Memory formation is one of the most fascinating and complex brain functions. Today, we have a detailed knowledge about synaptic plasticity, the putative mechanism underlying learning at the level of single neurons. In contrast, we know much less about how memory formation affects the routing and processing of information in neuronal circuits. For a long time, understanding this question has posed a formidable task to the experimenter. Recent technical advances such as in vivo 2-photon imaging and viral and transgenic strategies to identify subtypes of neurons have triggered great advances, making this a very dynamic field of study.

We invite authors to contribute original articles as well as review articles that showcase recent advances in neuronal circuit memory. Potential topics include, but are not limited to:

• Network mechanisms of sensory deprivation and enrichment
• Circuit plasticity in response to associative learning
• Circuit plasticity in response to motor learning
• Plasticity of internal representations such as space, movement, cognition
• Theoretical studies of network plasticity

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/np/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
