Abstract

This review is yet another attempt to explain how echolocation in bats or bat-like mammals came into existence. Attention is focused on neuronal specializations in the ascending auditory pathway of echolocating bats. Three different mechanisms are considered that may create a specific auditory sensitivity to echos: (1). time-windows of enhanced echo-processing opened by a corollary discharge of neuronal vocalization commands; (2). differentiation and expansion of ensembles of combination-sensitive neurons in the midbrain; and (3). corticofugal top-down modulations. The second part of the review interprets three different types of echolocation as adaptations to ecological niches, and presents the sophisticated cochlear specializations in constant-frequency/frequency-modulated bats as a case study of finely tuned differentiation. It is briefly discussed how a resonant mechanism in the inner ear of constant-frequency/frequency-modulated bats may have evolved in common mammalian cochlea.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sensory consequences of self-generated actions are normally the most predictable and least salient events, estimated accurately from corollary discharges via a forward model.

    “The sensory consequences of self-generated actions are normally the most predictable and thus least salient of events, as they are typically estimated accurately from corollary discharges via a forward model.51,52”

  • Bats explore the environment by emitting high-intensity, high-frequency beams of sound and then comparing spatiotemporal aspects of the returning echo with the emitted sound.

  • Neurons sensitive to specific emission-echo intervals have been identified in the inferior colliculus and, together with corollary discharge, have a key role in the neural circuitry for auditory-scene analysis.

    “Neurons that are sensitive to specific emission–echo intervals have been identified in the inferior colliculus (FIG. 5Ba) and, together with CD, have a key role in the neural circuitry for auditory-scene analysis54,58.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
