One of the key factors for successful embryo implantation is the presence of a receptive endometrium. The achievement of a receptive endometrium involves proliferation and thickening of the endometrium, synchronization of the micro architectural changes of the endometrium with the stage of embryo development and the presence of a proper cytokine environment [1]. Despite its complexity, the proc...

The spatial receptive fields of neurons in medial entorhinal cortex layer II (MECII) and in the hippocampus suggest general and environment-specific maps of space, respectively. However, the relationship between these receptive fields remains unclear. We reversibly manipulated the activity of MECII neurons via chemogenetic receptors and compared the changes in downstream hippocampal place cells...

In their natural environment, animals experience a complex and dynamic visual scenery. Under such natural stimulus conditions, neurons in the visual cortex employ a spatially and temporally sparse code. For the input scenario of natural still images, previous work demonstrated that unsupervised feature learning combined with the constraint of sparse coding can predict physiologically measured r...

Neurophysiological mapping was used to study the effects of early postnatal removal of mystacial whiskers on the organization of cutaneous receptive fields (RFs) within the ventral posterior thalamus (VP) of rats. This sensory deprivation induced an extensive reorganization of the thalamus, as reflected in larger facial or continuous overlapping face-body RFs and a higher proportion of slowly-a...

background: aggressive embryo and receptive endometrium are necessary for successful implantation. on this time endometrium transformates to receptive state, which permits embryonic implantation. studies about embryonic implantation and endometrial receptivity are always a hot spot in the field of reproductive medicine. objective: to investigate the expression pattern of meis1 during peri-impla...

Even if a stimulus pattern moves at a constant velocity across the receptive field of motion-sensitive neurons, such as lobula plate tangential cells (LPTCs) of flies, the response amplitude modulates over time. The amplitude of these response modulations is related to local pattern properties of the moving retinal image. On the one hand, pattern-dependent response modulations have previously b...

To extract important information from the environment on a useful timescale, the visual system must be able to adapt rapidly to constantly changing scenes. This requires dynamic control of visual resolution, possibly at the level of the responses of single neurons. Individual cells in the visual cortex respond to light stimuli on particular locations (receptive ®elds) on the retina, and the str...

Home literacy environment (HLE) refers to a variety of resources and opportunities provided children as well the parental skills, abilities, dispositions, that determine provision such for children. For more than half century, large body studies have shown HLE can significantly promote children’s receptive vocabulary development. However, blurry operationalization HLE’s construct incon...

The purpose of the present study was to provide empirical support for the construct of the involvement load hypothesis (ILH ) in an EFL context. To fulfill the purpose of the study, 4 intact groups consisting of 126 intermediate-level students participated in this experiment. In order to ensure that the participants were at the same level of English language proficiency, the Nelson test was adm...

This study investigated the receptive and productive vocabulary command of learners based on their willingness to communicate (WTC) and critical thinking skill. The study also aimed to compare gifted and non-gifted learners in terms of the above-mentioned variables. To this end, 112 gifted and non-gifted Iranian EFL learners were picked out and given four instruments (W...
