A, the time-course of the averaged response of mIPSCs recorded with a high-[Cl−] internal solution and in the presence of TTX (1 μm) in a P12 and a P18 gerbil. The decay time-course was estimated by fitting a single exponential function to the response (broken line). B, the mean τdecay of mIPSCs at P12 (n = 11) and at P17–P20 (n = 20) and eIPSCs at P12 (n = 5) and at P17–P20 (n = 30). C, the corresponding mean 10–90% rise time of eIPSCs and mIPSCs at the same ages. A minimal <t>stimulation</t> protocol was used in the P12 animals. D, example of a single evoked IPSC response at P12. Note the inflection (arrow) on the rise of the event. Error bars represent 95% confidence intervals. The stimulus artefact has been deleted. *P < 0.05, **P < 0.01, ***P < 0.001.
Stimulation of the gustatory thalamus evokes time-varying PSP in GC neurons. A , Representative cresyl violet-stained coronal section showing the electrolytic lesion made by the tip of the <t>stimulating</t> electrode in VPMpc (arrow). VPMpc, ventroposteriomedial, parvocellular thalamus; VPM, ventroposteriomedial thalamus; VPL, ventroposteriolateral thalamus; VM, ventromedial thalamus; ZI, zona incerta; PH, posterior hypothalamus. B , Representative trace of a multi-unit response to the application of cold 0.3 M NaCl to the oral cavity as recorded by the VPMpc stimulating electrode. For each animal, the final DV coordinate of the VPMpc electrode was determined by where the greatest response to tasting solution was found. In this example, the depth was −6.5 mm from the pial surface. C , Representative synaptic response of a GC neuron to VPMpc stimulation at resting membrane potential, −77 mV. EPSP amplitude increases with intensity, resulting in an action potential at the greatest intensity. Inset, Mean ± SEM population intensity/response curve, normalized within each cell ( n = 14). y -axis: normalized PSP amplitude; x -axis: normalized stimulation intensity. D , Example trace of a cell responding to VPMpc stimulation with a monosynaptic EPSP followed by multi-synaptic inhibition, unveiled by stimulating with constant intensity at multiple holding potentials ( n = 5/10). Shaded lines indicate the times post-PSP onset where amplitudes were measured for determining the reversal potential of the components of the PSP: open circle, 3–5 ms post-onset; black triangle, 35 ms post-onset. E , Example trace of a cell responding to VPMpc stimulation with a monosynaptic EPSP followed by an upstate ( n = 5/10). No inhibition could be unveiled by depolarizing holding potentials. Shaded line with open circle indicates amplitude was measured 3–5 ms post-PSP onset for determining reversal potential. F , Population plot of reversal potentials for early component of PSP (open circles: 3–5 ms post-onset; n = 10) and late component (black triangles: 35 ms post-onset; n = 5). Reversal potentials were calculated by linear regression, represented by the lines on the graph. y -axis: normalized PSP amplitude; x -axis: holding potential (mV).

Replacing e37a- Cacna1b mRNA by e37b-Cacna1b results in enhanced probability of transmitter release in mPP-DG synapses. a Schematic describing approximate placement of recording (rec) and <t>stimulation</t> (stim) electrodes in the superior blade of DG and s.r. in CA1. b I/O relationships of fEPSPs from mPP-DG synapses recorded in WT and e37b-only mice. Slopes of fEPSPs were plotted as a function of the stimulus intensity. c I/O of fEPSPs from SC-CA1 synapses recorded in WT and e37b-only mice. Slopes of fEPSPs were plotted as a function of the stimulus intensity. d Representative traces of mPP-DG fEPSPs using a PPR protocol in WT and e37b-only slices ( left panel ). PPR of fEPSPs recorded at varying pulse intervals in slices of WT and e37b-only ( right panel ). e Representative traces of SC-CA1 fEPSPs using a PPR protocol in WT and e37b-only slices ( left panel ). PPR of fEPSPs recorded at varying pulse intervals in slices of WT and e37b-only mice ( right panel ). b-e . Data are shown as mean ± SE
Activation of D 2 autoreceptors during train pulse- but not single pulse-evoked DA overflow . A) The graphs represent the average amplitude and kinetics of train-evoked DA overflow in the presence of 5 μM sulpiride (left) or 1 μM quinpirole (right). B) Graph showing the effect of the D 2 receptor agonist quinpirole (1 μM; n = 3), and the D 2 receptor antagonist sulpiride (5 μM; n = 8) on DA overflow following pulse-train <t>stimulation.</t> Activation of D 2 receptors by quinpirole inhibits peak DA overflow, whereas the blockade of these receptors by sulpiride considerably enhances it. C) Graph comparing the effect of quinpirole (1 μM; n = 5), and sulpiride (5 μM; n = 4) on DA overflow evoked by single-pulse stimulation. Under these conditions, D 2 receptor activation also inhibits DA overflow, but D 2 receptor blockade has no effect.
