Altered Corticobrainstem Connectivity during Spontaneous Fluctuations in Pain Intensity in Painful Trigeminal Neuropathy
A new publication led by Luke Henderson and Noemi Meylakh at NeuRA Imaging reveals cortical systems underlying changes in perceived pain in painful trigeminal neuropathy. Pain perception is vital to survival, warning us of danger and motivating us to remove ourselves from it. It is adaptive and transient. However, in some cases, pain persists beyond …
Ethanol reduces brain electrical tissue conductivity in social drinkers in a region-specific pattern
A new publication led by Lindy Rae and Jun Cao at NeuRA Imaging shines light on the effect of alcohol on brain conductivity in social drinkers. Ethanol has two main effects on the brain. It acts as a stimulant at very low concentrations but is also a sedative, substantially reducing brain metabolism, particularly through activity …
Unravelling the Mystery of Sleep Apnoea: How Dynamic MRI Helps Decode Tongue Muscle Behaviour
Have you ever wondered why some people experience interrupted breathing during sleep? It turns out that the way our tongue muscles behave during sleep plays a crucial role, and researchers at NeuRA are using dynamic MRI techniques to uncover the secrets behind this phenomenon. A recent study by a team of scientists at Neuroscience Research …
RESEARCH SPOTLIGHT: Needles in a haystack – searching for a consistent placebo analgesia responder
We know that many people can experience placebo analgesia – but are these responses stable over time? Borrowing from the designs of longitudinal preclinical investigations, researchers at NeuRA, led by Professors Luke Henderson and Kevin Keay, have recently completed preliminary data collection investigating the consistency of placebo analgesia, combining genetic, behavioural, biological, and brain imaging …
RESEARCH SPOTLIGHT: Using Magnetic Resonance Elastography (MRE) To Define The Shear Properties Of Fat Under Load
We know that you have heard of MRI, but have you heard of MRE? Magnetic resonance elastography, or MRE as it is commonly known as, is an emerging MR technique that allows the stiffness of internal tissues to be measured quickly and noninvasively. Researchers at NeuRA, led by Professor Lynne Bilston, have recently published a …
RESEARCH SPOTLIGHT Using MRI to acquire fast, repeatable brain conductivity measurements
Recent advancements in an imaging technique that measures tissue conductivity and permittivity have positioned it to be a potential candidate for use in many future MRI research studies. Implementation of MREPT in the clinic requires repeatable measurements at a short scan time and an appropriate protocol. Here, we investigated the repeatability of conductivity measurements using …
