GABAergic signaling in the rat pineal gland
(Wiley Blackwell Publishing, Inc, 2016-08)
Pinealocytes secrete melatonin at night in response to norepinephrine released from sympathetic nerve terminals in the pineal gland. The gland also contains many other neurotransmitters whose cellular disposition, activity, ...
GABAergic signaling within the basolateral amygdala complex modulates resistance to the labilization/reconsolidation process
(Academic Press Inc Elsevier Science, 2017-10)
It is well known that stress can affect mnemonic processes. In particular, stress before contextual fear conditioning induces a memory which exhibits resistance to being interfered with by Midazolam (MDZ) when applied after ...
Inhibitory pathways and the inhibition of luteinizing hormone-releasing hormone release by alcohol
(National Academy of Sciences, 2000-02)
In this research we examined the mechanisms by which ethanol (EtOH) inhibits luteinizing hormone-releasing hormone (LHRH) release from incubated medial basal hypothalamic explants. EtOH (100 mM) stimulated the release of ...
Gabaergic control of anxiety-like behavior, but not food intake, induced by ghrelin in the intermediate medial mesopallium of the neonatal chick
(Academic Press Inc Elsevier Science, 2015-01)
Ghrelin (Grh) is an endogenous ligand of the growth hormone secretagogue receptor. In neonatal chicks, central Ghr induces anxiogenic-like behavior but strongly inhibits food intake. The intermediate medial mesopallium ...
Rapid actions of the neurosteroid allopregnanolone on ovarian and hypothalamic steroidogenesis: Central and peripheral modulation
(Wiley Blackwell Publishing, Inc, 2020-01)
The present study aimed to determine whether an i.c.v. administration of allopregnanolone (ALLO) rapidly modifies the hypothalamic and ovarian 3β‐hydroxysteroid dehydrogenase (3β‐HSD) enzymatic activity and gene expression ...
The anxiolytic effect of allopregnanolone is associated with gonadal hormonal status in female rats
(Elsevier Science, 2001-04)
The behavioural display in the plus-maze, an established experimental model of anxiety, was studied in rats injected into the lateral brain ventricle (i.c.v.) with the neurosteroid 3α-hydroxy-5α-pregnan-20-one (allopregnanolone). ...
Memory consolidation and reconsolidation in an invertebrate model: The role of the GABAergic system
(Pergamon-Elsevier Science Ltd, 2009-01)
Consolidation theory assumes that memories are labile during a limited time window after acquisition, but as time passes, memories become stable and resistant to amnesic agents. However, the vision of immutable memories ...
Prior stress promotes the generalization of contextual fear memories: Involvement of the gabaergic signaling within the basolateral amygdala complex
(Pergamon-Elsevier Science Ltd, 2018-04)
Fear generalization occurs when a response, previously acquired with a threatening stimulus, is transferred to a similar one. However, it could be maladaptive when stimuli that do not represent a real threat are appraised ...
Modulation of extrasynaptic GABAergic receptor activity influences glutamate release and neuronal survival following excitotoxic damage to mouse spinal cord neurons
(Pergamon-Elsevier Science Ltd, 2019-09)
Excitotoxic levels of released glutamate trigger a cascade of deleterious cellular events leading to delayed neuronal death. This phenomenon implies extensive dysregulation in the balance between network excitation and ...
Facilitated Glutamatergic Transmission in the Striatum of D 2 Dopamine Receptor-Deficient Mice
(American Physiological Society, 2001-02)
Dopamine (DA) receptors play an important role in the modulation of excitability and the responsiveness of neurons to activation of excitatory amino acid receptors in the striatum. In the present study, we utilized mice ...
