Assessment of brain haemodynamic responses using optical topography modality

Neuroimaging studies have shown that negative mood states will impair the working memory (WM) functions that affect haemodynamic conditions at the prefrontal cortex (PFC) region. Compared to other neuroimaging tools, haemodynamic responses in surrounding brain surfaces can be assessed feasibly and w...
