Until I used the custom µECoG array, I never knew the precise extent of visually evoked activity, especially with this spatial and temporal resolution.

~Mr. Ingmar Schneider

The Laurent lab is interested in the behavior, dynamics and emergent properties of neural systems. Their efforts are focused on the cerebral cortex of turtles to facilitate the identification, mechanistic characterization and computational description of cortical functional principles. The aim of Ingmar’s work is to functionally characterize visually responsive areas in turtle dorsal cortex and to analyze their spatiotemporal dynamics in response to naturalistic visual stimulation. The size and flexible cabling of the µECoG array have been designed specifically to perform chronic recordings from the entire extent of dorsal cortex. Electrode density and package size have been carefully balanced to (i) achieve high electrode density (64 channels, pitch 500µm) and (ii) ensure connector compactness for chronic implantation, without restricting the animals’ natural behavior. These µECoG electrodes allow routine recording of spatiotemporal patterns of both stimulus-evoked and spontaneous oscillatory activity in chronically implanted turtles.

Results

Chronic experiments are currently underway.
