Intrinsic optical signal (IOS) imaging promises to be a noninvasive method for high-
resolution examination of retinal physiology, which can advance the study and diagnosis of …

We measured birefringence, 90 degree scattered light, and voltage sensitive dye changes
from lobster walking leg nerves. Systematic application of key chemical agents revealed …

Direct optical methods to stimulate and record neural activity provide artifact-free,
noninvasive, and noncontact neurophysiological procedures. For stimulation, focused mid …

The measurement of birefringence variations related to nerve activity is a promising label‐
free technique for sensing compound neural action potentials (CNAPs). While widely …

To identify the neural constituents responsible for generating polarized light changes, we
created spatially resolved movies of propagating action potentials from stimulated lobster …

Linear polarization intrinsic optical signal (LP-IOS) measurement can provide sensitive
detection of neural activities in stimulus-activated neural tissues. However, the LP-IOS …

Laser diodes (LD) are commonly used for optical neural recordings in chronically recorded
animals and humans, primarily due to their brightness and small size. However, noise …

Existing fiber optics (FOs)-based sensors, including mechanical deformation ones rely on
structures embedded along the length of the FO. In this paper, we introduce and evaluate …

Optical scattering techniques have the potential to provide noninvasive measurements of
neural activity with good spatial and temporal resolution. We used the lobster nerve as a …

Simultaneous high spatial and temporal resolution brain imaging is the ultimate goal for
many neurophysiological studies; however, no existing technique can provide all the …
