ABSTRACT Background: In mild Alzheimer's disease (AD), a deficit in episodic memory, particularly autobiographical memory, is clearly established. Several recent studies have also shown impaired semantic memory from the onset of the disease. Musical memory capacities may be especially preserved and listening to music might encourage autobiographical recall. The aim ...

Research on retrieval suppression has produced varying results concerning whether negatively valenced memories are more or less suppressible than neutral memories. This variability may arise if, across studies, participants adopt different approaches to memory control. Cognitive and neurobiological research points to two mechanisms that achieve retrieval suppression: thought-substitution and direct ...

Identifying the signalling pathways underlying the pathophysiology of schizophrenia is an essential step in the rational development of new antipsychotic drugs for this devastating disease. Evidence from genetic, transgenic and post-mortem studies have strongly supported neuregulin-1 (NRG1)-ErbB4 signalling as a schizophrenia susceptibility pathway. NRG1-ErbB4 signalling plays crucial roles in regulating ...
