Neurons and neuronal networks decide, remember, modulate, and control an animal¹s every sensation, thought, movement, and act. The intimate details of this network, including the dynamical properties of individual and populations of neurons, give a nervous system the power to control a wide array of behavioral functions. We want to know more about neuronal dynamics and networks; about synaptic interactions between neurons; about how neuronal signaling and behavior and control and environmental stimuli are inextricably linked.
