    Neural excitability and sensory input determine intensity perception with opposing directions in initial cortical responses

    Tilman Stephani, Alice Hodapp ... Vadim V Nikulin
    Larger evoked responses during initial cortical processing may reflect states of lower excitability.

    Intrinsic excitability mechanisms of neuronal ensemble formation

    Tzitzitlini Alejandre-García, Samuel Kim ... Rafael Yuste
    Optogenetic and electrical stimulation of primary visual cortex neurons reveals synaptic and cell-intrinsic mechanisms that underlie neuronal ensemble formation.
    1. Neuroscience

    Respiration aligns perception with neural excitability

    Daniel S Kluger, Elio Balestrieri ... Joachim Gross
    Noninvasive human magnetoencephalography recordings characterize the functional relationship between respiration, neural oscillations, and performance in low-level perception.

    Sleep-dependent upscaled excitability, saturated neuroplasticity, and modulated cognition in the human brain

    Mohammad Ali Salehinejad, Elham Ghanavati ... Michael A Nitsche
    The sleep-deprived brain in humans undergoes upscaled intracortical excitability which diminishes induction of LTP-like plasticity via transcranial electrical stimulation while converting the LTD-like to LTP-like plasticity and these physiological changes couple with impaired learning, memory, and attention at behavioral level.

    Rem2 stabilizes intrinsic excitability and spontaneous firing in visual circuits

    Anna R Moore, Sarah E Richards ... Suzanne Paradis
    In vivo and ex vivo analysis of the activity-regulated gene Rem2 in the mouse visual system sheds new light on the contribution of intrinsic excitability in circuit plasticity.
    1. Neuroscience

    Synchronized excitability in a network enables generation of internal neuronal sequences

    Yingxue Wang, Zachary Roth, Eva Pastalkova
    Hippocampal sharp-wave sequences, which are considered the key phenomenon underlying consolidation of episodic memory, are preserved even after an animal’s memory is impaired.
    1. Neuroscience

    Criticality and degeneracy in injury-induced changes in primary afferent excitability and the implications for neuropathic pain

    Stéphanie Ratté, Yi Zhu ... Steven A Prescott
    No single molecular change is uniquely necessary to cause neuropathic changes in primary afferent excitability; multiple different changes are sufficient.
    1. Neuroscience

    Enhanced excitability of cortical neurons in low-divalent solutions is primarily mediated by altered voltage-dependence of voltage-gated sodium channels

    Briana J Martiszus, Timur Tsintsadze ... Stephen M Smith
    External calcium regulates neuronal excitability via its actions on voltage-gated sodium channels but not by regulating NALCN via the calcium-sensing receptor.
    1. Neuroscience

    Deletion of Stk11 and Fos in mouse BLA projection neurons alters intrinsic excitability and impairs formation of long-term aversive memory

    David Levitan, Chenghao Liu ... Sacha B Nelson
    Stk11 and Fos expression plays an important role in CTA long-term memory formation by modulating the intrinsic excitability of BLApn.
