A neuron’s molecular clock. NMDA timing shapes the flow of information

In the brain, what matters is not only whether a signal reaches a nerve cell, but also how long its chemical gate remains open. A team led by Dr Mehdi Borjkhani from the International Centre for Translational Eye Research (ICTER) has demonstrated in a computational model that both excessively fast and excessively slow NMDA-receptor deactivation […]

Magnesium guards vision. An ICTER model identifies a window for retinal protection

The cells that transmit visual information from the eye to the brain can die when they become overloaded with calcium. Scientists led by Dr Mehdi Borjkhani of ICTER have shown in a computational model that magnesium can curb this dangerous influx of calcium without shutting down visual signaling. However, this intervention must be carefully controlled; […]

A new way to examine the cornea. Nine points at once

Researchers at the International Centre for Translational Eye Research (ICTER) have developed a prototype imaging system that can simultaneously track the cornea’s mechanical response at nine locations. The technology marks an important step toward more accurate, non-contact assessment of corneal biomechanics and could improve early detection and monitoring of disorders such as keratoconus.

Seeing through optical noise: a sharper way to image the eye

Modern OCT devices can look inside the eye without a scalpel – but they do not always capture everything that matters. Some critical information is simply lost, blurred by scattered photons. The STOC-T technology, developed for years by Prof. Maciej Wojtkowski and his team at ICTER, aims to resolve this problem – not through post-processing, […]

Poland knows how to build lasers. The problem starts later

Polish scientists are creating world-class technologies. The problem is that they are much more often used abroad than on the Polish market. During the LASER-TECHNICA panel discussion, experts spoke plainly: Poland does not lack talent or laboratories. What it lacks is a system capable of turning good ideas into real products and large-scale orders.

How to see the invisible? The limits of two-photon vision

Near-infrared light is invisible to humans. And yet, under the right conditions, the human eye can perceive it. Researchers from the International Centre for Translational Eye Research (ICTER) have now shown that the efficiency of this phenomenon depends not only on the laser pulse itself, but also on two highly specific factors: the beam diameter […]
