Topic: amygdala neurons

Primate amygdala neuron process the value of visual stimuli to guide decision-making and social interactions (Grabenhorst et al., 2019; Grabenhorst et al., 2023). However, it remains unclear whether different amygdala neurons are sensitive to distinct value components, such as reward probability and magnitude, and whether they integrate these components to decision variables, including risk and expected value. To address these questions, we recorded activity of amygdala neurons while monkeys viewed sequentially presented stimuli that provided separate information about the probability, magnitu

Nutrients and oral-sensory food qualities influence the subjective valuation of food. We recently showed that monkeys prefer sugar- and fat-rich foods, consistent with the integration of nutrient and oral-sensory properties into economic values to guide choice (Huang et al., 2021) and reinforcement learning (Huang & Grabenhorst, 2023). However, it is unclear how amygdala neurons, which encode subjective values during economic choice (Grabenhorst et al., 2012, Jezzini & Padoa-Schioppa, 2020), process nutrients and oral-sensory food attributes during choice. Here, we recorded the activit
