Proprioceptive deficits in Essential Tremor



Proprioceptive deficits in Essential Tremor

We are seeking volunteers who suffer from essential tremor, as well as healthy individuals who will serve as a control group. The study aims to understand how essential tremor influences the ability to use sensory information about the body, and how these problems may limit function. Testing will take ~2 hours.

The study might be a good fit for you if:


  • You are aged 18 years or older.


  • You have been diagnosed with essential tremor, or you think you may have essential tremor.


  • You have no history of neurological or orthopaedic problems affecting your arms and hands.


If you decide to take part you would be assessed on your ability to:

  • Perform tests of arm and hand function.
  • Answer questionnaires on arm and hand function.

You will be offered $20 per hour as remuneration for your time.

Caress the Detail: A Comprehensive MRI Atlas of the in Vivo Human Brain

This project aims to deliver the most comprehensive, detailed and stereotaxically accurate MRI atlas of the canonical human brain. In human neuroscience, researchers and clinicians almost always investigate images obtained from living individuals. Yet, there is no satisfactory MRI atlas of the human brain in vivo or post-mortem. There are some population-based atlases, which valiantly solve a number of problems, but they fail to address major needs. Most problematically, they segment only a small number of brain structures, typically about 50, and they are of limited value for the interpretation of a single subject/patient. In contrast to population-based approaches, the present project will investigate normal, living subjects in detail. We aim to define approximately 800 structures, as in the histological atlas of Mai, Majtanik and Paxinos (2016), and, thus, provide a “gold standard” for science and clinical practice. We will do this by obtaining high-resolution MRI at 3T and 7T of twelve subjects through a collaboration with Markus Barth from the Centre for Advanced Imaging at the University of Queensland (UQ). The limited number of subjects will allow us to image each for longer periods, obtaining higher resolution and contrast, and to invest the required time to produce unprecedented detail in segmentation. We will produce an electronic atlas for interpreting MR images, both as a tablet application and as an online web service. The tablet application will provide a convenient and powerful exegesis of brain anatomy for researchers and clinicians. The open access web service will additionally provide images, segmentation and anatomical templates to be used with most common MR-analysis packages (e.g., SPM, FSL, MINC, BrainVoyager). This will be hosted in collaboration with UQ, supporting and complementing their population-based atlas.
