Vib2Sound: Separation of Multimodal Sound Sources

This paper introduces a neural network system for separating overlapping vocalizations using multi-channel microphone and accelerometer data from zebra finches.

Estimating the motor exploration in reinforcement learning

The paper estimates motor exploration strategies in songbirds using a reinforcement learning framework and finds that non-ideal variability aligns with suboptimal learning trajectories.

Sharp waves, bursts, and coherence: Activity in a songbird vocal circuit is influenced by behavioral state

The paper investigates neural activity patterns in the songbird anterior forebrain pathway during sleep and awake states, finding synchronized bursts in LMAN during NREM sleep similar to hippocampal sharp-wave ripples.

Visually-guided compensation of deafening-induced song deterioration

This study shows that deafened songbirds can maintain song stability using visual cues, as demonstrated by a new metric and behavioral task.

Familiarity of an environment prevents song suppression in isolated zebra finches

This study finds that social isolation in a familiar environment does not suppress singing in zebra finches, unlike isolation in an unfamiliar environment.

Goal-directed vocal planning in a songbird

This study shows zebra finches can plan vocal changes to recover a target song without immediate sensory experience.

Sensory substitution reveals a manipulation bias

This study uses sensory substitution in deaf songbirds to show that visual feedback can drive vocal learning and reveal a bias for actions that provide feedback.

Fast retrograde access to projection neuron circuits underlying vocal learning in songbirds

The paper introduces a viral tool for fast retrograde labeling of projection neurons in songbirds and mice, enabling detailed analysis of vocal learning circuits.

Neighborhood-statistics reveal complex dynamics of song acquisition in the zebra finch

The paper introduces a nearest-neighbor method to analyze song development in zebra finches, revealing complex temporal dynamics in vocal learning and development.

Transitioning between preparatory and precisely sequenced neuronal activity in production of a skilled behavior

The paper identifies neuronal populations in songbirds that transition from preparatory activity to precise sequences during singing, revealing mechanisms for behavioral state transitions.

Magnetic Ultrathin Tissue Sections for Ease of Light and Electron Microscopy

The paper discusses the removal of a manuscript due to a ruling by ETH Zurich.

Welfare of zebra finches used in research

The paper reviews manipulations in zebra finch research and assesses their impact on animal welfare, identifying singing rate as a potential welfare indicator.
