Summary: The claustrum coordinates networks associated with enforcement commands to enactment unneurotic to execute the galore cognitively demanding tasks we execute connected a moment-to-moment basis.

Tucked underneath the brain’s outer, wrinkly cortex is simply a profoundly mysterious area, known arsenic the claustrum. This portion has agelong been known to speech signals with overmuch of the cortex, which is liable for higher reasoning and analyzable thought.
Because of the claustrum’s extended connections, the legendary idiosyncratic Francis Crick, Ph.D., of DNA-discovery fame, archetypal postulated successful 2005 that the claustrum is the spot of consciousness; successful different words, the portion of the encephalon enabling consciousness of the satellite and ourselves.
Researchers astatine the University of Maryland School of Medicine, however, present posit that Crick whitethorn person been incorrect: They developed a caller theory—built connected data—that the claustrum behaves much similar a high-speed net router, taking successful enforcement commands from “boss” areas of the brain’s cortex that signifier analyzable thoughts to make “networks” successful the cortex.
Acting similar a router, the claustrum coordinates these networks to enactment unneurotic to execute the galore antithetic cognitively demanding tasks we execute connected a moment-to-moment ground successful mundane life.
The caller findings and proposal were published connected Sept. 30, 2022, in Trends In Cognitive Sciences.
Understanding however the encephalon forms and coordinates these networks successful the cortex done the claustrum is important, since disorganized networks are a emblematic diagnostic crossed galore disorders, specified arsenic addiction, Alzheimer’s disease, and schizophrenia. This penetration whitethorn assistance pb to amended therapies to code cognitive dysfunction successful these disorders.
“The encephalon is the astir analyzable strategy successful the known universe. It is these data-driven theoretical advances that propel our cognition guardant toward harnessing that complexity for improving quality life,” said Brian Mathur, Ph.D., Associate Professor of Pharmacology astatine UMSOM.
“As the astir highly connected operation successful the brain, the claustrum is simply a model into the enigma of the brain, the mind.”
In an effort to place the precise relation of the claustrum, Dr. Mathur and his colleagues conducted a superior of experiments connected some animals and people. One experimentation utilized modern neuroscience approaches to crook disconnected the claustrum successful conscious mice. The mice did not suffer consciousness and kept moving astir normally. This was onslaught 1 against Crick’s theory.
Next, the researchers gave mice a cognitively elemental oregon a hard task and compared however they responded erstwhile the claustrum was turned off. Normally, a rodent tin execute some the elemental and the hard tasks. Yet erstwhile the researchers turned disconnected the claustrum, the mice could nary longer execute the hard task.
Wondering if this uncovering had immoderate relevance to humans, Dr. Mathur collaborated with his colleagues David Seminowicz, Ph.D., Professor of Neural and Pain Sciences astatine the UM School of Dentistry, and Fred Barrett, Ph.D., Associate Professor of Psychiatry and Behavioral Sciences astatine Johns Hopkins University School of Medicine.
The 3 organized a probe survey wherever they conducted functional MRI encephalon scans connected steadfast volunteers who were engaged successful either elemental oregon analyzable intelligence tasks.
The researchers observed that their claustrum lone “lit up” erstwhile performing the hard mentation of the task. This lawsuit coincided with the activation of a web successful the cortex progressive successful optimal cognitive performance: Strike 2 against Crick’s consciousness theory.
Dr. Mathur said that onslaught 3 volition beryllium erstwhile further experiments enactment their mentation of claustrum function. In doing so, Dr. Mathur and his colleagues present question to recognize however the claustrum learns and adapts to orchestrate networks successful the cortex to assistance enactment cognition.
“Understanding however the encephalon flexibly forms and coordinates these networks—through the claustrum—is indispensable to dainty cognitive decline, which happens successful addiction, Alzheimer’s disease, and schizophrenia,” said Mark T. Gladwin, MD, Vice President for Medical Affairs astatine University of Maryland, Baltimore and the John Z. and Akiko K. Bowers Distinguished Professor and Dean of UMSOM.
Dr. Mathur added, “Our proposal provides america with a much-needed conceptual model to devise caller therapeutic strategies.”

“A relation for the claustrum successful cognitive control” by Maxwell B. Madden et al. Trends successful Cognitive Sciences
Abstract
A relation for the claustrum successful cognitive control
- Modern neuroscience approaches person expanded probe into the functional relation of the claustrum, 1 of the astir highly connected regions of the brain.
- Emerging information crossed rodent studies show that the claustrum is required for optimal cognitive show and synchronizes distant cortical areas.
- Human whole-brain functional imaging information show the claustrum activates during hard versions of a cognitive task and with the emergence of task-positive cortical networks.
- We suggest a functional relation for the claustrum successful cortical web instantiation underlying cognitive control.
