This research has opened up exciting possibilities for understanding how the brain functions and has implications for future drug development and treatment of brain-related conditions.
Understanding the Semaphores of the Brain:
Lead author Sean Froudist-Walsh compares the brain to a city and the receptor patterns to traffic lights or semaphores that control the flow of information. By mapping the density of receptors for various neurotransmitter systems in more than 100 brain regions, the researchers were able to identify patterns in the arrangement of these “traffic lights.” This discovery provides valuable insights into the role of these receptors in perception, memory, and emotion. It offers a deeper understanding of how the normal brain works and may pave the way for targeting specific brain networks and functions with new drugs in the future.
The Power of Receptor Maps:
The research team utilized a technique called in vitro receptor autoradiography to create detailed receptor expression maps throughout the brain. They combined statistical techniques, modern neuroimaging, and anatomical knowledge to identify relationships between receptor patterns, brain connectivity, and anatomy. These maps have the potential to revolutionize our understanding of brain activity, behavior, and drug action. Furthermore, because receptors are the targets of drugs, this research could guide the development of new treatments that target specific brain functions.
Implications for Neuroscience and Future Research:
The detailed receptor maps created by the team provide a wealth of information that can be used by computational neuroscientists to develop elaborate models of the brain. These brain-inspired neural network models will help researchers unravel the mysteries of normal perception and memory, as well as investigate conditions such as schizophrenia or the effects of substances like “magic mushrooms.” The integration of findings across different species, from rodents to humans, holds promise for a better understanding of brain function at both circuit and large-scale levels.
Accelerating Translation Between Species:
Creating open-access receptor expression maps in the cortex and integrating them with neuroimaging data can accelerate the translation of research findings between species. This collaborative effort between the University of Bristol, New York University, the Human Brain Project, the Julich Research Center, the University of Düsseldorf, the Child Mind Institute, and the Université Paris Cite has not only made the data freely available to the scientific community but also aims to spark further research and the development of biologically informed models. This interdisciplinary approach has the potential to unlock new avenues of exploration and shed light on previously unknown aspects of brain functioning.

Receptor patterns define key organizing principles in the brain, scientists have discovered.
An international team of researchers studying the brains of macaques has mapped the neurotransmitter receptors, revealing a potential role in distinguishing internal thoughts and emotions from those generated by external influences.
The full data set has been made publicly available, serving as a bridge linking different scales of neuroscience, from the microscopic to the whole brain.
Lead author Sean Froudist-Walsh, from the University of Bristol’s Department of Computer Science, explained: “Imagine the brain as a city. In recent years, brain research has focused on studying its pathways, but In this research, we have made the most detailed map yet of the semaphores, the neurotransmitter receptors, that control the flow of information.
“We have discovered patterns in the arrangement of these ‘traffic lights’ that help us understand their role in perception, memory and emotion.
“It’s like finding the key to a city’s traffic flow, and it opens up exciting possibilities for understanding how the normal brain works.
“Potentially in the future, other researchers can use these maps to target particular brain networks and functions with new drugs.
“Our study aimed to create the most detailed map yet of these ‘traffic lights’.”
The team used a technique called in vitro receptor autoradiography to map the density of receptors for six different neurotransmitter systems in more than 100 brain regions.
To find the patterns in this large amount of data, they applied statistical techniques and used modern neuroimaging techniques, combined with expert anatomical knowledge. This allowed them to discover the relationships between receptor patterns, brain connectivity, and anatomy.
By understanding the organization of receptors throughout the brain, it is hoped that further studies can better link brain activity, behavior and drug action.
In addition, because receptors are the targets of drugs, the research could, in the future, guide the development of new treatments that target specific brain functions.
Froudist-Walsh added: “Next, we aim to use this data set to develop computational models of the brain.
“These brain-inspired neural network models will help us understand normal perception and memory, as well as differences in people with conditions such as schizophrenia or under the influence of substances such as ‘magic mushrooms.’
“We also plan to better integrate the findings across species, linking the detailed circuit-level neuroscience often carried out in rodents, with the large-scale brain activity seen in humans.”
Creation of open access receptor expression maps in the cortex that integrate neuroimaging data could accelerate translation between species.
“It is freely available to the neuroscientific community through the Human Brain Project’s EBRAINS infrastructure, so that they can be used by other computational neuroscientists with the aim of creating other biologically informed models,” added Nicola Palomero-Gallagher, HBP researcher at Forschungszentrum. Jülich. and main author of the article.
