Neural Mechanisms Underlying Human Consensus Decision-Making
Consensus building in a group is a hallmark of animal societies, yet little is known about its underlying computational and neural mechanisms. Here, we applied a computational framework to behavioral and fMRI data from human participants performing a consensus decision-making task with up to five other participants. We found that participants reached consensus decisions through integrating thei...
متن کاملBrain mechanisms for perceptual and reward-related decision-making.
Phenomenological models of decision-making, including the drift-diffusion and race models, are compared with mechanistic, biologically plausible models, such as integrate-and-fire attractor neuronal network models. The attractor network models show how decision confidence is an emergent property; and make testable predictions about the neural processes (including neuronal activity and fMRI sign...
متن کاملAnhedonia and anxiety underlying depressive symptomatology have distinct effects on reward-based decision-making
Depressive pathology, which includes both heightened negative affect (e.g., anxiety) and reduced positive affect (e.g., anhedonia), is known to be associated with sub-optimal decision-making, particularly in uncertain environments. Here, we use a computational approach to quantify and disambiguate how individual differences in these affective measures specifically relate to different aspects of...
متن کاملNeural mechanisms of risky decision-making and reward response in adolescent onset cannabis use disorder.
BACKGROUND Neural mechanisms of decision-making and reward response in adolescent cannabis use disorder (CUD) are underexplored. METHODS Three groups of male adolescents were studied: CUD in full remission (n=15); controls with psychopathology without substance use disorder history (n=23); and healthy controls (n=18). We investigated neural processing of decision-making and reward under condi...
متن کاملSensory initiation of a co‐ordinated motor response: synaptic excitation underlying simple decision‐making
KEY POINTS Deciding whether or how to initiate a motor response to a stimulus can be surprisingly slow and the underlying processes are not well understood. The neuronal circuitry that allows frog tadpoles to swim in response to touch is well characterized and includes excitatory reticulospinal neurons that drive swim circuit neurons. Build-up of excitation to reticulospinal neurons is the key ...
