TLDR
In this paper, the authors developed a novel informational connectivity method to test whether peri-frontal brain areas contribute to familiar face recognition and found that feed-forward flow dominates for the most familiar faces and top-down flow was only dominant when sensory evidence was insufficient to support face recognition.About:

Neural signatures of vigilance decrements predict behavioural errors before they occur.
TL;DR: In this paper, the authors designed a multiple-object monitoring paradigm to examine how the neural representation of information varied with target frequency and time performing the task and found that behavioural performance decreased over time for the rare target (monitoring) condition, but not for a frequent target (active) condition.

Concurrent neuroimaging and neurostimulation reveals a causal role for dlPFC in coding of task-relevant information.

TL;DR: In this article, the authors applied transcranial magnetic stimulation (TMS) during fMRI, and tested for causal changes in information coding, showing that TMS decreases coding of relevant information across frontoparietal cortex and the impact is significantly stronger than any effect on irrelevant information, which is not statistically detectable.

Evidence for a General Neural Signature of Face Familiarity.
TL;DR: This paper explored the neural signatures of face familiarity using cross-participant and cross-experiment decoding of event-related potentials, evoked by unknown and experimentally familiarized faces from a set of experiments with different participants, stimuli, and familiarization-types.
Journal ArticleDOI
A neural measure of the degree of face familiarity
TL;DR: In this paper , the authors measured face familiarity using subjective familiarity ratings in addition to testing explicit knowledge and reaction times in a face matching task, and found that the neural representations of familiar faces form part of a general neural signature of the familiarity component of recognition memory processes.

Codes-Temporal codes provide additional category-related information in object category decoding a systematic comparison of informative EEG features
TL;DR: Correlational analyses showed that the features which provided the most information about object categories, could predict participants’ performance (reaction time) more accurately than the less informative features.

TL;DR: It is found that intraflagellar transport 20 mediates the ability of Ror2 signaling to induce the invasiveness of tumors that lack primary cilia, and IFT20 regulates the nucleation of Golgi-derived microtubules by affecting the GM130-AKAP450 complex.

Distributed Hierarchical Processing in the Primate Cerebral Cortex
TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.
