    Dynamic representation of 3D auditory space in the midbrain of the free-flying echolocating bat

    Ninad B Kothari et al.
    Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.

    Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

    Danuta M Wisniewska et al.
    Harbor porpoises dynamically control biosonar field of view as they track and capture prey, focusing the beam through deformations to the melon.

    Place recognition using batlike sonar

    Dieter Vanderelst et al.
    Echolocating bats may recognize locations in the environment (and navigate to them) by remembering the specific echo signature of those locations.

    Acoustic shadows help gleaning bats find prey, but may be defeated by prey acoustic camouflage on rough surfaces

    Elizabeth L Clare, Marc W Holderied
    Some species of bats hunt for insects that are resting on surfaces by detecting interruptions in the echoes from that surface, suggesting that resting on rough surfaces may help insects to evade detection by echolocation.

    A sensorimotor model shows why a spectral jamming avoidance response does not help bats deal with jamming

    Omer Mazar, Yossi Yovel
    An elaborated bat-predator model shows that even in high bat-densities, bats can successfully catch flying insects and that changing their signals’ frequency is not necessary for dealing with sensory interference.

    A cerebellar substrate for cognition evolved multiple times independently in mammals

    Jeroen B Smaers et al.
    Multiple independent directional selection events on a neural substrate that underpins domain-general associative abilities partly explains independent occurrences of complex behavior in different lineages of mammals.

    Echolocation: Smart bats click twice

    Manfred Kössl, Julio Hechavarría
    The acoustic representation of the outside world in the midbrain of a bat becomes more precise as it uses double clicks to locate closer objects.

    Fundamental constraints in synchronous muscle limit superfast motor control in vertebrates

    Andrew F Mead et al.
    Vertebrate superfast muscles employ similar excitation–contraction strategies but distinct myosin heavy chain genes to allow superfast performance, revealing a maximum speed that cannot be overcome without sacrificing neural control.

    Admixture into and within sub-Saharan Africa

    George BJ Busby et al.
    Gene flow analysis reveals that the genomes of most sub-Saharan populations are the result of recent historical admixture events.
