Emotion: Systems, Cells, Synaptic Plasticity

The history of neuroscience in the 20th century is punctuated by periods in which the neural basis of emotion has been avidly studied and discussed. We are now in such a period, one marked by technical and conceptual advances that allow a consideration of emotional processes in terms of neuroanatomical circuits, cellular functions, and molecules. This short article will survey some of the recent advances.
