A Continuous Semantic Space Describes the Representation of Thousands of Object and Action Categories across the Human Brain

"Humans can recognize thousands of categories. Given the limited size of the human brain, it seems unreasonable to expect that every category is represented in a distinct brain area,”

says first author Alex Huth, a graduate student working in Dr. Jack Gallant’s laboratory at the University of California, Berkeley.

In a video diplayed at the web page of NEURON [link to the  article], the author reports how 

objects and action categories are organized within the brain according to a continuous  semantic space throughout the cortical surface.


Dr. A.P. Masucci (Research fellow at the Centre for Advanced Spatial Analysis CASA, University College of London.) defines [here] the semantic space as: 

 "the space of meaning, where the dynamics of meaning keep place. Where is it? It is in our heads!! Language is a collective phenomena and it resides in all our heads. As a natural phenomena language follows its natural laws and self-organises in structures and hierarchies."
