Single channel EEG systems are very useful in EEG based applications where real time processing, low computational complexity and low cumbersomeness are critical constrains. These include brain-computer interface and biofeedback devices and also some clinical applications such as EEG recording on babies or Alzheimer’s disease recognition. In this paper we address the problem of eye blink artifa...

PURPOSE To evaluate spontaneous blink activity in the primary eye position in normal preschool children. METHODS Two hundred normal children aged 4 to 6 years were prospectively evaluated. They were digitally videotaped in a standard setting, taking the images on frontal and lateral plans, during the vigil state, in the primary eye position. The object of observation was located at the same l...

BACKGROUND The purpose of this study was to investigate the occurrence and duration of extended blinks ≥ 70 msec and their associated interblink intervals in normal subjects and in subjects with mild to moderate dry eye. METHODS This single-center, prospective, double-blind study included 11 subjects with dry eye and eight subjects with normal eyes. Extended blinks were defined as lid closure...

Eye movements that accompany a blink have been measured in human subjects by the use of a visual-persistence method. With straight-ahead binocular viewing, each eye typically rotates nasalward and downward 1-2 deg during the closing phase of a blink. These eye movements are more rapid than the lid movements as recorded by high-speed photography. In fact, the eyes have already completed their in...

This paper describes the relationship between visual attention and eye blink frequency. In an experiment, we prompted the activation of a subject’s visual attention and examined the influence of visual attention (as measured using electrodermal activity (EDA), which is meaningfully correlated with visual attention) on the subject’s eye blink frequency. Experimental results show that engagement ...

Contamination of eye movement and blink artifacts in Electroencephalogram (EEG) recording makes the analysis of EEG data more difficult and could result in mislead findings. Efficient removal of these artifacts from EEG data is an essential step in improving classification accuracy to develop the brain-computer interface (BCI). In this paper, we proposed an automatic framework based on independ...

The electrooculogram (EOG) of voluntary eye blinking is a distinguishable one among other eye blinking types such as spontaneous or reflexive blinking. In our study, we aimed to measure/detect the EOG of voluntary blinking during Echo Planar Imaging in the MR scanner. After the pulse artifact removal in the EOG signal, the waveform of EOG can clearly show voluntary eye blinking and this was equ...

Neuronal activity was recorded in the cerebellar interpositus nucleus in infant rats during classical conditioning of the eye-blink response. The percentage and amplitude of eye-blink conditioned responses increased as a function of postnatal age. Learning-specific neuronal activity in the cerebellum emerged ontogenetically in parallel with the eye-blink conditioned response. There were also ag...

The electrical signal emitted by the eyes movement produces a very strong artifact on EEG due to its close proximity sensors and abundance of occurrence. In context detecting eye blink artifacts in waveforms for further removal purification, multiple strategies where proposed literature. Most commonly applied methods require use large number electrodes, complex equipment sampling processing dat...

<span>The purpose of this research is to observe the effectiveness independent component analysis (ICA) method for denoising raw EEG signals based on word imagination, which will be used classification unspoken speech. The electroencephalogram (EEG) are that represent electrical activities human brain when someone doing activities, such as sleeping, thinking or other physical activities. ...
