Summary
Our brains can change their minds by updating intentions when goals become too costly. This involves dynamic neural representations in the fronto-parietal cortex, balancing adaptation and goal pursuit.
Area of Science:
- Neuroscience
- Cognitive Science
- Decision Making
Background:
- Voluntary actions require flexible intentions, allowing goal pursuit or abandonment based on changing costs.
- Adapting intentions is crucial for navigating dynamic environments and optimizing goal achievement.
Purpose of the Study:
- To investigate the neural dynamics of changing one's mind after an action has begun.
- To identify brain regions involved in updating intentions based on new information.
Main Methods:
- Functional magnetic resonance imaging (fMRI) to observe brain activity.
- Multivariate pattern analysis (MVPA) to decode neural representations of choices.
- Examining neural changes in response to externally cued rewards/costs and endogenous decision updates.
Main Results:
- Visual cortex representations of initial choices remained stable.
- Fronto-parietal cortex (including precuneus, angular gyrus, dorsolateral prefrontal cortex) showed dynamic representations reflecting updated decision-making.
- Medial frontal cortex activity predicted mind changes independent of external cues.
- Increased fronto-parietal functional connectivity was observed during mind changes.
Conclusions:
- Neural representations in the fronto-parietal cortex dynamically update intentions based on new information.
- The brain balances adapting to environmental changes with pursuing internal goals through flexible intention updating.

11.4K
This protocol presents a novel methodology for the neural decoding of intent from freely-behaving infants during unscripted social interaction with an actor. Neural activity is acquired using non-invasive high-density active scalp electroencephalography (EEG). Kinematic data is collected with inertial measurement units and supplemented with synchronized video recording.

Children are not the best artists. Sometimes it’s easy to pick out the characteristic triangular head, whiskers, and tail of a cat, but children often describe elaborate scenarios that they depict as a beautifully unrecognizable mess. Thus, given children’s questionable artistic talent, how do they know what their drawings, and the drawings of others, represent? One way children identify...

Two key frameworks are employed to analyze mass, energy, and momentum transfer: the control volume approach and the system approach. These frameworks offer different perspectives, depending on whether the focus is on a specific region in space (control volume approach) or a defined mass of fluid (system approach).
The control volume approach considers a stationary region in space through which fluid flows. This region is bounded by a control surface. For instance, in the case of water...

Imagine the sound of a bell ringing. What is happening in the brain when we conjure up a sound like this in the "mind's ear?" There is growing evidence that the brain uses the same mechanisms for imagination that it uses for perception.1 For example, when imagining visual images, the visual cortex becomes activated, and when imagining sounds, the auditory cortex is engaged. However, to what...

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
