Neural Plasticity: Dopamine Tunes the Mushroom Body Output Network
Two recent studies in Drosophila provide evidence that dopamine can drive synaptic depression and facilitation, supporting models in which learning and the behavioral state of the fly guide behavior by tuning mushroom body output synapses.

of time the influence of matter on life and mind will gradually become obliterated and replaced by the influence of mind and its transcendent successors in the great steps of creative evolution." Therefore, "the remote successors of man may be free and independent of matter with infinite possibilities of future progress notwithstanding the complete dissolution of the universe." Pure thought, th...
متن کاملEndotracheal cardiac output monitor.
BACKGROUND The endotracheal cardiac output monitor (ECOM) is a new device that uses an endotracheal tube with multiple electrodes to measure cardiac output (CO). It measures the changes in electrical impedance caused by pulsatile blood flow in the aorta. The system was tested for safety and efficacy in 10 swine. METHODS Swine (60-80 kg) were chronically instrumented with a transit time flow p...
متن کاملCardiac output by Portapres.
Portapres derives continuous estimates of cardiac output from the peripheral pulse and has the potential to be an extremely valuable physiological and clinical tool. We assessed Portapres estimates of cardiac output in healthy subjects at rest, during maximal treadmill exercise ( n = 8) and during decreases caused by orthostatic stress ( n = 8). Comparison with a rebreathing method indicated th...
متن کاملMeasurement of cardiac output.
Float catheterisation of the pulmonary artery was described in The Lancet by Dr R D Bradley (as he then was) in 1964 at a time when invasive circulatory monitoring was almost non-existent outside cardiac surgical units, and ‘intensive care’ was a term barely in use. Cardiac catheterisation was laboratory based and required radiological control: management of acute circulatory crises relied on c...
