitory interaction strengths.

4. Do etal measured increases in excitatory aminoacids by push-pull cannulation in anesthetised human beings undergoing electrical stimulation.

5. Cowan suggests that the strength of the excitatory interactions increases relative to that of the inhibitory interactions under the influence of the drug.

6. Excitatory effects of somatostatin or octreotide on the sphincter of Oddi may impair biliary and pancreatic duct outflow.

7. Nothing happens until the excitatory stimulus exceeds a certain'threshold'value.

8. AMPA receptors mediate the fast excitatory synaptic transmission in the central nervous system.

9. Glutamatergic synapses are common excitatory chemical connections in mammalian central nervous system.

10. Objective To investigate manifestations of the plasmic excitatory amino acids in the patients with hemorrhagic cerebrovascular diseases.

11. No case with central excitatory phenomena was found in each group.

12. The excitatory effect of lidocaine can not be changed by pretreatment of hexamethonium bromide and atropine.

13. The excitatory effect of lidocaine can not be changed by pretreatment of hexamethonium bromide and at...

14. The characteristics of efferent terminal neurons eliciting excitatory and inhibitory responses were studied pharmaco- logically.

15. Spiking activity can induce persistent modification of excitatory synapses in cortical circuits.

16. Nodes on different levels which are mutually consistent have excitatory connections between them.

17. Although such inhibition might seem counterproductive,(http://Sentencedict.com) it is actually crucial. Normal brain function depends on both excitatory and inhibitory neurotransmitters.

18. And so it produces an inhibitory postsynaptic potential that subtracts from the excitatory ones.

19. The effect of the inhibitory zone is subtracted from the output from the excitatory region.

20. Like the skin comparison neurons in the spinal cord, the center may be excitatory and the surround inhibitory.

21. The cortical response induced by application of TRH both topical and intravenous would be converted into excitatory response when topical pre-treatment with 1-2 % GABA.

22. Urethane has a wide spectrum of effects and affects both inhibitory and excitatory ligand - gated channels.

23. It is suggested that Li's No.5 could antagonize the neurotoxicity excitatory amino acid.

24. Results Atro-pine, diethylamine methyl ester hydrochloride and tetrodotoxin could abolish the excitatory role of somatostatin on the sphincter.

25. Results Both the high and low dose BSXN abated excitatory toxic infury and inhibit neurocyte apoptosis after ischemia- refusion .

26. The increased ion concentration generates a negative potential, preventing the cell from being able to produce an excitatory electrical pulse.

27. The responses of respiration to hypoxia is , that is respiratory excitatory at first, then respiratory depression.

28. OBJECTIVE To observe the effect of electrical acupuncture on long-term potentiation (LTP) of excitatory postsynaptic potential (EPSP) of normal rats and rats with hypomnesia induced by scopolamine.

29. The results showed that as a neurotransmitter TRH has facilitatory effect on excitatory synaptic transmission in spinal cord.

30. The results suggest that the PAG may exert an excitatory influence on pontine micturition reflex of the rat.
