Subsequent behavioural studies revealed that some people with hemispatial neglect can also suffer from impaired spatial working memory,[17] often revisiting locations without being aware that they have fixated them before.
[30][31] Instead, this research revealed that although short-term memory is a highly limited resource, it can be flexibly deployed depending upon task demands.
[34] Work from Husain's lab showed that lesions to ventral basal ganglia leads to a condition of profound apathy, manifest as a lack of motivation to initiate action and specifically attributable to a deficit in reward sensitivity.
[39][40] This has led to a theoretical framework to understand mechanisms underlying apathy across brain disorders which incorporates concepts from cost-benefit decision making to formalise how people differ in their willingness to engage in effort in order to obtain potential rewards.
[46][47] A key component of voluntary control paradoxically appears to involve inhibition of unwanted actions that are primed automatically by seeing objects around us.
