what about colours? A few weeks back I was at a wedding reception. The hall got suddenly dark, and a coloured strobe light started illuminating the dance floor. I watched guests getting up on their feet to dance with the newlywed couple. Bless them. But I started feeling stressed and uneasy in my head (not least because I did not join in – largely due to my lack of dancing faculty). But the rea...

In a series of 2053 cases of epilepsy studied 3.9% were found to have some form of photosensitive epilepsy. The mean age of onset was 14.9 years for males, 11.8 years for females. In the age group of 6-10 years there was a definite male preponderance. In 48.2% cases the seizures were caused by watching television and in 7.4% they were precipitated by sunlight or electric lights. Primary general...

A simple photosensitive method to assess movements of the whole body or its parts was described. The method was applied to record head movements to target sources of visual and auditory stimuli.

A photosensitive plate based on sintered TiO2 nanoparticles has been developed to carry out in-source photo-induced reductions for cleavage of disulfide bridges using glucose as a hole scavenger during laser desorption ionization.

Non-mammalian vertebrates have an intrinsically photosensitive iris and thus a local pupillary light reflex (PLR). In contrast, it is thought that the PLR in mammals generally requires neuronal circuitry connecting the eye and the brain. Here we report that an intrinsic component of the PLR is in fact widespread in nocturnal and crepuscular mammals. In mouse, this intrinsic PLR requires the vis...

While it was customary to express animal instincts in terms of human behavior, one of us many years ago began to replace this anthropomorphic. method by the objective and quantitative methods of the physicist. These methods were most easily applicable in the case of those instincts familiar to every layman in which animals were apparently attracted or repelled by light. Loeb1 was able to expres...

Photosensitive epilepsy (PSE) offers a highly reproducible model to investigate whether changes in neuronal activity preceding the transition to an epileptic photoparoxysmal response (PPR) may be detected. We investigated this possibility in patients with idiopathic PSE using MEG, as well as normal controls and non-photosensitive epileptic patients of the same age group. Spectral analysis of th...

Herein, we incorporate photosensitive ortho-Nitrobenzyl units into polyurethanes to achieve controllable photodegradability. We performed their photolysis in solution and thin films which can inform the design of degradable adhesives.

An extensive photosensitive-polyimide (PSPI)-based method for designing and fabricating various neural electrode architectures was developed. The method aims to broaden the design flexibility and expand the fabrication capability for neural electrodes to improve the quality of recorded signals and integrate other functions. After characterizing PSPI's properties for micromachining processes, we...

Gabapentin usually has a good safety profile with adequate tolerance. The incidence of adverse reactions in skin, hair and mucosa due to gabapentin is low. Here, we present a case of lichenoid photosensitive eruption due to application of gabapentin in exposed areas. A lichenoid eruption with skin lesions that are widespread distributed requires a drug history as well as stopping the consumptio...
