Recently, the self has become an important focus of conscious mind research. Neuroimaging studies reveal that the self emerges from the spontaneous activity of cortical midline structures (CMS). Prefrontal cortex structures are also mentioned prominently in consciousness theories such as higher-order and global workspace theories. This preliminary study aims to observe changes in frontal hemodynamics in response to self-related and non-self-related stimuli. The study included five healthy voluntary participants (mean age=25.6±5.986). Auditory stimuli containing the subject's own name (SON) wer

In order to assess the recovery of neural activity after stroke, it is necessary to select tasks that can be performed in the early stages of recovery. Since hand flexion is the first functional recovery that can be observed, it is a promising task to evaluate the recovery process. fMRI has reported that the amplitude of neural activity varies with the intensity of movement, but the correlation between movement and neural activity itself has not been reported in functional near-infrared spectroscopy (fNIRS). To investigate this, the present study performed simultaneous fMRI and fNIRS measureme

Spatial frequency domain imaging (SFDI) is a diffuse optical measurement technique that can quantify tissue optical absorption and reduced scattering on a pixel by-pixel basis. Measurements of absorption at different wavelengths enable the extraction of molar concentrations of tissue chromophores over a wide field, providing a noncontact and label-free means to assess tissue viability, oxygenation, microarchitecture, and molecular content. In this talk, I will describe openSFDI, an open-source guide for building a low-cost, small-footprint, multi-wavelength SFDI system capable of quantifying a
