    Traditionally, the CNS is described to have immune privilege, largely because of its immunological barriers. Here, Forrester, McMenamin and Dando describe how this immune privilege may sometimes not be beneficial, as it enables invading pathogens to exist as latent CNS infections.

    Age-related changes in cognitive ability are the focus of a growing field of research. Cabeza, Rajah and colleagues aim to promote clarity in the field by agreeing upon consensual definitions for three widely discussed concepts: maintenance, compensation and reserve.

    The brain can be parcellated into areas or networks with different structural or functional properties. Eickhoff, Yeo and Genon describe various imaging-based strategies to parcellate the human brain, including those based on local properties, such as cytoarchitecture, and global properties, such as connectivity.

    Various techniques can be used to image aspects of the pathophysiology of Alzheimer disease in humans, notably protein deposition and neurodegeneration. In this Review, William Jagust discusses how human neuroimaging studies have shaped our understanding of this disease.

    Technological advances have allowed the molecular ‘signatures’ of microglia to be characterized, providing insight into their roles in CNS function. Weiner and Butovsky discuss the plasticity of these signatures in health and disease and consider the mechanisms underlying their establishment, maintenance and regulation.

    Study shows that population activity in the rat lateral entorhinal cortex can encode the passage of time, which may contribute to temporal aspects of episodic memory.

    Hippocampal cannabinoid 1 receptors are shown to be involved in the formation of incidental associations between pairs of low-salience sensory stimuli, which can then become indirectly associated with certain cues and thus influence behaviour.
