Receptive fields in primary visual cortex have been shown to be capable of rapid expansion and contraction when exposed to an artificial scotoma, a masked segment of the visual field. To distinguish cortical from thalamic contributions to receptive field mutability, we tested interocular transfer of the effect in binocular cortical receptive fields, presenting the conditioning stimulus to the f...

Visual receptive fields of superior colliculus neurons were investigated. The latencies of "on" and "off" responses were measured and their distribution all over the field was mapped. In 36 percent of the receptive fields the latency of the "off" response was shorter than the latency of the "on" response; 19 percent of the receptive fields had almost equal latencies; in 13 percent the latency o...

The response properties and receptive field organization of 106 LSA neurons were investigated in pretrigeminal preparations using moving dark and bright stimuli with particular reference to the dynamic and static structure of receptive fields. About 61percent neurons revealed equal sensitivity to the motions of dark and bright stimuli. A majority of them had an ON-OFF static structure of recept...

The fine structure of the receptive fields of the lateral suprasylvian area neurons was investigated in the pretrigeminal cat preparation. A majority of the receptive fields consisted of subregions with different qualitative characteristics according to their response to moving visual stimuli. There was an asymmetry in the spatial distribution of inhibitory mechanisms over the receptive field. ...

Our study investigated how attention paid to a target syntactic construction causative had is related the storage capacity and attention regulation function of working memory (WM) and how these WM abilities moderate the change of knowledge of the target construction in different input conditions. 80 Sri Lankan learners of English were exposed to examples of the target construction in explicit a...

This study investigated the family reading behavior of 233 preschool children from low-income backgrounds who were attending Head Start. Parents completed a survey of their family reading behavior, including Child Reading, Parent Reading Interest, and Parent–Child Reading Interaction, and provided demographic data on their educational level, parent and child age, and family size. Children’s rec...

BACKGROUND Considerable cardiovascular disease and cancer risk among firefighters are attributable to excess adiposity. Robust evidence confirms strong relationships between dietary patterns and the risk of chronic disease. Dietary modification is more likely to be effective when the strategy is appealing and addresses knowledge gaps. OBJECTIVE To assess career firefighters' diet practices an...

In macaque ventral premotor cortex, we recorded the activity of neurons that responded to both visual and tactile stimuli. For these bimodal cells, the visual receptive field extended from the tactile receptive field into the adjacent space. Their tactile receptive fields were organized topographically, with the arms represented medially, the face represented in the middle, and the inside of th...

Information is integrated across the visual field to transform local features into a global percept. We now know that V1 neurons provide more spatial integration than originally thought due to the existence of their nonclassical inhibitory surrounds. To understand spatial integration in the visual cortex, we have studied the nature and extent of center and surround influences on neuronal respon...

A fundamental concept in neuroscience is the receptive field, the area of space over which a neuron gathers information. Until about 25 years ago, visual receptive fields were thought to be determined entirely by the pattern of retinal inputs, so it was quite surprising to find neurons in primate cortex with receptive fields that changed position every time a saccade was executed [1]. Although ...
