    In this episode, we hear about self-esteem, a new genus of extinct horse, the future of biological engineering, mosquito trackers, and sperm competition in salmon.
  2. Episode 53: January 2019

    In this episode, we hear about memory consolidation, breast cancer, leafcutter ants, deep-sea biodiversity and the beneficial effects of oxytocin on our health.

    Integrative and distinctive coding of visual and conceptual object features in the ventral visual stream

    Chris B Martin et al.
    Perirhinal cortex, a brain structure located in the medial temporal lobe, uniquely supports the integration of visual and conceptual object information.

    Secretagogin expression delineates functionally-specialized populations of striatal parvalbumin-containing interneurons

    Farid N Garas et al.
    In rodents and primates, there are two subtypes of parvalbumin-expressing interneurons that provide novel substrates for selective inhibition in the striatum.

    Corticothalamic phase synchrony and cross-frequency coupling predict human memory formation

    Catherine M Sweeney-Reed et al.
    Direct electrophysiological evidence demonstrates a role for the anterior thalamic nucleus in human memory formation.

    Ventrolateral periaqueductal gray neurons prioritize threat probability over fear output

    Kristina M Wright, Michael A McDannald
    Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.

    Lateral orbitofrontal neurons acquire responses to upshifted, downshifted, or blocked cues during unblocking

    Nina Lopatina et al.
    Building on previous work (McDannald et. al, 2014), it is shown that dissociable populations of neurons in the lateral orbitofrontal cortex acquire responses to cues that predict more, less, or no change in reward in rats during training in a Pavlovian unblocking task.

    Rat anterior cingulate cortex recalls features of remote reward locations after disfavoured reinforcements

    Ali Mashhoori et al.
    The anterior cingulate cortex intermixes a precise spatial map with a cognitive map of the task, and spontaneously recalls multimodal information about unrealized choice outcomes during pauses in behavior after reinforcements.
    1. Neuroscience

    A role for descending auditory cortical projections in songbird vocal learning

    Yael Mandelblat-Cerf et al.
    Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.
    1. Neuroscience

    Intermittent subthalamic nucleus deep brain stimulation induces risk-aversive behavior in human subjects

    Shaun R Patel et al.
    Deep brain stimulation can selectively modify neural activity within the subthalamic nucleus to modify decisions under uncertainty in human subjects.
