… A new brain imaging technique, the event-related optical signal (EROS), combines spatial …
The imaging signal reflects changes in the optical scattering properties of brain tissue that are …

… Studies have been performed with and without contrast agents (extrinsic versus intrinsic
optical signals). Optical signals have been used to map brain function after surgical exposure of …

… -invasive measurement of brain function, the event-related optical signal (EROS). This
technique is based on measures of the optical properties of cortical brain tissue, which change …

… the use of fast optical signals, and in … optical signals (EROS) (see Materials and Methods)
and review the evidence in favor and against the non-invasive recording of fast optical signals …

… In the remainder of this chapter, we review the main principles of optical imaging and some
of the types of optical signals that can be used to study brain function, as well as aspects of …

… These in vivo results confirm earlier findings obtained in brain slices that also showed a
strict dependence of somatic Ca 2+ signals on action potential firing (Fig. 5c; [36]). Thus, it …

… Our understanding of human brain function can clearly … that noninvasive nearinfrared optical
imaging methods can provide … human brain function based on electrophysiological signals, …

… review we focus only on the non-invasive methods that use near infrared light to probe
functional activity in the brain, namely the fast optical signal, diffuse correlation spectroscopy, and …

… changes in the human brain were carried out in this laboratory [1] where fast Fourier
transformation (FFT) of the optical signal in the frequency domain afforded adequate signal-to-noise …

… We first introduce four techniques for detecting intrinsic neural signals which come from
the change of their nature optical properties. We also explore the techniques for extrinsic …
