The musician effect: Does it persist under degraded pitch conditions of cochlear implant simulations?

Frontiers in Neuroscience, 2014
Cochlear implants (CIs) are auditory prostheses that restore hearing via electrical stimulation of the auditory nerve. Compared to normal acoustic hearing, sounds transmitted through the CI are spectro-temporally degraded, causing difficulties in ...

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

Advanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Perception of the acoustic properties of Serbian lexical pitch accents

Estudios de Fonética Experimental
In this study, we explored to what extent native speakers of Serbian are perceptually sensitive to the acoustic properties of Serbian lexical pitch accents—namely pitch and length—and how accurately they distinguish between different lexical pitch ...

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance

Advanced Science, EarlyView.
DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

Pitch perception of focus and surprise in Mandarin Chinese: Evidence for parallel encoding via additive division of pitch range [PDF]

, 2016
This study addressed the question of how multiple layers of meanings can be simultaneously encoded with F0 in speech by assessing pitch perception thresholds of focus and surprise in Mandarin Chinese.

Individual variation in suprasegmental perception: insights from adults with typical hearing and cochlear implants

Frontiers in Psychology
Individuals vary in their ability to perceive suprasegmental cues, such as pitch, intensity, and duration, to make linguistic and nonlinguistic judgments, such as lexical stress, intonation, talker identity, and vocal emotion perception.

A perceptual pitch boundary in a non-human primate

Frontiers in Psychology, 2014
Pitch is an auditory percept critical to the perception of music and speech, and for these harmonic sounds, pitch is closely related to the repetition rate of the acoustic wave.
