executive system
(noun)
The network that regulates the processes of executive function.
Examples of executive system in the following topics:
-
Executive Function and Control
- The executive system is a theoretical cognitive system that manages the processes of executive function.
- There are five types of situation where routine behavior is insufficient for optimal performance, in which the executive system comes into play:
- But if this behavior conflicts with internal plans (such as a diet), the executive system might be engaged to inhibit that response.
- The abilities of the executive system mature at different rates over time because the brain continues to mature and develop connections well into adulthood.
- During early adulthood (from ages 20 to 29) executive functions are at their peak, but in later adulthood these systems begin to decline.
-
Describing Consciousness
- It has also been defined in the following ways: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive-control system of the mind.
- Higher brain areas are more widely accepted as necessary for consciousness to occur, especially the prefrontal cortex, which is involved in a range of higher cognitive functions collectively known as executive functions.
-
Short-Term and Working Memory
- According to Baddeley, working memory has a phonological loop to preserve verbal data, a visuospatial scratchpad to control visual data, and a central executive to disperse attention between them.
- We could roughly say that it is a system specialized for language.
- The phonological loop and visuospatial sketchpad are semi-independent systems; because of this, you can increase the amount you can remember by engaging both systems at once.
- The central executive connects the phonological loop and the visuospatial sketchpad and coordinates their activities.
- The limbic system of the brain (including the hippocampus and amygdala) is not necessarily directly involved in long-term memory, but it selects particular information from short-term memory and consolidates these memories by playing them like a continuous tape.
-
The Limbic System
- The limbic system combines higher mental functions and primitive emotion into one system.
- It combines higher mental functions and primitive emotion into a single system often referred to as the emotional nervous system.
- There are several important structures within the limbic system: the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.
- The basal ganglia appears to serve as a gating mechanism for physical movements, inhibiting potential movements until they are fully appropriate for the circumstances in which they are to be executed.
- All the components of the limbic system work together to regulate some of the brain's most important processes.
-
Cerebral Hemispheres and Lobes of the Brain
- The frontal lobe is associated with executive functions and motor performance.
- Executive functions are some of the highest-order cognitive processes that humans have.
- It also plays an important role in retaining emotional memories derived from the limbic system, and modifying those emotions to fit socially accepted norms.
- The parietal lobe is comprised of the somatosensory cortex and part of the visual system.
-
Neural Underpinnings of Consciousness
- The physical world is perceived by human consciousness through the senses, which funnel stimuli and information into the central nervous system, and eventually the brain.
- In this context, the neuronal correlates of consciousness may be viewed as its causes, and consciousness may be thought of as a state-dependent property of some complex, adaptive, and highly interconnected biological system.
- Higher brain areas are seen as more promising, especially the prefrontal cortex, which is involved in a range of executive (higher-order) functions.

Introduction to the Nervous System
- The basic unit of the nervous system is the neuron.
- The nervous system can be divided into two major parts—the central nervous system (CNS) and the peripheral nervous system (PNS).
- The peripheral nervous system includes a large system of nerves that are linked to the brain and spinal cord.
- The PNS can be further subdivided into the autonomic nervous system and the somatic nervous system.
- The nervous system of the human body, including the brain and spinal cord (central nervous system) and all the nerves of the body (peripheral nervous system).
-
Introduction to Schizophrenia and Psychosis
- These include poor ability to absorb and act upon information (executive functioning), lack of attention, and an inability to utilize working memory.
- Family therapy or education, which addresses the whole family system of an individual, may reduce relapses and hospitalizations.
-
Early Roots of Psychology
- They argued that all human experiences are physical processes occurring within the brain and nervous system.
- In functionalism, the brain is believed to have evolved for the purpose of bettering the survival chances of its carrier by acting as an information processor: its role is essentially to execute functions similar to the way a computer does.
