Rats received a single training trial on an inhibitory avoidance (passive avoidance) task and retention trials 24 hr (R-I) and 48 hr (R-II) later, in a special two-chambered apparatus, and the mean step-through latency was determined. The animals were given the drug, either pre-trial, pre-trial plus pre-retention, pre-retention or post-trial. Physostigmine (0.1 mg/kg, ip) and atropine (6.0 mg/k...

It has been shown that the stepping to recover balance following a forward fall occurs at a constant time (on average 293 ms) (Do et al. Journal of Biomechanics 15, 1982, 933-939). In this study, we tested the hypothesis according to which programming to make fast movement could trigger the movement earlier than when programming self-pace movement. The same experimental paradigm of forward fall...

Recent theories of visual attention, such as the oculomotor readiness theory of Klein (1980) (Does oculomotor readiness mediate cognitive control of the visual attention. In: R. Nickerson, Attention and performance, Hillsdale: Erlbaum), the premotor theory of Rizzolati (1983) (Mechanisms of selective attention in mammals. In: J.P. Ewart, R.R. Capranica, D.J. Ingle, Advances in vertebrate Neuroe...

The present study was conducted to evaluate the effect of 2-phenylethynyl-butyltellurium (PEBT), an organotellurium compound, at doses of 5 and 10 mg/kg on memory, employing the step-down inhibitory avoidance task in mice. Moreover, the involvement of glutamate uptake and release in cerebral cortex and hippocampus of mice was investigated. A single oral administration (p.o.) of PEBT at the dose...

We studied pursuit eye movements in seven normal human subjects with the scleral search-coil technique. The initial eye movements in response to unpredictable changes in target motion were analyzed to determine the effect of target velocity and position on the latency and acceleration of the response. By restricting our analysis to the presaccadic portion of the response we were able to elimina...

This paper proposes a short packet GFDM-based physical (PHY) layer for industrial wireless networks to reduce latency. In our proposed PHY layer, the conventional OFDM scheme used in data field of IEEE 802.11 WLAN standards is replaced by GFDM. The preamble size also reduced from 10 symbols 1 symbol. Furthermore, fields overall structure are optimized terms total number subcarriers and cyclic p...

objective(s):parkinson's disease (pd) is known for motor impairments. but often, there are non-motor symptoms such as cognitive deficiency and pain misperception, owing to possible role of nigrostriatal pathway. antioxidants have protective effect on free radical-induced neuronal damage in pd. to further address, we examined the effects of ellagic acid (ea) in a rat model of pd induced by ...

Abstract To reduce the background z -Vertex Track Trigger estimates collision origin in Belle II experiment using neural networks. The main part is a pre-trained multilayer perceptron. task of this perceptron to estimate -vertex suppress from outside interaction point. For this, low latency real-time FPGA implementation needed. We present an overview architecture and neuronal network preprocess...

introduction: the glutamatergic system plays an important role in learning and memory. administration of crocus sativus (saffron) or its constituent, crocin, facilitates the formation of memory. this research investigated the effect of crocin on antagonizing retrograde amnesia induced by ketamine, a glutamatergic receptor antagonist, in rats by shuttle box. methods:  male wistar rats were teste...
