Figure S1. Immunostaining of K 2P channels in the EC. A, Immunoractivities detected by the second set of K 2P ABs (Santa Cruz Biotechnology Inc.). Upper panels, low magnification; Low panels, high magnification of the regions denoted in the upper panels. The catalog numbers of the ABs were labeled on the top. B, Preabsorption of the first set of K 2P ABs(More)
The entorhinal cortex (EC) is regarded as the gateway to the hippocampus and thus is essential for learning and memory. Whereas the EC expresses a high density of GABA(B) receptors, the functions of these receptors in this region remain unexplored. Here, we examined the effects of GABA(B) receptor activation on neuronal excitability in the EC and spatial(More)
Whereas the entorhinal cortex (EC) receives profuse cholinergic innervations from the basal forebrain and activation of cholinergic receptors has been shown to modulate the activities of the principal neurons and promote the intrinsic oscillations in the EC, the effects of cholinergic receptor activation on GABAergic transmission in this brain region have(More)
To assess the actions of thiopental at the spinal dorsal horn level, we examined the effects of thiopental using the whole cell patch-clamp technique on mechanically dissociated rat spinal dorsal horn neurons. Thiopental, at large concentrations, elicited a current (I(Thio)) through activation of chloride conductance, and its threshold concentration was(More)
Neurotensin (NT) is a tridecapeptide distributed in the CNS, including the entorhinal cortex (EC), a structure that is crucial for learning and memory and undergoes the earliest pathological alterations in Alzheimer's disease (AD). Whereas NT has been implicated in modulating cognition, the cellular and molecular mechanisms by which NT modifies cognitive(More)
The entorhinal cortex is closely associated with the consolidation and recall of memories, Alzheimer disease, schizophrenia, and temporal lobe epilepsy. Norepinephrine is a neurotransmitter that plays a significant role in these physiological functions and neurological diseases. Whereas the entorhinal cortex receives profuse noradrenergic innervations from(More)
Whereas the ionotropic glutamate receptors are the major mediator in glutamatergic transmission, the metabotropic glutamate receptors (mGluRs) usually play a modulatory role. Whereas the entorhinal cortex (EC) is an essential structure involved in the generation and propagation of epilepsy, the roles and mechanisms of mGluRs in epilepsy in the EC have not(More)
Whereas corticotropin-releasing factor (CRF) has been considered as the most potent epileptogenic neuropeptide in the brain, its action site and underlying mechanisms in epilepsy have not been determined. Here, we found that the entorhinal cortex (EC) expresses high level of CRF and CRF2 receptors without expression of CRF1 receptors. Bath application of(More)
29 Whereas the entorhinal cortex (EC) receives profuse cholinergic innervations from the 30 basal forebrain and activation of cholinergic receptors has been shown to modulate the 31 activities of the principal neurons and promote the intrinsic oscillations in the EC, the 32 effects of cholinergic receptor activation on GABAergic transmission in this brain(More)
General anesthetics thiopental and pentobarbital possess very similar chemical structures whereas their clinical potency is quite different. The underlying molecular mechanism is not fully understood. This study was designed to assess the differential effects of thiopental and pentobarbital on GABA(A) receptors of mechanically dissociated rat spinal dorsal(More)
