    Selection of distinct populations of dentate granule cells in response to inputs as a mechanism for pattern separation in mice

    Wei Deng et al.
    By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

    Acute stress enhances adult rat hippocampal neurogenesis and activation of newborn neurons via secreted astrocytic FGF2

    Elizabeth D Kirby et al.
    Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

    Decoding the neural mechanisms of human tool use

    Jason P Gallivan et al.
    Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

    Dismantling the Papez circuit for memory in rats

    Seralynne D Vann
    In contrast to current models, inputs from midbrain limbic structures, but not from the hippocampus, are necessary for mammillary body contributions to memory.

    Pro-social behavior in rats is modulated by social experience

    Inbal Ben-Ami Bartal et al.
    Rats show socially selective helping behavior based on familiarity with the type of rat, but not necessarily the individual rat.

    Re-examining how complexin inhibits neurotransmitter release

    Thorsten Trimbuch et al.
    Challenging a widespread model, biophysical and electrophysiological experiments suggest a new mechanism whereby complexins inhibit neurotransmitter release through electrostatic repulsion between their accessory helix and the membranes.

    Enhancement of fear memory by retrieval through reconsolidation

    Hotaka Fukushima et al.
    Retrieval enhances fear memory through reconsolidation by activating calcineurin-induced protein degradation and CREB-mediated gene expression in amygdala, hippocampus, and mPFC.
    1. Neuroscience

    Loss of Cdc42 leads to defects in synaptic plasticity and remote memory recall

    Il Hwan Kim et al.
    Conditional knockout of the small GTPase Cdc42 in excitatory neurons of the mouse forebrain leads to impaired long-term synaptic plasticity and impaired retrieval of remote memory.

    Autism and attention-deficit/hyperactivity disorder among individuals with a family history of alcohol use disorders

    Jan Sundquist et al.
    A Swedish national cohort study reveals that children with a family history of alcohol use disorders have an increased risk of autism and attention-deficit/hyperactivity disorder.
    1. Neuroscience

    Amygdala neural activity reflects spatial attention towards stimuli promising reward or threatening punishment

    Christopher J Peck, C Daniel Salzman
    Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.
