High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

358
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Functional Brain Systems: Limbic System

3.5K
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...

Functional Brain Systems: Reticular Formation

2.4K
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...

Association Areas of the Cortex

6.0K
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,...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

559
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...

Cerebral Hemispheres01:05

Cerebral Hemispheres

457
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Summary

Balanced time perspective, the ability to adapt temporal focus, is supported by brain network interactions. Coordinated activity between the default mode network (DMN) and fronto-parietal network (FPN) is crucial for this cognitive flexibility.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Brain Imaging

Background:

  • Balanced time perspective involves adaptive switching between temporal foci.
  • The default mode network (DMN) is implicated in balanced time perspective.
  • The interaction between the DMN and fronto-parietal network (FPN) in supporting this ability remains unclear.

Purpose of the Study:

  • To investigate the neural underpinnings of balanced time perspective.
  • To examine the role of DMN and FPN functional connectivity in balanced time perspective.

Main Methods:

  • Resting-state functional magnetic resonance imaging (fMRI) was used.
  • 91 healthy participants (52 males, 39 females) completed a balanced time perspective questionnaire.
  • Seed-based voxel-wise functional connectivity analyses were performed.

Main Results:

  • Midline DMN regions (amPFC, PCC) and associated areas (ACC, precuneus, cerebellum) showed functional connectivity related to balanced time perspective.
  • Functional connectivity between the right anterior medial prefrontal cortex (amPFC) and right dorsal lateral prefrontal cortex (DLPFC) was significantly associated with balanced time perspective.

Conclusions:

  • Coordinated brain activity between DMN and FPN regions supports balanced time perspective.
  • The findings highlight the importance of inter-network communication for cognitive flexibility across time.
