Contrast enhancement plays a key role in analyzing medical images taken through different diagnosing methods (like CT scan, X-ray and MRI) especially in biomedical applications and secures digital image transmission. The principle objective of image enhancement technique is to improve the characteristics or quality of an input image. To improve the image contrast, numerous enhancement technique...

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....

context the current study aimed to review research articles concerning cortical representational plasticity following the manipulations of inputs. evidence acquisition this review article compromised previous studies in pubmed, google scholar and scientific information databases according to the keywords since 1988. results ca1 neurons depolarization paired with ca3 presynaptic input result in ...

One key theme in sociological analysis of neuro-enhancement has been the question of whether the drive for enhancement promotes the cultural value of individualism. It has been argued that neuro-enhancement discourses implicitly propagate new responsibilities that oblige individuals to continually “work on” their brain to ensure its health and productivity. However, much of this critique relies...

Extracellular recordings were conducted in the paraflocculus of anesthetized Long-Evans pigmented rats to determine how ionotophoresis of norepinephrine (NE) affects the responsiveness of individual Purkinje cells and interneurons to presentations of visual stimuli within their visual receptive fields. Presentations of moving or stationary visual stimuli during the control (pre-NE) period elici...

Neuroimaging work on multisensory conflict suggests that the relevant modality receives enhanced processing in the face of incongruency. However, the degree of stimulus processing in the irrelevant modality and the temporal cascade of the attentional modulations in either the relevant or irrelevant modalities are unknown. Here, we employed an audiovisual conflict paradigm with a sensory probe i...

Visual perception changes as a function of hand proximity. While various theoretical accounts have been offered for this alteration (attentional prioritisation, bimodal cell involvement, detailed evaluation, and magnocellular neuron input enhancement), the current literature lacks consensus on these mechanisms. The purpose of this review, therefore, is to critically review the existing body of ...

Normal-hearing (NH) adults display audiovisual enhancement when degraded auditory input (e.g., words, sentences) is paired with point -light displays (PLDs) of speech, which isolate the kinematic properties of a speaker’s face [10]. Do deaf adults who use cochlear implants (CIs) benefit in the same way? Does feedback influence NH adults’ performance? In the present study, we investigated audiov...

What is the role of top-down attentional modulation in consciously accessing working memory (WM) content? In influential WM models, information can exist in different states, determined by allocation of attention; placing the original memory representation in the center of focused attention gives rise to conscious access. Here we discuss various lines of evidence indicating that such attentiona...
