The salience network dynamics in perceptual decision-making
Recent neuroimaging studies have demonstrated that the network consisting of the right anterior insula (rAI), left anterior insula (lAI) and dorsal anterior cingulate cortex (dACC) is activated in sensory stimulus-guided goal-directed behaviors. This network is often known as the salience network (SN). When and how a sensory signal enters and organizes within SN before reaching the central exec...
متن کاملOscillatory Network Dynamics in Perceptual Decision-Making
Synchronized oscillations of ensembles of neurons in the brain underlie human cognition and behaviors. Neuronal network oscillations can be described by the physics of coupled dynamical systems. This dissertation examines the dynamic network activities in two distinct neurocognitive networks, the salience network (SN) and the ventral temporal cortex-dorsolateral prefrontal cortex (VTC-DLPFC) ne...
متن کاملNeural Stochastic Dynamics of Perceptual Decision Making
Recent studies have identified some brain regions involved in the decision process for simple perceptual tasks, and have provided insight into how sensory information is evaluated before the commitment to a motor response. To understand the dynamical principles of the decision process, and how they emerge from the interaction of interconnected neurons, computational models have been proposed ba...
متن کاملCortical Network Dynamics of Perceptual Decision-Making in the Human Brain
Goal-directed behavior requires the flexible transformation of sensory evidence about our environment into motor actions. Studies of perceptual decision-making have shown that this transformation is distributed across several widely separated brain regions. Yet, little is known about how decision-making emerges from the dynamic interactions among these regions. Here, we review a series of studi...
متن کاملSalience Network Activity in Perceptual Decisions
The dorsal anterior cingulate cortex (dACC) and the anterior insulae (AIs) are coactivated in various perceptual decision-making (PDM) tasks and form the salience network (SN): a key network in sensory perception and the coordination of behavioral responses. However, what the functional role of SN is, how these key SN nodes interact with each other to form a network in a perceptual decision, an...
