Real-time full field laser Doppler imaging

Theo Lasser, Marcel Leutenegger, Antonio Lopez, Tyler Nerton Thacher, Erica Martin-Williams

We present a full field laser Doppler imaging instrument, which enables real-time in vivo assessment of blood flow in dermal tissue and skin. This instrument monitors the blood perfusion in an area of about 50 cm² with 480 × 480 pixels per frame at a rate ...

Post-Surgical Interval And Lesion Location Within The Limbic Thalamus Determine Extent Of Retrosplenial Cortex Immediate-Early Gene Hypoactivity

Guillaume Poirier

Four experiments examined the disruptive effects of selective lesions in limbic thalamic nuclei on retrosplenial cortex function, as characterized by striking changes in immediate-early gene activity. Major goals were to test the specificity of these retro ...
