Summary
The cerebellum and associated pathways, not just the anterior cingulate cortex, play a key role in cognitive control and adjusting behavior after errors. This study reveals new information flow in the brain during error processing.
Area of Science:
- Neuroscience
- Cognitive Neuroscience
- Neuroimaging
Background:
- Cognitive control involves error detection and behavioral adjustment.
- The anterior cingulate cortex (ACC) is traditionally viewed as central to these functions.
- Previous research linked dorsal ACC and subcortical activity to error detection, and ventrolateral prefrontal cortex (VLPFC) activity to post-error slowing (PES).
Purpose of the Study:
- To investigate the causal relationships between brain regions during error processing and behavioral adjustment.
- To identify the neural sources that drive VLPFC activation during PES.
- To elucidate the role of the cerebello-thalamo-cortical pathway in cognitive control.
Main Methods:
- Functional magnetic resonance imaging (fMRI) was used in 54 adults performing a stop-signal task (SST).
- Granger causality mapping (GCM) was employed to analyze directed information flow between brain regions.
- Multivariate Granger causal analysis (GCA) was utilized to map information flow across the network.
Main Results:
- The supplementary motor area (SMA), cerebellum, pontine region, and medial thalamus were identified as regions Granger-causing VLPFC activation during PES.
- Error-related activity in these regions correlated with VLPFC activity during PES, with the cerebellum showing the strongest association.
- Cerebellar activation was found to Granger-cause prefrontal activity during behavioral adjustment.
Conclusions:
- The cerebellum plays a significant role in cognitive control and behavioral adjustment following errors.
- The cerebello-thalamo-cortical pathway is highlighted as crucial for executive functions.
- These findings challenge the traditional view by emphasizing the cerebellum's contribution to cognitive control, previously attributed mainly to the ACC-prefrontal circuit.

01:27Diencephalon: Thalamus and Information Relay
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological states or needs.
01:14Role of Cerebellum and Prefrontal Cortex in Memory
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
01:17Cerebellum: Anatomical Regions
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:14Motor and Sensory Areas of the Cortex
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

01:30Diencephalon: Anatomical Regions
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the subthalamic...
