did not affect ion selectivity and slowed its deactivation time course, resulting in a tail crossover phenomenon. Paroxetine inhibited Kv3.1 channels in a use-dependent manner. Taken together, these results suggest that paroxetine blocks the open state of Kv3.1 channels. Given the role of Kv3.1 in fast spiking of interneurons, our data imply that the blockade of Kv3.1 by paroxetine might elevate epileptic activity of neural networks by interfering with repetitive firing of inhibitory neurons. -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.5 10 555-563 (9 pages)
Electrical stimulation through retinal prosthesis elicits both short and long-latency retinal ganglion cell (RGC) spikes. Because the short-latency RGC spike is usually obscured by electrical stimulus artifact, it is very important to isolate spike from stimulus artifact. Previously, we showed that topographic prominence (TP) discriminator based algorithm is valid and useful for artifact subtraction. In this study, we compared the performance of forward backward (FB) filter only vs. TP-adopted... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2016, Vol.20 No.1 13 101-109 (9 pages)
Reducing [Mg2+]o to 0.1 mM can evoke repetitive [Ca2+]i spikes and seizure activity, which induces neuronal cell death in a process called excitotoxicity. We examined the issue of whether cultured rat hippocampal neurons preconditioned by a brief exposure to 0.1 mM [Mg2+]o are rendered resistant to excitotoxicity induced by a subsequent prolonged exposure and whether Ca2+ spikes are involved in this process. Preconditioning by an exposure to 0.1 mM [Mg2+]o for 5 min inhibited significantly... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2015, Vol.19 No.6 7 523-531 (9 pages)
Serotonin [5-hydroxytryptamine (5-HT)] regulates synaptic plasticity in the visual cortex. Although the effects of 5-HT on plasticity showed huge diversity depending on the ages of animals and species, it has been unclear how 5-HT can show such diverse effects. In the rat visual cortex, 5-HT suppressed long-term potentiation (LTP) at 5 weeks but enhanced LTP at 8 weeks. We speculated that this difference may originate from differential regulation of neurotransmission by 5-HT between the age... -
Phasic and Tonic Inhibition are Maintained Respectively by CaMKII and PKA in the Rat Visual Cortex

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2014, Vol.18 No.6 11 517-524 (8 pages)
Phasic and tonic γ-aminobutyric acidA (GABAA) receptor-mediated inhibition critically regulate neuronal information processing. As these two inhibitory modalities have distinctive features in their receptor composition, subcellular localization of receptors, and the timing of receptor activation, it has been thought that they might exert distinct roles, if not completely separable, in the regulation of neuronal function. Inhibition should be maintained and regulated depending on changes in... -

to induce long-term potentiation (LTP) in the STT neurons. Coincident stimulation of both pre- and postsynaptic neurons using TBS showed immediate and persistent increase in AMPA receptor-mediated EPSCs. LTP can also be induced by postsynaptic spiking together with pharmacological stimulation using chemical NMDA. TBS-induced LTP observed in STT neurons was blocked by internal BAPTA, or Ni2+, a T-type VOCC blocker. However, LTP was intact in the presence of L-type VOCC blocker. These results... -

Previously, we reported that besides retinal ganglion cell (RGC) spike, there is ∼10 Hz oscillatory rhythmic activity in local field potential (LFP) in retinal degeneration model, rd1 mice. The more recently identified rd10 mice have a later onset and slower rate of photoreceptor degeneration than the rd1 mice, providing more therapeutic potential. In this study, before adapting rd10 mice as a new animal model for our electrical stimulation study, we investigated electrical characteristics of... -

Gamma-aminobutyric acid (GABA)-ergic inhibition is important in the function of the visual cortex. In a previous study, we reported a developmental increase in GABAA receptor-mediated inhibition in the rat visual cortex from 3 to 5 weeks of age. Because this developmental increase is crucial to the regulation of the induction of long-term synaptic plasticity, in the present study we investigated in detail the postnatal development of phasic and tonic inhibition. The amplitude of phasic... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2010, Vol.14 No.5 14 337-343 (7 pages)
Long-term potentiation (LTP) and long-term depression (LTD) have both been studied as mechanisms of ocular dominance plasticity in the rat visual cortex. In a previous study, we suggested that a developmental increase in serotonin [5-hydroxytryptamine (5-HT)] might be involved in the decline of LTP, since 5-HT inhibited its induction. In the present study, to further understand the role of 5-HT in a developmental decrease in plasticity, we investigated the effect of 5-HT on the induction of LTD... -

HPLC를 이용한 축육(Pork Muscle)내의 Dihydrostreptomycin 검출법
조건하에서 실제시료인 고기에 표준 DST를 1ppm을 spiking한 후 SPE상에서 SCX(Strong cation exchange column)을 통한 clean-up과정을 거친 후의 DST의 limit of quantification(LOQ)는 약 0.47ppm이었으며, 이에 대한 회수율은 97.7%(n= 8)를 나타냈다. 실제 codex에서 권장한 고기의 MRL이 0.6ppm인 점을 감안하면 codex 권고치에 도달할 수 있는 것으로 판단되었다. 따라서 본 연구에서 개발된 시험법은 지금까지 국내적으로 DST에 대한 시험법이 확립되어 있지 않은 것으로 이와 아울러 간편한 parallux와 병용해 DST에 대한 정량 및... -

확산에 의한 소자 failure 등이 문제로 발생하게 되며, 또한 선폭이 줄어듦에 따라 고열이 발생하여 실리콘으로 spiking이 발생하게 된다. 이를 방지하기 위하여 본 논문에서는 질소와 탄소를 첨가한 3개의 화합물로 구성된 Tungsten-Carbon-Nitrogen (W-C-N) 확산방지막을 사용하였다. 실험은 물리적 기상 증착법(PVD)으로 질소비율을 변화하며 확산방지막을 증착하였고, 이를 여러 가지 온도에서 열처리하여 열적인 안정성에 대한 실험을 실시하였다. 결정구조를 확인하기 위하여 X-ray Diffraction 분석을 통하여 확산방지막의 특성을... -

동해 울릉분지에서 가스하이드레이트 탐사를 목적으로 획득된 탄성파 중합 자료에 다음 세 가지의 디컨볼루션을 적용하여 지층경계면을 분해하는 특성을 분석하였다: (1) 트레이스별 최소위상 스파이킹 디컨볼루션 (2) 트레이스 평균 최소위상 디컨볼루션 (3) 검층자료를 이용한 디컨볼루션. 트레이스별 최소위상 스파이킹 디컨볼루션의 경우 수직 분해능은 증가하지만 수평 연장성이 감소하는 경향을 보였다. 각 트레이스에서 구한 최소위상 파형요소를 평균하여 구한 대표 파형요소를 이용하는 두 번째 방법은 전체적으로 트레이스별... -
