Hemianopia (partial or complete) Nervous System Diseases
Conditions
Interventions
The study is designed to present visual stimulus sequences that replicate a conventional visual search scanning with additional audio cues to simulate real-life environments and turn the task into a ‘

Age
18 Years to 100 Years
Inclusion criteria
Inclusion criteria: 1. Participants are required to be residual homonymous hemianopia (partial or complete following stroke. 2. Participants must have normal hearing and no speaking/communication difficulty. 3. Participants must speak English fluently - in order to understand all training and test instructions. 4. Participants must be 18 years or older. 5. Participants must be able to perform the behavioural tasks, for which training will be provided. 6. Participants must be sufficiently mobile to attend scanning at the imaging centre/LiMRIC
Exclusion criteria
Exclusion criteria: 1. Participant who cannot sign the consent form or cannot read the participants’ information sheet and consent form. 2. Participants who cannot perform the task (the screening takes place before participants are invited to join the study to ensure that, participants can perform the task and to exclude vulnerable adults). 3. MR exclusion criteria: Standard MR exclusion criteria will apply (e.g. claustrophobia (fear of tight spaces), cardiac pacemaker, metal in the eye, vascular clips, actual or possible pregnancy). 4. COVID-19 check: if the participant has any symptoms before the first visit to LiMRIC for the MRI scan and before the training starts (Cough, fever, loss or change in the smell or taste https://www.nhs.uk/conditions/coronavirus-covid-19/symptoms/#symptoms), there is a flexibility to delay the starting of study, but this delaying can not be offer after the study is started. they will be excluded. We will be followed the COVID-19 procedure for LiMRIC at the recruitment period.
