In studies aimed at delineating the nature of coherent electrical activity
in normal brain function, we previously identified both plane
(figure) and rotating waves in sensory areas of non-mammalian
cortex. We further examined the theoretical basis of such waves
in terms of networks of weakly coupled phase oscillators.
Future experiments will address macroscopic patterns of electrical
activity within trigeminal brainstem regions and sensorimotor
cortical regions that comprise the rat vibrissa system. These
experiments will make use of optical techniques in conjunction
with brainstem slice and multi-electrode recording techniques
in conjunction with behaving animals.
