    Sleep is bi-directionally modified by amyloid beta oligomers

    Güliz Gürel Özcan, Sumi Lim ... Jason Rihel
    Amyloid beta, the major component of plaques in Alzheimer's disease, acutely and reversibly signals to modulate sleep as a function of oligomeric length, independently of neuronal loss.

    Recurrent circuitry is required to stabilize piriform cortex odor representations across brain states

    Kevin A Bolding, Shivathmihai Nagappan ... Kevin M Franks
    Intracortical circuits in mouse olfactory cortex stabilize odor-evoked activity patterns when upstream inputs, from olfactory bulb, become degraded under anesthesia.

    Estimating and interpreting nonlinear receptive field of sensory neural responses with deep neural network models

    Menoua Keshishian, Hassan Akbari ... Nima Mesgarani
    A comprehensive, data-driven and interpretable nonlinear computational modeling framework based on deep neural networks uncovers different nonlinear transformations of speech signal in the human auditory cortex.

    A Matlab-based toolbox for characterizing behavior of rodents engaged in string-pulling

    Samsoon Inayat, Surjeet Singh ... Majid H Mohajerani
    Analysis methods for video data of rodents engaged in string-pulling behavior have been developed and used to highlight differences in motion profiles of Swiss Webster and C57Bl/6 mice.

    A size principle for recruitment of Drosophila leg motor neurons

    Anthony W Azevedo, Evyn S Dickinson ... John C Tuthill
    Motor neurons controlling the leg of the fruit fly exhibit a gradient of physiological and functional properties that correlate with the order in which they fire during behavior.

    Whole-organism behavioral profiling reveals a role for dopamine in state-dependent motor program coupling in C. elegans

    Nathan Cermak, Stephanie K Yu ... Steven W Flavell
    Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.
    1. Neuroscience

    Different dendritic domains of the GnRH neuron underlie the pulse and surge modes of GnRH secretion in female mice

    Li Wang, Wenya Guo ... Yanping Kuang
    Electrical activity at the gonadotropin-releasing hormone (GnRH) neuron cell body and proximal dendrites is not required for the pulsatile secretion of GnRH that controls fertility.

    Dynamic behavior of the locus coeruleus during arousal-related memory processing in a multi-modal 7T fMRI paradigm

    Heidi IL Jacobs, Nikos Priovoulos ... Kâmil Uludağ
    By combining ultra-high-field imaging with physiological and saliva measures it is established that interactions between locus coeruleus, hippocampus and amygdala vary along emotional memory stages, putatively reflecting distinct cognitive states.
    1. Neuroscience

    Different methods of fear reduction are supported by distinct cortical substrates

    Belinda PP Lay, Audrey A Pitaru ... Mihaela D Iordanova
    Extinction and overexpectation lead to the same behavioural outcome, that is, reduction in learned fear, but engage different cortical areas.

    Control of adaptive action selection by secondary motor cortex during flexible visual categorization

    Tian-Yi Wang, Jing Liu, Haishan Yao
    The secondary motor cortex causally contributes to flexible action selection during stimulus categorization with the representations of upcoming choice and sensory history regulated by the demand to remap stimulus–action association.
