background & purpose: a stroke occurs when blood flow to a region of the brain is interrupted by the blockage or rupturing of a blood vessel or artery. the most prevalent cause of aphasia is stroke. a brain damage that can effect on receptive & expressive language skills is aphasia. intensive language therapy is the most effective means of treating aphasia. the ciat is one of the novel intensiv...

The present study is an attempt to shed light on the effect of Dynamic Assessment (DA) on diagnosing and developing the receptive vocabulary abilities of upper-intermediate learners learning English as a foreign language. Fifty L2 leaners participated in the First Certificate in English test and completed Vocabulary Knowledge Scale. Out of 50 students, ten learners who were identified as being ...

The highly specific relationships between parallel fiber (PF) and climbing fiber (CF) receptive fields in Purkinje cells and interneurons suggest that normal PF receptive fields are established by CF-specific plasticity. To test this idea, we used PF stimulation that was either paired or unpaired with CF activity. Conspicuously, unpaired PF stimulation that induced long-lasting, very large incr...

We studied the effects of various patterns as contextual stimuli on human orientation discrimination, and on responses of neurons in V1 of alert monkeys. When a target line is presented along with various contextual stimuli (masks), human orientation discrimination is impaired. For most V1 neurons, responses elicited by a line in the receptive field (RF) center are suppressed by these contextua...

Natural scenes contain richer perceptual information in their spatial phase structure than their amplitudes. Modeling phase structure of natural scenes may explain higher-order structure inherent to the natural scenes, which is neglected in most classical models of redundancy reduction. Only recently, a few models have represented images using a complex form of receptive fields (RFs) and analyz...

Psychophysical and neurophysiological studies indicate that during the preparation of saccades, visual processing at the target location is facilitated automatically by the deployment of attention. It has been assumed that the neural mechanisms involved in presaccadic shifts of attention are purely spatial in nature. Saccade preparation modulates the visual responses of neurons within extrastri...

When a neuron could be recorded stably for sufficient time we verified our hand-plotted estimates of receptive field location using an automated stimulus presentation/response collation system (see Supplementary Methods online). As illustrated by the examples shown in Supplementary Figure 1, the two methods of estimating receptive field location show a close correspondence. We measured the disc...

This study aimed at investigating the effects of English as foreign language proficiency onlexical attrition of Iranian learners in Nouroz holidays. For this purpose, 90 students studiedEnglish translation at Qazvin Azad University were selected. They were sophomore and wereaccessible for the present study. After administering a proficiency test (OPT), 60 students wereselected according to the ...

The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Implantation of the embryo, can only take place in a receptive uterus and inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. Endometrial receptivity can be reduced by morphological and/or molec...

Under stimulation of the receptive fields (RF) of neurons in the cat area 17 by flashing Y-like figures of different shape and orientation, the sensitivity to these figures was revealed in 72% of the studied cells, while 62% of units were sensitive to cross-like figures as well. Tuning to Y-like figures was typically selective to their shape and orientation, but in some cases it was invariant t...
