Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

2.2K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Functional Brain Systems: Limbic System

3.4K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Association Areas of the Cortex

5.7K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Motor Control

Background:

  • Intentional action is crucial for goal-directed behavior, involving controlled motor acts.
  • Neuroimaging studies link self-generated actions to frontoparietal brain areas.
  • Functional connectivity within these frontoparietal regions during intentional action requires further investigation.

Purpose of the Study:

  • To investigate brain activations and functional connectivity during internally-generated versus externally-triggered actions.
  • To explore the role of frontoparietal and occipitotemporal regions in intentional action.
  • To compare neural efficiency between dominant and non-dominant hand use.

Main Methods:

  • Functional connectivity (FC) and brain activation analysis.
  • Thirty healthy participants performed a finger-pressing task with internally-generated or externally-triggered actions.
  • Task was performed with both dominant (right) and non-dominant (left) hands.

Main Results:

  • Internally-generated actions showed greater activation in posterior parietal and premotor cortex compared to externally-triggered actions.
  • Medial occipitotemporal regions, including lingual and fusiform gyri, were also engaged in internally-generated actions.
  • Increased functional coupling within frontoparietal networks and distinct coupling patterns in occipitotemporal regions were observed, indicating two segregated networks.
  • Dominant hand use exhibited less activation but stronger connectivity, suggesting enhanced neural efficiency.

Conclusions:

  • Two segregated networks, comprising frontoparietal and occipitotemporal cortex, independently contribute to intentional action.
  • Neural efficiency is enhanced when using the dominant hand, characterized by stronger functional connectivity.
  • Findings elucidate the distinct neural underpinnings of intentional motor control.
