GABA<inf>B</inf> receptors: modulation of thalamocortical dynamics and synaptic plasticity
2021, NeuroscienceCitation Excerpt :In vivo experiments also studied the functions of GABAB-R blockage on short-term synaptic plasticity. Jia and colleagues described the impact of the blockage of GABAB-Rs in the thalamocortical visual pathway (Jia et al., 2004). They did so by means of electrical stimulation in the dLGN and recordings in V1 before and after iontophoresis of 2-hydroxy-saclofen.
The influences of dark rearing on the transmission characteristics of layer II/III pyramidal cells during the critical period
2012, Brain ResearchCitation Excerpt :The reduction occurs mainly during P14 and P21, and dark rearing can retard this trend. Maturation of GABAergic inhibition is thought to be involved in the transformation of PPR of IPSCs in the visual cortex (Jia et al., 2004; Morales et al., 2002; Ramoa and Sur, 1996). The IPSC/EPSC ratio increases gradually with age during the critical period of visual development.

2009, NeuropharmacologyCitation Excerpt :Using an inter-pulse interval of 250 ms, we observed significant PPD at local synapses, with no such depression at lpcs synapses under our basal recording conditions. Importantly, the GABAB receptor antagonist SCH-50911 significantly reduced PPD at local synapses, suggesting that a significant portion of PPD at local synapses is dependent on GABAB autoreceptor activation, as observed at GABAergic synapses in many other brain regions (Jia et al., 2004; Kolaj et al., 2004; Pearce et al., 1995). Although we found no evidence of synaptic activation of GABAB autoreceptors at lpcs synapses, bath application of SCH-50911 did significantly potentiate the peak amplitude of the paired lpcs responses compared to baseline levels, similar to our previous findings with individually-evoked lpcs IPSCs.
Functional degradation of visual cortical cells in aged rats
2006, Brain ResearchCitation Excerpt :Intervals between pairs of stimuli were at least 30 s. Optimal stimulus intensity was determined by running a full input–output series at the beginning of recording, and a stimulation intensity yielding 50–60% of maximum was selected for the experiment. The PPD ratio was measured as the size of the second postsynaptic potential (PSP) amplitude relative to the first PSP amplitude with paired-pulse stimulation (Jia et al., 2004). Saline filled, glass recording electrodes (2–3 MΩ impedance) were used to record neuronal activity.
