Imaging cortical electrical stimulation in vivo: fast intrinsic optical signal versus voltage-sensitive dyes.
We applied high-temporal-resolution optical imaging utilizing both the fast intrinsic optical signal (fIOS) and voltage-sensitive dyes (VSDs) to observe the spatiotemporal characteristics of rat somatosensory cortex during electrical stimulation. We find that changes in both the fIOS and VSD signals occur rapidly (<30 ms) after the stimulus is applied, suggesting that both membrane depolarizati...
متن کاملUse of Voltage - Sensitive Dyes and Optical
-Understanding the spatio-temporal features of the information processing occurring in any complex neural structure requires the monitoring and analysis of the activity in populations of neurons. Electrophysiological and other mapping techniques have provided important insights into the function of neural circuits and neural populations in many systems. However, there remain limitations with th...
متن کاملA computational model of the signals in optical imaging with voltage-sensitive dyes
Optical imaging with voltage-sensitive dyes (VSD imaging) can record neural activity over an area of several square centimeters with high spatiotemporal resolution. The relative contributions of subthreshold and suprathreshold activity to the VSD signal are, however, poorly understood, making it difficult to interpret the imaging result. This paper shows how the activity in a computational mode...
متن کاملOptical Imaging of Neurons in the Crab Stomatogastric Ganglion with Voltage-sensitive Dyes
Voltage-sensitive dye imaging of neurons is a key methodology for the understanding of how neuronal networks are organised and how the simultaneous activity of participating neurons leads to the emergence of the integral functionality of the network. Here we present the methodology of application of this technique to identified pattern generating neurons in the crab stomatogastric ganglion. We ...
متن کاملOptical signals from neurons with internally applied voltage-sensitive dyes.
We carried out experiments to monitor optically the generation and spread of action potentials and subthreshold potentials in the processes of individual neurons in ganglia of the snail, Helix aspersa. The neurons were selectively stained by intracellular pressure injection of voltage-sensitive dyes. Optical signals were detected by a system for fast, multiple-site optical monitoring, utilizing...
