Johnson S, Grabenhorst F
Front Neurosci
. 2025 Feb;
18:1517231.
PMID: 39911407
The successful pursuit of future rewards requires forming an internal goal, followed by planning, decision-making, and progress-tracking over multiple steps. The initial step-forming goals and the plans for obtaining them-involves...

J Neurosci
. 2024 Nov;
45(5).
PMID: 39592235
Risk is a fundamental factor affecting individual and social economic decisions, but its neural correlates are largely unexplored in the social domain. The amygdala, together with the dorsal anterior cingulate...

J Neurosci
. 2023 Oct;
43(47):8000-8017.
PMID: 37845034
Although overconsumption of high-fat foods is a major driver of weight gain, the neural mechanisms that link the oral sensory properties of dietary fat to reward valuation and eating behavior...

Grabenhorst F, Ponce-Alvarez A, Battaglia-Mayer A, Deco G, Schultz W
Neuron
. 2023 Sep;
111(23):3871-3884.e14.
PMID: 37725980
Primates make decisions visually by shifting their view from one object to the next, comparing values between objects, and choosing the best reward, even before acting. Here, we show that...

Woo J, Aguirre C, Bari B, Tsutsui K, Grabenhorst F, Cohen J, et al.
Cogn Affect Behav Neurosci
. 2023 Feb;
23(3):600-619.
PMID: 36823249
Despite being unpredictable and uncertain, reward environments often exhibit certain regularities, and animals navigating these environments try to detect and utilize such regularities to adapt their behavior. However, successful learning...

Huang F, Grabenhorst F
J Neurosci
. 2023 Jan;
43(10):1714-1730.
PMID: 36669886
In reinforcement learning (RL), animals choose by assigning values to options and learn by updating these values from reward outcomes. This framework has been instrumental in identifying fundamental learning variables...

Huang F, Sutcliffe M, Grabenhorst F
Proc Natl Acad Sci U S A
. 2021 Jun;
118(26).
PMID: 34155111
Value is a foundational concept in reinforcement learning and economic choice theory. In these frameworks, individuals choose by assigning values to objects and learn by updating values with experience. These...

Grabenhorst F, Schultz W
Behav Brain Res
. 2021 Apr;
409:113318.
PMID: 33901436
Long implicated in aversive processing, the amygdala is now recognized as a key component of the brain systems that process rewards. Beyond reward valuation, recent findings from single-neuron recordings in...

J Neurosci
. 2021 Feb;
41(13):3000-3013.
PMID: 33568490
Rewarding choice options typically contain multiple components, but neural signals in single brain voxels are scalar and primarily vary up or down. In a previous study, we had designed reward...
