“…The prolonged latency of approximately 12-33 msec noted between stimulus and EMG response is perhaps unsurprising given the range of trigeminofacial reflexes known-classically the R1 and R2 of the blink reflex. 1,7 It was clear in our subjects that these long latency responses were not the result of direct facial stimulation; the links between facial and trigeminal are well known. The basis of these brainstem reflexes has been discussed in detail by Cruccu et al 3 Of note is the observation in Case 3 of a reflex-type response recorded from electrodes inserted into the cricothyroid muscle through the platysma muscle.…”

Object The aim in this paper was to localize and detect incipient damage to the ophthalmic and maxillary branches of the trigeminal nerve during tumor surgery. Methods This was an observational study of patients with skull base, retroorbital, or cavernous sinus tumors warranting dissection toward the cavernous sinus at a university hospital. Stimuli were applied as normal during approach to the cavernous sinus to localize cranial nerves (CNs) III, IV, and VI. Recordings were also obtained from the facial muscles to localize CN VII. The trigeminofacial reflex was sought simply by observing a longer time base routinely. Results Clear facial electromyography responses were reproduced when stimuli were applied to the region of V1, V2, and V3. Response latency was increased compared with direct CN VII stimuli seen in some cases. Responses gave early warning of approach to these sensory trigeminal branches. Conclusions The authors submit this as a new technique, which may improve the chances of preserving trigeminal sensory branches during surgery in this region.

This paper presents the review on eye blink detection methods used for the purpose of physically challenged or people suffering from ALS, epilepsy like disease. Brain Computer Interface (BCI) is a methodology which bridges a way for communication with the objects using brain thoughts. This paper will introduce to the other methods of eye blink detection and also to the NeuroskyMindwave which is a revolutionary product to detect Electroencephalogram signal (EEG) which also detects blink of an eye. It gives a glimpse upon the limitations of previous approaches and advantages of proposed product. At the end it will also address the future work which we are doing using this hardware for people suffering from ALS and epilepsy.
