Horizontal Interactions in Cat Striate Cortex: III. Ectopic Receptive Fields and Transient Exuberance of Tangential Interactions.

The European journal of neuroscience

Luhmann HJ, Greuel JM, Singer W.
PMID: 12106043
Eur J Neurosci. 1990;2(4):369-377. doi: 10.1111/j.1460-9568.1990.tb00428.x.

In this study the developmental changes of intracortical connectivity are related to changes of cortical receptor fields (RFs). The RFs of striate cortex neurons of 4- to 8.5-week-old kittens, reared under normal conditions (NR) or in a selective visual...

Effects of chaotropic anions on bicuculline inhibition of high affinity ?-aminobutyric acid binding in bovine retina and rat brain membranes.

Neurochemistry international

Churchill L, Redburn DA.
PMID: 20487943
Neurochem Int. 1983;5(2):221-6. doi: 10.1016/0197-0186(83)90117-1.

Chaotropic anions (ions that favour transfer of apolar groups to water) increased bicuculline inhibition of (3)H-?-aminobutyric acid binding to bovine retinal membranes as previously reported for rat forebrain membranes. The increased bicuculline inhibition was reversible when the chaotropic anion...

Effect of bicuculline on the spontaneous and evoked activity of patterned embryonic hippocampal neurons cultured in vitro.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Khatami D, Nam Y, Brewer G, Wheeler B.
PMID: 17271191
Conf Proc IEEE Eng Med Biol Soc. 2004;2004:4059-62. doi: 10.1109/IEMBS.2004.1404133.

Characterization of the spontaneous and evoked activity of patterned biological neural networks and discovery of the underlying mechanisms is a major step towards designing functional networks for biosensor, biocomputing and neural prosthetic applications. Here we report on the addition...

Evaluation of GABA Receptors of Ventral Tegmental Area in Cardiovascular Responses in Rat.

Iranian journal of medical sciences

Rasoulpanah M, Kharazmi F, Hatam M.
PMID: 25031490
Iran J Med Sci. 2014 Jul;39(4):374-81.

BACKGROUND: The ventral tegmental area (VTA) is well known for its role in cardiovascular control. It is demonstrated that about 20-30% of the VTA neurons are GABAergic though their role in cardiovascular control is not yet understood. This study...

Inhibition of Gabrp reduces the differentiation of airway epithelial progenitor cells into goblet cells.

Experimental and therapeutic medicine

Wang A, Zhang Q, Wang Y, Li X, Li K, Li Y, Wang J, Li L, Chen H.
PMID: 34007329
Exp Ther Med. 2021 Jul;22(1):720. doi: 10.3892/etm.2021.10152. Epub 2021 May 03.

Bronchial asthma is an intractable pulmonary disease that affects millions of individuals worldwide, with the overproduction of mucus contributing to high morbidity and mortality. Gamma-aminobutyric acid (GABA) is associated with goblet cell hyperplasia in the lungs of primate models...

BICUCULLINE/BACLOFEN-INSENSITIVE GABA RESPONSE IN CRUSTACEAN NEURONES IN CULTURE.

The Journal of experimental biology

Jackel C, Krenz W, Nagy F.
PMID: 9317565
J Exp Biol. 1994 Jun;191(1):167-93.

Neurones were dissociated from thoracic ganglia of embryonic and adult lobsters and kept in primary culture. When gamma-aminobutyric acid (GABA) was applied by pressure ejection, depolarizing or hyperpolarizing responses were produced, depending on the membrane potential. They were accompanied...

Characterization of binding sites for [(3)H]Gaba in Drosophila melanogaster CNS membranes.

Neurochemistry international

Rosario P, Barat A, Ramirez G.
PMID: 20504472
Neurochem Int. 1989;15(1):115-20. doi: 10.1016/0197-0186(89)90083-1.

Drosophila melanogaster membranes prepared from cephalic ganglia contain two apparently independent populations of saturable binding sites for [(3)H]GABA: the higher-affinity sites (K(d) = 23 nM; B(max = 0.97 pmol/mg)) are already labeled at 0 degrees C, while a lower-affinity...

Dysregulation of GABAergic Signalling Contributes in the Pathogenesis of Diarrhea-predominant Irritable Bowel Syndrome.

Journal of neurogastroenterology and motility

Aggarwal S, Ahuja V, Paul J.
PMID: 29852727
J Neurogastroenterol Motil. 2018 Jul 30;24(3):422-430. doi: 10.5056/jnm17100.

BACKGROUND/AIMS: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a prevalent functional bowel disorder. Abdominal pain, discomfort and altered intestinal habits are the salient features of IBS-D. Low grade inflammation and altered neurotransmitters are the 2 recently identified factors contributing to...
