One
of the least understood aspects of autonomic neurobiology concerns the
central mechanisms responsible for the control of sympathetic nerve discharges.
There is considerable data supporting the view that disturbances in control
of autonomic nerve activity can contribute to the development or maintenance
of hypertension, cardiac dysrhythmias, and other cardiovascular diseases.
Recent work demonstrates that different rhythms are evident in sympathetic
nerve activity depending upon the experimental conditions. The major objectives
of the research in our laboratories are
- to determine
which regions of the brain contain the neurons responsible for the
different rhythms in sympathetic activity
- to identify
the interconnections of single neurons with activity correlated to
sympathetic nerve activity
- to determine
what role the different rhythms play in regulating vasomotor tone
and in mediating complex and highly differentiated cardiovascular
response patterns as occur during defense,exercise, and sleep
