    Scn1a-GFP transgenic mouse revealed Nav1.1 expression in neocortical pyramidal tract projection neurons

    Tetsushi Yamagata, Ikuo Ogiwara ... Kazuhiro Yamakawa
    In neocortex, Nav1.1 is expressed in neocortical pyramidal tract projection neurons and a minor subpopulation of cortico-cortical projection neurons in addition to its predominant expression in inhibitory neurons, while the majority of cortico-thalamic, cortico-striatal, and cortico-cortical neurons express Nav1.2.

    Target-specific membrane potential dynamics of neocortical projection neurons during goal-directed behavior

    Takayuki Yamashita, Carl CH Petersen
    A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.

    Visual projection neurons in the Drosophila lobula link feature detection to distinct behavioral programs

    Ming Wu, Aljoscha Nern ... Gerald M Rubin
    Neurons called lobula columnar cells help fruit flies respond appropriately to specific visual cues, such as those signaling an approaching predator.

    N-cadherin-regulated FGFR ubiquitination and degradation control mammalian neocortical projection neuron migration

    Elif Kon, Elisa Calvo-Jiménez ... Yves Jossin
    FGFRs regulate multipolar cortical neuron orientation and the morphological change into bipolar cells in vivo under the control of N-Cadherin and the extracellular matrix protein Reelin.

    Projection neurons are necessary for the maintenance of the mouse olfactory circuit

    Luis Sánchez-Guardado, Peyman Razavi ... Carlos Lois
    Ablation of olfactory projection neurons in adult mice triggers sprouting of the apical dendrite of remaining neurons towards multiple nearby glomeruli and disrupts the odor map.

    A projection specific logic to sampling visual inputs in mouse superior colliculus

    Katja Reinhard, Chen Li ... Karl Farrow
    Transsynaptic viral tracing reveals that neurons in the superior colliculus employ projection specific rules to the sampling of retinal inputs, directing distinct visual features to different downstream targets.

    A tonic nicotinic brake controls spike timing in striatal spiny projection neurons

    Lior Matityahu, Jeffrey M Malgady ... Joshua L Plotkin
    A novel mechanism describes how tonic activation of nicotinic acetylcholine receptors can modulate the timing of striatal output by priming feedforward inhibition.

    What is the true discharge rate and pattern of the striatal projection neurons in Parkinson’s disease and Dystonia?

    Dan Valsky, Shai Heiman Grosberg ... Marc Deffains
    Aberrant striatal signaling does not induce drastic changes in the spontaneous discharge rate and pattern of the striatal projection neurons in Parkinson’s disease and Dystonia.

    Inhibition of oxidative stress in cholinergic projection neurons fully rescues aging-associated olfactory circuit degeneration in Drosophila

    Ashiq Hussain, Atefeh Pooryasin ... Ilona C Grunwald Kadow
    Drosophila genetics and behavior reveal that oxidative stress induced axonal degeneration in a single class of neurons drives the functional decline of an entire neural network and the behavior it controls.

    Mutant huntingtin enhances activation of dendritic Kv4 K+ channels in striatal spiny projection neurons

    Luis Carrillo-Reid, Michelle Day ... D James Surmeier
    In mouse models of Huntington's disease, striatal spiny projection neurons up-regulate dendritic potassium channels, which impairs their normal function, but a zinc finger gene therapy can reverse this deficit.
