Welcome to The Brain Stimulation Lab @ HW

The lab is devoted to the study of body representation and disgust processing. 



“Neural basis and kinematic parameters of reaching and grasping”

The study aims at exploring the neural basis of the influence of the tactile versionof the RHI on hand movement’s parameters. By means of comparing kinematic parameters before and after a rubber hand illusion, we will be able to explore if the changes related to proprioception, in absence of vision, influence hand physical movements.

Investigator: Federico Brusa


“Body Ownership: comparison between lower and upper limbs ownership with the tactile version of the RHI and the RFI”

The study aims at exploring both behavioural parameters and the neural basis of the ubber limbs illusion, using tactile information only and focusing on the comparison of upper and lower body parts.

 Investigator: Federico Brusa


“Body Ownership: how the size of the limbs affects the body ownership?”

The study aims at continuing the adventure begun with the study “Body Ownership: comparison between lower and upper limbs ownership with the tactile version of the RHI and the RFI”. This time we aim at understanding the role of size: is bigger always better???

Enhancing memory binding abilities across age using tDCS”  Project funded by Alzheimer Scotland Action on Dementia. Project ended May 2019. Stay tuned for results!

Recent studies suggest that transcranial Direct Current Stimulation (tDCS) can enhance Visual Short term Memory (VSTM) capacity (Tseng et al., 2012). Binding is a cognitive construct that operates in VSTM but can be dissociated from other VSTM functions (Parra et al. 2014). Binding is vulnerable to abnormal variants of ageing such as Alzheimer’s disease and declines dramatically in older adults with cognitive impairment (e.g., MCI) who are at the highest risk of developing dementia (Koppara et al., 2015). Proving that binding functions can be enhanced using brain electrical stimulation would help design non-pharmacological interventions aimed at enhancing memory abilities relevant to everyday life functioning. To this aim, we will apply tDCS to a brain network pivotal for VSTM binding (Parra et al., 2014). Secondly, we will investigate the electrophysiological changes related to the stimulation and, finally, we will explore the impact of ageing on memory benefits drawn from tDCS.

Lost in BSL translation: Psychology meets BSL interpreters” Project funded by HWU Annual Fund Large Project Grants 2017 and 2018.

The aim of the project is to promote awareness of the needs of hearing impaired individuals in a health setting in both future psychologists and British Sign Language (BSL) interpreting and translation (I&T). The project will implement sessions in the form of formal training and role-plays, where professional psychologists and BSL interpreters, together with deaf individuals acting as patients, will actively interact with students in Psychology and in BSL I&T in a mock clinical setting. 


Body Representation in BSL
