Vision, Posture and Balance

RESEARCH STUDY

Vision, Posture and Balance Study (Optic Flow) – This study has now been completed

We asked – how good is your balance? Would you like to know your Falls Risk Score?

We asked for older adults to participate in this study looking at how vision influences posture and balance.

Participants were:

  • Aged 60 years and older
  • In fair to good health – good vision when wearing glasses, no neurological disorders
  • Able to stand for 60 seconds without a support

The aims of this study was to determine:

  1. 1. Whether balance, posture and standing body alignment and muscle activity are affected by vision differ between young and older people and between older people at low and high risk of falls
  2. 2. Whether an over-reliance on vision for balance control might increase the risk of falls

The study involved an assessment with a series of interesting tests evaluating your vision, strength, reaction time, sensation, balance and mobility.

All procedures are safe and are routinely used in clinical and research settings.

Study participants received an assessment report on their balance with recommendations for minimising the risk of falling.

The study was completed over a 2 hour session at Neuroscience Research Australia in Randwick, NSW.

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.
