Genetic Dissection of Neural Circuits Underlying Value Based Decision Making
<p>Decision making is the fundamental process that we utilize to accomplish objectives in everyday lives. To understand the neural substrates of this process, we developed a behavioral task for mice that required repetition of the processes of action initiation, action selection, and learning. The …

Pharmacological and Genetic Effects of Serotonin on Value-Based Decision-Making
… the neuromodulator serotonin on four different value-based decision making tasks, using an acute tryptopahin intervention and an associative genetic approach - a naturally occuring variation in the promoter region of the serotonin transporter gene (5-HTTLPR). Additionally, structural (DTI) and …

Neighbourhood Level Master-Planning - ‘A Strategic Value-Based Decision-Making Perspective’
… little is said about stakeholders’ susceptible values and actions tied to dominate sources of complex urban development pressures. In that context, this research aims to explore the significance of ‘value’ in master-planning at the residential neighbourhood and the pre-application planning phase …

Interactions Between Medical Prefrontal Cortex, Orbitofrontal Cortex and Motor Cortex in Value-based Decision Making
… of rodent prefrontal cortex contribute to value-based decision making, by comparing neural signals related to animal’s choice, its outcome, and action value in orbitofrontal cortex (OFC) and medial prefrontal cortex (mPFC) of rats performing a dynamic two-armed bandit (TAB) task. And we …

Foundations for Improved Models of Value-Based Decision-Making: Neural Correlates in the Anterior Cingulate Cortex and their Implications
How do we choose between different options based on their value? Conceptual frameworks of value-based choice describe the process in several stages, often (though not always) with the assumption that these stages are serial, discrete, and localized to different brain regions. Moreover, while …

Unveiling the ESG Landscape: Exploring Revealed Preferences through Archetypal Analysis of Decision-Makers in Environmental, Social, and Governance Causes
This research investigates the motivations and decision-making patterns driving individuals' behavior when giving to Environmental, Social, and Governance (ESG) causes. Through the concept of revealed preferences, this study offers a comprehensive exploration of the intricate landscape of ESG …

Computational Modeling of Multi-Agent, Continuous Decision Making in Competitive Contexts
<p>Humans are able to make adaptive decisions with the goal of obtaining a goal, earning a reward, or avoiding punishment. While much is known about the behavior and corresponding underlying neural mechanism relating to this aspect of decision-making, the field of cognitive neuroscience has focused …

Neural basis of private and social decision-making: new insights from transcranial ultrasound stimulation and multivariate analysis
Value-based decision-making is a complex process that requires the integration of many pieces of information, or decision variables, to choose among several options. These decision variables include the expected value of an option, its associated risk, or the anticipation of the emotions that one …

The Neural Computations In The Caudate Nucleus For Reward-Biased Perceptual Decision-Making
Decision-making is a complex process in which our brain has to combine different sources of information, such as noisy sensory evidence and expected reward, in appropriate ways to obtain the outcome that satisfies the decision-maker. Despite various studies on perceptual decision-making and …

Probing the Mechanisms of Reinforcement Learning: Reinforcement Learning, Ventral Striatal Astrocytes, and the Dynamic Coordination of Information Seeking with Learning
… and animal brain have been known to support value-based decision-making and reinforcement learning in the brain [222, 131, 7]. However, to date, the role of astrocytes in reinforcement learning has not been thoroughly studied. Here, we trained mice on a bandit task, and attenuated the …

Computational modeling of health decision-making
Value-based decision making consists of weighting stimulus attributes to compute stimulus value and guides choice such that the stimulus with highest value is chosen. While successful in maximizing value in the short-term, this does not always lead to long-term advantageous choices. Incorporating …

The Pragmatics of Confidence in Perceptual and Value-based Choice
… report a subjective sense of confidence in a decision before knowing its outcome. Such confidence judgements are positively correlated to accuracy in perceptual and memory tasks, but the strength of this relationship (known as metacognitive accuracy) differs across people and contexts. …

Getting a monkey to do your bidding: Developing a Becker-DeGroot-Marschak (BDM) method for use in monkeys
… more recently, in neuroimaging studies of human decision making. The BDM has never been used with animal subjects before, yet its application in monkeys would allow for comparison of studies across species while providing a direct measure of what a reward is worth to a monkey in a single …
