Neural signatures of automatic repetition detection in temporally regular and jittered acoustic sequences.

Detection of repeating patterns within continuous sound streams is crucial for efficient auditory perception. Previous studies demonstrated a remarkable sensitivity of the human auditory system to periodic repetitions in unfamiliar, meaningless sounds. Automatic repetition detection was reflected in different EEG markers, including sustained activity, neural synchronisation, and event-related responses to pattern occurrences.

Application of a mathematical framework for the optimization of precision-fed dairy cattle diets.

Applied tools that allow more precise feeding of animals provide an opportunity to maximize revenue under milk and feed price oscillations. A compact-vectorized version of the 8th revised edition of Nutrient Requirements of Dairy Cattle model was developed to optimize rations for maximum profit by utilizing non-linear programming with linear and non-linear constraints. This study aimed to (1) evaluate feed cost and milk income minus feed cost (IOFC) if individual diets (IND) could be fed, (2) evaluate feed cost and IOFC when deriving three optimal partial mixed diets for group feeding in three pens (fresh, high, and low production) and two optimal grain mixes to be fed individually via auto-feeders (CLU), and (3) briefly compare optimized solutions across pen-averages.

That sounds awful! Does sound unpleasantness modulate the mismatch negativity and its habituation?

There are sounds that most people perceive as highly unpleasant, for instance, the sound of rubbing pieces of polystyrene together. Previous research showed larger physiological and neural responses for such aversive compared to neutral sounds. Hitherto, it remains unclear whether habituation, i.

Perceptual learning of random acoustic patterns: Impact of temporal regularity and attention.

Perceptual learning is a powerful mechanism to enhance perceptual abilities and to form robust memory representations of previously unfamiliar sounds. Memory formation through repeated exposure takes place even for random and complex acoustic patterns devoid of semantic content. The current study sought to scrutinise how perceptual learning of random acoustic patterns is shaped by two potential modulators: temporal regularity of pattern repetition and listeners' attention.

Within- and between-subject consistency of perceptual segmentation in periodic noise: A combined behavioral tapping and EEG study.

It is remarkable that human listeners can perceive periodicity in noise, as the isochronous repetition of a particular noise segment is not accompanied by salient physical cues in the acoustic signal. Previous research suggested that listeners rely on short temporally local and idiosyncratic features to perceptually segment periodic noise sequences. The present study sought to test this assumption by disentangling consistency of perceptual segmentation within and between listeners.
