Mircea Steriade (August 20, 1924-April 14, 2006), MD, DSc, was a prominent researcher in systems neuroscience. He was born in Bucharest, Romania, and studied medicine at University of Bucharest. He emigrated to Canada in 1968, where he became a professor of physiology at Université Laval in Quebec, a position he held for the rest of his life.

The majority of his research was on corticothalamic oscillations. He was among the first to study the dynamics of the brain during sleep, and one of his key discoveries was determining the role of thalamic reticular neurons as pacemakers in producing the sleep spindle rhythm. He also discovered slow (<1 Hz) sleep rhythms associated with intracortical activity.

The correct functioning of the mammalian brain depends on the integrated activity of myriad neuronal and non-neuronal cells. Discrete areas serve discrete functions, and dispersed or distributed communities of cells serve others. Throughout, these networks of activity are under the control of neuromodulatory systems. One goal of current neuroscientific research is to elucidate the precise methods by which these systems operate, especially during normal conscious behaviours and processes. Mircea Steriade and Denis Pare describe the neuronal properties and networks that exist within and between the cortex and two important sub-cortical structures: the thalamus and amygdala. The authors explore the changes in these properties, covering topics including morphology, electrophysiology, architecture and gating; and comparing regions and systems in both normal and diseased states. Aimed at graduates and postdoctoral researchers in neuroscience.
