The aged human auditory cortex shows preserved tonotopy, but temporal modulations are represented with a markedly broader tuning, highlighting decreased temporal selectivity as a hallmark of the aging auditory cortex.

Neurons in human dorsal motor cortex, an area involved in controlling arm and hand movements, are also active – and show similar ensemble dynamics – during speaking.

Ear canal EEG and pupillometry reveal disordered temporal processing in adults with normal hearing who struggle to understand conversations in noisy backgrounds.
Keeping flexible adaptable representations of speech categories at different time scales allows the brain to maintain stable perception in the face of varying speech sound characteristics.

Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.

Deep neural network modeling of auditory processing identifies distorted cross-frequency interactions as the key problem for the processing of speech in noise after hearing loss.

The genetic and behavioral diversity of the zebra finch, both in the wild and in captivity, make it well-suited for neuroethological studies of vocal learning, culture, and social bonding.

The neural response to natural speech and music processing is mostly shared between the domains, with additional evidence for selectivity in distributed (i.e. not regional) and frequency-specific neural activity.
Single-neuron recordings in the inferior frontal cortex of trained macaques show neurons that are selective to the volitional preparation of either vocal or manual actions.
