Our brains hold a seemingly endless amount of information, from childhood memories to our home addresses. Not only neuroscience is already attempting to answer the question how are we able to learn, store, and recall all this information with such ease?
In a special issue of Biology we are going to rely on the huge range of concepts and techniques, from molecular events in the nervous system and human system neuroscientific approaches, to computational models aiming at a holistic picture of the neural mechanisms involved.
Advances in molecular biology and genetics are offering new clues about key molecules and proteins that influence memory. Research at the cellular level has shown that brain cells undergo chemical and structural changes during learning by changing the number or strength of connections between themselves. Recent animal studies suggest that manipulating these molecules could lead to new ways of modifying memories. Other studies on human participants have attempted to identify how different areas of the brain work together to enhance memory formation and storage.
For this special issue of Biology, we invite research articles from any field of neuroscience to help expand our understanding of the neural mechanisms of learning and memory.

Abstract: Memory consists of various individual processes which form a dynamic system co-ordinated by central (executive) functions. The episodic buffer as direct interface between episodic long-term memory (LTM) and working memory (WM) is fairly well studied but such direct interaction is less clear in semantic LTM. Here we designed a verbal late-match-to-sample task specifically to differentiate between pure information maintenance and mental manipulation of memory traces with and without involvement of access to semantic LTM. Task-related amplitude differences of electroencephalographic (EEG) oscillatory brain activity showed a linear increase in frontal-midline theta and linear suppression of parietal beta amplitudes relative to memory operation complexity. Amplitude suppression at fast alpha frequency, which was previously found to indicate access to semantic LTM, was only sensitive to mental manipulation in general, irrespective of LTM involvement.
This suggests that suppression of fast EEG alpha activity might rather reflect unspecific distributed cortical activation during complex mental processes than accessing semantic LTM.
