Lledo and colleagues provide an up-to-date review of recent developments in our understanding of neurogenesis in the adult brain, with a comparative view of the generation of new neurons in the olfactory bulb and the dentate gyrus.
Astrocytes are not mere 'brain glue', but direct, active communication partners of neurons. Seifert and colleagues discuss their roles in the pathogenesis of several neurological disorders, and argue that these cells might present a therapeutic target in treating these diseases.
Mitochondrial dysfunction has long been implicated in Parkinson's disease. Wood and colleagues review recent evidence on the roles of the genes associated with the disease in mitochondrial pathways, highlighting the involvement of oxidative stress in the aetiology of the disorder.
Komatsu provides several striking examples of filling-in — in which a region of the visual field is filled in with the visual attributes of its surround — before considering possible neural mechanisms underlying this remarkable perceptual phenomenon.
Feldman and Del Negro consider recent evidence for two distinct respiratory rhythm generators – the preBötzinger Complex and the retrotrapezoid nucleus/parafacial respiratory group – and underscore the importance of intrinsically rhythmic pacemaker neurons that drive rhythm generation.
Emotional body language is a rapidly emerging research field in cognitive neuroscience. de Gelder reviews the body's role in our understanding of emotion, action and communication, and discusses similarities in the neuroanatomy and temporal dynamics between face and body perception.
