Orbitofrontal Cortex Uses Distinct Codes for Different Choice Attributes in Decisions Motivated by Curiosity
Extraversion and anterior vs. posterior DMN activity during self-referential thoughts
TLDR
It is hypothesized that in extraverts self-referential thoughts may be associated with an increase of spectral power in the posterior DMN hub, whereas in introverts they may beassociated with an increased of spectralPower in the anterior DMNHub.
Functional connectivity mapping of regions associated with self‐ and other‐processing
TLDR
Initial neurobiological evidence corroborating the increasing claims of an intricate self‐network is presented, the architecture of which may promote social value processing.
Insightful problem solving and emulation in brown capuchin monkeys
TLDR
It is indicated that capuchins do not spontaneously solve the floating object problem via insight, consistent with some previous results in great ape species and indicate that capuchin monkeys have limited capacity for insightful problem solving.

The Precuneus and Consciousness
TLDR
Findings suggest that the precuneus may play a central role in the neural network correlates of consciousness, and its activity seems to correlate with self-reflection processes, possibly involving mental imagery and episodic/autobiographical memory retrieval.
Curiosity in zoo animals.
The reactions of more than 200 zoo animals to a standardized set of novel objects were recorded and quantified. Our results indicated significant differences among various taxonomic groups, both in…

Prey capture efficiency in brown capuchin monkeys (Cebus apella) is influenced by sex and corpus callosum morphology
TLDR
The results suggest a relationship between prey capture efficiency, sex, and the degree of brain lateralization in capuchins is suggested.
Voxel-Based Morphometry—The Methods
At its simplest, voxel-based morphometry (VBM) involves a voxel-wise comparison of the local concentration of gray matter between two groups of subjects. The procedure is relatively straightforward…

Segmentation of brain MR images through a hidden Markov random field model and the expectation-maximization algorithm
TLDR
The authors propose a novel hidden Markov random field (HMRF) model, which is a stochastic process generated by a MRF whose state sequence cannot be observed directly but which can be indirectly estimated through observations.
Improved Optimization for the Robust and Accurate Linear Registration and Motion Correction of Brain Images
TLDR
This paper examines the optimization process in detail and demonstrates that the commonly used multiresolution local optimization methods can, and do, get trapped in local minima.
