Research Interests
1. Subcortical regulation of forebrain activity in the sleep-wake cycle. The central focus of my research is the subcortical regulation of hippocampal function and is guided by the general hypothesis that the role of this regulation is to build dynamic associations between several limbic structures that are synchronized by oscillatory population activity. Phasic and rhythmic synchronization of neuronal activity is critical to control the concerted action of spatially separated structures in the brain. The general state and background activity of various brain structures determine how these structures will respond to different specific inputs and how they establish dynamical connections to perform complex functions. An important constituent of these states is the pattern of population activity including coherent oscillations in anatomically scattered structures which can establish functional networks during specific behaviors. Theta synchrony provides an excellent model to study these cooperations and the way in which they differ in specific behavioral states, such as waking exploration and REM sleep.
2. Oscillatory processes in cardiovascular control. Another model we use to study rhythmic synchronization among neural networks is the autonomic nervous system which is capable of generating different patterns of activity that control the response of the cardiovascular system to changes in the environment (e.g. chemoregulation, thermoregulation, etc.) and different behavioral states (e.g. defense reaction, eating, sleep, etc.). Our guiding hypothesis in this research is that sympathetic rhythm is generated by multiple oscillators and we study the changes in the relationship between these oscillators under different conditions of health and disease.
