    Three rules govern thalamocortical connectivity of fast-spike inhibitory interneurons in the visual cortex

    Yulia Bereshpolova et al.
    In the visual system, three rules guide the thalamocortical connectivity of cortical fast-spike interneurons and are key to understand the potent and broadly tuned feed-forward inhibition that they generate.

    Movement-related coupling of human subthalamic nucleus spikes to cortical gamma

    Petra Fischer et al.
    When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.

    Dendritic sodium spikes are required for long-term potentiation at distal synapses on hippocampal pyramidal neurons

    Yujin Kim et al.
    At distal synapses onto hippocampal CA1 pyramidal neurons, synaptic plasticity is dependent on dendritically initiated sodium spikes, thus establishing a new role for voltage-gated sodium channels in the dendrites that may have important implications for how learning rules are implemented.

    Selective attenuation of Ether-a-go-go related K+ currents by endogenous acetylcholine reduces spike-frequency adaptation and network correlation

    Edward D Cui, Ben W Strowbridge
    Acetylcholine, a common modulator in the brain, controls spike-frequency adaptation by specifically attenuating Ether-a-go-go related K+ currents, thereby explaining many cortical network statistical changes often observed in vivo.

    Distinct responses of Purkinje neurons and roles of simple spikes during associative motor learning in larval zebrafish

    Thomas C Harmon et al.
    Discrete classes of cerebellar Purkinje neurons show distinct changes in synaptic and spiking activity during motor learning, with simple spikes playing a shifting role during acquisition, expression, and maintenance of learned responses.

    Palmitoylation of LIM Kinase-1 ensures spine-specific actin polymerization and morphological plasticity

    Joju George et al.
    The protein-lipid modification palmitoylation targets the kinase LIMK1 to dendritic spines to ensure precise control of the size of individual spines in response to synaptic activation.

    NMDA spikes mediate amplification of inputs in the rat piriform cortex

    Amit Kumar et al.
    Dendrites of pyramidal neurons in piriform cortex can initiate NMDA spikes, which may serve to amplify odor responses, and provide combination selectivity underlying 'discontinuous' odor receptive fields in these neurons.

    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui et al.
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.

    Ultrastructural comparison of dendritic spine morphology preserved with cryo and chemical fixation

    Hiromi Tamada et al.
    Cryo preservation of brain tissue reveals dendritic spines with thinner necks compared to those prepared with chemical fixation.

    Tactile sensory channels over-ruled by frequency decoding system that utilizes spike pattern regardless of receptor type

    Ingvars Birznieks et al.
    Perception of vibrotactile frequency depends on the neural discharge pattern rather than the afferent type, thus requiring a reevaluation of the notion of Pacinian/non-Pacinian channels in tactile sensory system.
