Studies in both humans and monkeys have indicated that blinks affect the central programming of saccades. In this study, we compared the influence of two types of reflex blinks on the trajectories and kinematics of memory-guided saccades in human subjects. We found that electrical stimulation of the supraorbital nerve shortly before or during a saccade briefly halts or decelerates the eye in mi...

Blinking of eye is a routine human activity which seldom attracts any attention of clinicians in health and disease. There is experimental evidence that blink rate is affected in extrapyramidal disorders affecting the balance of these neurotransmitters. However, no observations regarding blink rate in Wilson disease (WD) have been reported previously. We report a patient of WD with an increased...

objective: this study aimed to examine the effects of haloperidol and amphetamine on human startle response modulated by emotionally-toned film clips. method: sixty participants, in two groups (one receiving haloperidol and the other receiving amphetamine) were tested using electromyography (emg) to measure eye-blink muscle (orbicular oculi) while different emotions were induced by six 2-minute...

Epilepsy is one of the most common neurological disorders characterized by transient and unexpected electrical disturbance of the brain. The electroencephalogram (EEG) is an important measurement for the purpose of assessing brain activities. It is a very effective tool for understanding the complex dynamical behaviour of the brain. The EEG based Brain Computer Interface (BCI) system is an effe...

Video game play induces a generalized recovery of a range of spatial visual functions in the amblyopic brain. Here we ask whether video game play also alters temporal processing in the amblyopic brain. When visual targets are presented in rapid succession, correct identification of the first target (T1) can interfere with identification of the second (T2). This is known as the "attentional blin...
