Summary: Anxiety is characterized by anxious anticipation and heightened vigilance to uncertain threat. Context conditioning can experimentally induce anxiety, and dynamic sensory input from video presentation disrupts the visuocortical signal, particularly for motivationally significant and threatening contexts.

Summary: This study investigated the relationship between age and high-frequency oscillations (HFOs), and found that the age effect on HFO rates could not be replicated in scalp-EEG recordings. This lack of replicability may be due to the local propagation patterns of age-related HFOs occurring only in deep structures. Limitations such as small sample size, decreased signal-to-noise ratio compared to invasive recordings, and HFO-mimicking artifacts should be considered.

Summary: Occipital oscillations in the alpha band play a crucial role in visual perception and attention, affecting the detection of challenging visual stimuli. The phase of alpha oscillations prior to stimulus onset is critical for visual stimulus detection. Longer presentation times may attenuate response bias and lead to increased perceptual accuracy.

Summary: Human learning may depend on the evaluation of the outcomes of our actions aligning with expectations, with EEG being used to study the neural signatures of feedback processing. While there is vast literature on the neural correlates of feedback processing, there are still methodological discrepancies and differences in results across studies.

Summary: Neural oscillations, particularly in the posterior alpha frequency band, play a crucial role in regulating information flow during visual processing. By experimentally modulating the intrinsic alpha frequency, this study found that rhythmic stimulation at the intrinsic alpha frequency induced increased cortical alpha phase coherency and functional connectivity in the visual and parietal areas, supporting the role of alpha oscillation in gating information flow during visual processing.

Summary: This paper systematically investigates the plasma extraction transit time (PETT) oscillations in Press Pack IGBT (PPI) devices with multi-chips. It is first reported that there are multiple resonant oscillations during the turn-off process of multi-chips, and the oscillations overlap in the time domain waveforms, making PETT oscillation more serious in multi-chips. PETT oscillation is divided into three different feedback states for the first time. The physical and behavior models of the IGBT chip in the PETT oscillation are proposed, forming the equivalent circuit as a two-port network. It is indicated that only parallel resonances can lead to PETT oscillation, which is consistent with the experiment results.

Summary: The study found that neonatal seizures can co-occur with high-frequency oscillations (HFOs), but the relationship between them and outcome is not clear yet.

Summary: This study investigated the effects of eyes-closed and eyes-open conditions on EEG biomarkers for discriminating between major depressive disorder (MDD) and healthy control (HC) subjects. The findings showed that MDD subjects exhibited increased beta and gamma powers in both conditions compared to HC subjects. In the eyes-open condition, MDD subjects also showed increased complexity and scaling exponents in the alpha band. The best classification performance was achieved in the eyes-open condition, with a leave-one-out classification accuracy of 89.29%.

Summary: This study examines the impact of specific feature and channel combinations on predicting epileptic seizures in different patients. By selecting optimal features and channels based on the minimal-redundancy-maximal-relevance criterion, the trained models are able to effectively differentiate between pre-ictal and inter-ictal EEG signals. The detailed list of optimal features and summarized features provided in the study can serve as a reference for future research on this topic.

Summary: It is remarkable how human listeners can perceive periodicity in noise, which lacks obvious physical cues. Previous research suggested that listeners rely on short temporally local and idiosyncratic features to perceptually segment periodic noise sequences. The present study aimed to examine the consistency of perceptual segmentation within and between listeners. Results showed that the consistency was stronger for interleaved periodic sequences, likely due to reduced temporal jitter. Additionally, the finding that certain noise sequences were segmented consistently across listeners challenges the assumption that the features are necessarily idiosyncratic.

Summary: Visual categorization is the brain's ability to respond rapidly to certain category of inputs, and it might be influenced by odors. The experiment found that odor can enhance the response to ambiguous face-like objects, but it has no significant effect on other category-selective responses or general visual response. These findings suggest that the brain actively uses cues from different senses to categorize visual inputs, and olfaction can disambiguate visual information effectively.

Summary: Low-cost amplifiers have potential for measuring stimulus-induced narrow-band gamma oscillations, despite introducing more noise compared to high-cost amplifiers. Results showed that the spectral and temporal features of these responses were highly correlated between the low-cost and high-cost amplifiers, suggesting that low-cost amplifiers can be used for measuring gamma responses.

Summary: This study examines the development of dominant rhythm frequency in infants during a sustained attention task. The results show that the peak frequency increases from 6 to 9 to 12 months of age in response to faces and objects. The center of gravity (CoG) is found to be a robust index of brain development in infancy.

Summary: The study found that Gaussian curves require less contrast compared to Gabor and grating patterns to achieve equal perceived salience, and bluish Gaussians have higher salience than yellowish Gaussians at equal levels of contrast. Additionally, reducing the proportion of lowpass non-flat contrast distribution in the stimulus can decrease the blue/yellow asymmetry, with minimal asymmetry observed for stimuli with flat contrast distribution.

Summary: This study examined the brain's response to different types of errors by observing feedback-related EEG activity. The results revealed that selection errors elicited a larger feedback-related negativity (FRN) and were correlated with behavioral adjustment, while execution errors produced a different pattern of FRN and error positivity, which were not correlated with subsequent changes in behavior.

Summary: This study investigated the influence of pattern figurality and color on symmetry perception. By comparing wedge and dot patterns in younger and older adults, it was found that attention to color had a greater effect on segregated wedge patterns, with older adults performing worse than younger adults. However, their performance improved significantly through color cueing.

Summary: The concept of colour opponency suggests that colour vision is based on the comparison of two chromatic mechanisms: red versus green and yellow versus blue. Unique hues, including red, green, blue, and yellow, are assumed to correspond to the null points of these chromatic systems. This study demonstrates that electroencephalographic responses carry robust information about tested unique hues within a specific timeframe. The efficiency of hue decoding is influenced by luminance contrast and perceptual neighbourhoods.

Summary: The current study examines how the human brain handles distraction by salient stimuli and challenges the idea of proactive suppression by proposing an alternative mechanism called global target-feature enhancement. Through various experiments, the study demonstrates that the observed effects can be better explained by this alternative mechanism rather than proactive distractor suppression.
