  • Brainstem Circuits Controlling Action Diversification.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2019-07-08
    Ludwig Ruder,Silvia Arber

    Neuronal circuits that regulate movement are distributed throughout the nervous system. The brainstem is an important interface between upper motor centers involved in action planning and circuits in the spinal cord ultimately leading to execution of body movements. Here we focus on recent work using genetic and viral entry points to reveal the identity of functionally dedicated and frequently spatially

    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-06-19
    Katsuyuki Sakai

    A task set is a configuration of cognitive processes that is actively maintained for subsequent task performance. Single-unit and brain-imaging studies have identified the neural correlates for task sets in the prefrontal cortex. Here I examine whether the neural data obtained thus far are sufficient to explain the behaviors that have been illustrated within the conceptual framework of task sets. I

  • Descending pathways in motor control.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-06-19
    Roger N Lemon

    Each of the descending pathways involved in motor control has a number of anatomical, molecular, pharmacological, and neuroinformatic characteristics. They are differentially involved in motor control, a process that results from operations involving the entire motor network rather than from the brain commanding the spinal cord. A given pathway can have many functional roles. This review explores to

  • Role of axonal transport in neurodegenerative diseases.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-06-19
    Kurt J De Vos,Andrew J Grierson,Steven Ackerley,Christopher C J Miller

    Many major human neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS), display axonal pathologies including abnormal accumulations of proteins and organelles. Such pathologies highlight damage to the axon as part of the pathogenic process and, in particular, damage to transport of cargoes through axons. Indeed, we now know that disruption

  • Brain circuits for the internal monitoring of movements.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-06-19
    Marc A Sommer,Robert H Wurtz

    Each movement we make activates our own sensory receptors, thus causing a problem for the brain: the spurious, movement-related sensations must be discriminated from the sensory inputs that really matter, those representing our environment. Here we consider circuits for solving this problem in the primate brain. Such circuits convey a copy of each motor command, known as a corollary discharge (CD)

  • Active and passive immunotherapy for neurodegenerative disorders.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-03-21
    David L Brody,David M Holtzman

    Immunotherapeutic strategies to combat neurodegenerative disorders have galvanized the scientific community since the first dramatic successes in mouse models recreating aspects of Alzheimer disease (AD) were reported. However, initial human trials of active amyloid-beta (Abeta) vaccination were halted early because of a serious safety issue: meningoencephalitis in 6% of subjects. Nonetheless, some

  • Vestibular system: the many facets of a multimodal sense.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-03-15
    Dora E Angelaki,Kathleen E Cullen

    Elegant sensory structures in the inner ear have evolved to measure head motion. These vestibular receptors consist of highly conserved semicircular canals and otolith organs. Unlike other senses, vestibular information in the central nervous system becomes immediately multisensory and multimodal. There is no overt, readily recognizable conscious sensation from these organs, yet vestibular signals

  • Mitochondrial disorders in the nervous system.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-03-13
    Salvatore DiMauro,Eric A Schon

    Mitochondrial diseases (encephalomyopathies) have traditionally been ascribed to defects of the respiratory chain, which has helped researchers explain their genetic and clinical complexity. However, other mitochondrial functions are greatly important for the nervous system, including protein importation, organellar dynamics, and programmed cell death. Defects in genes controlling these functions are

  • Balancing structure and function at hippocampal dendritic spines.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-02-21
    Jennifer N Bourne,Kristen M Harris

    Dendritic spines are the primary recipients of excitatory input in the central nervous system. They provide biochemical compartments that locally control the signaling mechanisms at individual synapses. Hippocampal spines show structural plasticity as the basis for the physiological changes in synaptic efficacy that underlie learning and memory. Spine structure is regulated by molecular mechanisms

  • Place cells, grid cells, and the brain's spatial representation system.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-02-21
    Edvard I Moser,Emilio Kropff,May-Britt Moser

    More than three decades of research have demonstrated a role for hippocampal place cells in representation of the spatial environment in the brain. New studies have shown that place cells are part of a broader circuit for dynamic representation of self-location. A key component of this network is the entorhinal grid cells, which, by virtue of their tessellating firing fields, may provide the elements

  • Cerebellum-like structures and their implications for cerebellar function.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-02-16
    Curtis C Bell,Victor Han,Nathaniel B Sawtell

    The nervous systems of most vertebrates include both the cerebellum and structures that are architecturally similar to the cerebellum. The cerebellum-like structures are sensory structures that receive input from the periphery in their deep layers and parallel fiber input in their molecular layers. This review describes these cerebellum-like structures and compares them with the cerebellum itself.

  • Spike timing-dependent plasticity: a Hebbian learning rule.
    Annu. Rev. Neurosci. (IF 12.547) Pub Date : 2008-02-16
    Natalia Caporale,Yang Dan

    Spike timing-dependent plasticity (STDP) as a Hebbian synaptic learning rule has been demonstrated in various neural circuits over a wide spectrum of species, from insects to humans. The dependence of synaptic modification on the order of pre- and postsynaptic spiking within a critical window of tens of milliseconds has profound functional implications. Over the past decade, significant progress has
