&NA; Preference judgment, the process of selecting a response from several alternatives based on which alternative the subject likes best, is an important aspect of daily life. The current study examined whether neural substrates that are thought to be critical for generating somatic markers are involved in preference judgments. Fifteen healthy, right‐handed subjects performed a preference judgment task during functional magnetic resonance imaging. The medial frontal gyrus was significantly… 

The role of ventromedial prefrontal cortex in decision making: judgment under uncertainty or judgment per se?

Ventromedial prefrontal cortex (VMF) is thought to be important in human decision making, but studies to date have focused on decision making under conditions of uncertainty, including risky or

Temporal isolation of neural processes underlying face preference decisions

The findings support a model in which rapid, automatic engagement of the NAC conveys a preference signal to the orbitofrontal cortex, which in turn is used to guide choice.

Neural representation of degree of preference in the medial prefrontal cortex

The observed activation patterns suggest possible valence–arousal dissociation among varying degrees of preference within the medial prefrontal cortex, reminiscent of the characterization of emotions along the axes of valence and arousal.

Ventromedial Frontal Lobe Damage Disrupts Value Maximization in Humans

A paradigm developed in experimental economics is used to empirically measure and quantify violations of utility theory in humans with damage to the ventromedial frontal lobe (VMF) and demonstrate that the VMF plays a critical role in value-maximizing choice.

Repetitive transcranial magnetic stimulation over the right dorsolateral prefrontal cortex decreases valuations during food choices

Using repetitive transcranial magnetic stimulation (rTMS) while subjects were involved in an economic valuation task involving the consumption of real foods found that application of rTMS to the right DLPFC caused a decrease in the values assigned to the stimuli.

The Cerebral Response during Subjective Choice with and without Self-reference

Results indicated greater activation in the AMPFC, RSC, and caudate nucleus during internal subjective decision-making, and suggest that self-referential processing, rather than subjective judgments among ambiguous response alternatives, accounted for the AMPs and RSC response.

How the Temporo-Parietal Cortex identifies Action Goals : The Mirror

The results suggest that inferring temporary states such as goals, intentions, and desires of other people—even when they are false and unjust from the authors' own perspective—strongly engages the temporo-parietal junction (TPJ) and the medial prefrontal cortex (mPFC).

Neural Response during Preference and Memory Judgments for Subliminally Presented Stimuli: A Functional Neuroimaging Study

The results suggest that hippocampal response to stimulus novelty can be independent of conscious reportability of familiarity, and activations of a memory system independent of recollective experience are demonstrated.

The insula is not specifically involved in disgust processing: an fMRI study

Findings do not fit the idea of the insula as a specific disgust processor, which is involved in the processing of visual stimuli depicting non-mimic disgust elicitors compared to fear-inducing and neutral scenes.

A neuromodulatory role for the human amygdala in processing emotional facial expressions.

Functional neuroimaging confirmed that the amygdala and some of its functionally connected structures mediate specific neural responses to fearful expressions and demonstrated that amygdalar responses predict expression-specific neural activity in extrastriate cortex.

Deciding Advantageously Before Knowing the Advantageous Strategy

The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does, and without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.

A Functional Anatomy of Anticipatory Anxiety

Findings support the role of paralimbic structures as neural substrates of anticipatory anxiety and the failure to demonstrate behavioral and neurophysiological changes with the distractor task may reflect the modest increases in anxiety with the shock, the relatively simple distractionor task, and small sample size.

Neuroanatomical substrata of amusement and sadness: a PET activation study using film stimuli

It appeared that many brain regions were involved similarly and symmetrically in both emotions, and bilateral activation of the amygdala in both target emotions was revealed.

The findings support the differential localization of the neural substrates of fear and disgust and suggest a possible general role for the perception of emotional expressions for the superior temporal gyrus.
