High-Level and Low-Level Awareness

618
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...

Role of Cerebellum and Prefrontal Cortex in Memory

996
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...

Optimal Arousal Theory

723
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Organization of the Brain

2.3K
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Working Memory01:24

Working Memory

779
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Causes of Social Behavior II: Cognitive Processes

185
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Brain Imaging

Background:

  • Cognitive control is vital for daily functioning and can be impaired in neuropsychiatric disorders.
  • The claustrum, a subcortical structure, is hypothesized to support cognitive load by activating with cortical networks.
  • Understanding claustrum's role is key to deciphering cognitive impairments.

Purpose of the Study:

  • To investigate claustrum activation during cognitive control tasks.
  • To determine if the claustrum responds to varying cognitive demands.
  • To explore the claustrum's contribution to cognitive control networks.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was used to measure brain activity.
  • Fifty-five healthy participants completed four cognitive control tasks: Stroop, AX-CPT, task-switching, and Sternberg working memory.
  • Analysis focused on bilateral claustrum signals during task performance.

Main Results:

  • Bilateral claustrum activation was observed across all four cognitive control tasks.
  • Activation patterns correlated with increased cognitive load and specific trial phases.
  • Claustrum activity coincided with task-positive cortical network activations.

Conclusions:

  • The claustrum is actively involved in multiple cognitive control tasks.
  • Findings support the model of the claustrum supporting cortical demands during cognitive load.
  • This research may inform future studies on neuropsychiatric disorders impacting cognition.
