The authors propose a new framework for the thalamus in cognition. They review findings from rodents and primates, emphasizing thalamic control of functional cortical connectivity, its putative mechanisms and role in flexible construction of task-relevant cortical networks.
Synaptic integration is critical for determining how information in the brain is encoded, stored and retrieved. The authors review roles for synaptic integrative mechanisms in the selection, generation and plasticity of spatially modulated firing, and in related temporal codes for representation of space.
Cognitive maps are internal representations of large-scale navigable spaces. While they have been long studied in rodents, recent work in humans reveals new insights into how cognitive maps are encoded, anchored to environmental landmarks and used to plan routes. Similar neural mechanisms might be used to form ‘maps’ of nonphysical spaces.
Distinct processing of objects and space has been an organizing principle for studying higher-level vision and medial temporal lobe memory. Here Connor and Knierim discuss instead how spatial information, on both local and global scales, is deeply integrated into the ventral-temporal object-processing pathway in vision and memory.
Hattori et al. review the recent advances in our understanding of the roles of inhibitory neuron subtypes in shaping the activity and plasticity states of neocortical circuits, how neuromodulators control inhibitory neuron subtypes, and the role of inhibitory neuron dysfunction in neurological disorders.
The consequences of spinal cord injury are often severe and irreversible; cell transplantation has emerged as a potential treatment. In this Review, the authors highlight mechanisms through which cell transplantation is thought to promote functional improvements and the obstacles to making cell transplantation a viable therapy.
Cognitive activity requires the collective behavior of cortical, thalamic and spinal neurons across large-scale systems of the CNS. This paper provides an illustrated introduction to dynamic models of large-scale brain activity, from the tenets of the underlying theory to challenges, controversies and recent breakthroughs.
Network neuroscience tackles the challenge of discovering the principles underlying complex brain function and cognition from an explicitly integrative perspective. Here, the authors discuss emerging trends in network neuroscience, charting a path towards a better understanding of the brain that bridges computation, theory and experiment across spatial scales and species.
Magnetoencephalography (MEG) tracks the millisecond electrical activity of the brain noninvasively. This review emphasizes MEG's unique assets, especially in terms of imaging and resolving the mechanisms underlying the apparent complexity of polyrhythmic brain dynamics. It also identifies practical challenges and clarifies misconceptions about the technique.
Neuroimaging and pattern recognition are being combined to develop brain models of clinical disorders. Such models yield biomarkers that can be shared and validated across populations, narrowing the gap between neuroscience and clinical applications. The authors summarize 475 translational modeling studies, highlighting challenges and ways to improve biomarker development.
The study of neuroanatomy using MRI enables key insights into how our brains function, are shaped by genes and environment, and how they change with development, aging and disease. The authors provide an overview of the methods for measuring the brain and also describe key artifacts and confounds
Historically, the CNS has been considered immunologically privileged and separated from the peripheral immune system. In this Review, the authors highlight recent advances in our understanding of how the CNS interacts with peripheral immune cells in the context of health and disease.
Neural pathways regulate immune responses and inflammation. Recent research using technological advances in molecular genetics has provided important insights into the functional anatomy and cellular and molecular mechanisms of this regulation. These advances resulted in clinical trials exploring neuromodulation in the treatment of inflammatory and autoimmune disorders.
