Summary: According to research, the human brain’s cells can understand the number zero as a numerical value rather than just as a “nothing.” Researchers used microelectrodes to track neurosurgical patient mental activity and discover nerve cells that particularly responded zero.
This research reveals how the mind incorporates the quantity line along with other quantifiable values. The results provide fresh insights into the neuronal foundation of quantitative consciousness.
Important Information:
- Zero is recognized as a numerical value by synapses in the medial temporal lobes.
- Zero is integrated into the mind’s range line, distinct from other figures.
- The mental processes zero by using symbols like Arabic letters.

The cerebral foundation of the amount zero in the human mind was previously unknown despite its significance for mathematics.
Researchers from the University Hospital Bonn ( UKB), the University of Bonn, and the University of Tübingen have now discovered that each individual nerve cell in the medial temporal lobe recognizes zero as a numerical value and not as a distinct category of “nothing.”
The findings have just been released in the book” Present Biology.”
The development of number systems and mathematics has been influenced by the concept of the range zero, which is commonly regarded as one of humankind’s most significant historical efforts.
Zero, according to co-author Prof. Florian Mormann from the UKB, who is also a member of the Transdisciplinary Research Area ( TRA )” Life &, Health” at the University of Bonn, means the absence of something countable and at the same time as having a numerical value, unlike other numbers like one, two, or three, which represent countable quantities.
The idea of the number zero just came about recently in human history, over the past two millennia, in contrast to beneficial natural numbers. This is also true for early advancement, as children are usually only able to comprehend the concept of zero and its related mathematical rules at around the age of six.
The amount zero is sent by neurons.
How nerve cells in the human mind represent this idea has not yet been studied. To get to the bottom of this conundrum, the researchers from Bonn have then collaborated with neurobiologists from the University of Tübingen.
In order to accomplish this, they displayed numeric values for neurosurgical people who had hair-thin microelectrodes inserted into their historical lobe before having surgery at the UKB. On one hand, the numeric values were displayed as Arabic letters, along with a set of clear dots.
The study’s first artist, Esther Kutter, claims that we were able to track down individual nerve cells and identify neurons that were able to detect zero.
The Arabic numerical zero or the empty fixed did not cause for cells to respond to sometimes, but they did no.
Number zero represents a neuronal numeric value.
In both scenarios, there was a numerical range effect in which cells reacted weaker, but substantially, also to the neighboring range one.
” So at the synaptic level, the concept of low is not encoded as a separate group” nothing”, but as a numerical value integrated with another, quantifiable numerical values at the lower end of the range line”, says Prof. Dr. Andreas Nieder from the Institute of Neurobiology at the University of Tübingen.
Prof. Mormann adds:” Despite this connectivity, the empty collection is encoded differently from other numbers at the synaptic community level, especially in the case of level sets. This might explain why the cognitive level of the vacant set’s recognition also takes more than the other small numbers’.
For Arabic letters, but, this result was never found at either the neuronal or behavioral level. The researchers now understand how crucial symbolic representations, such as Arabic numerals, are for the inclusion of the number zero on the amount collection in the human brain.
The German Research Foundation DFG provided cash for the research through the goal plan SPP 2205.

The single-neuron representation of the nonsymbolic and metaphorical range zero in the human lateral and temporal lobe was written by Florian Mormann and colleagues. Recent Biology
Abstract
In the animal medial temporal lobes, the nonsymbolic and symbolic quantity zero is represented by a single neuron.
Zero has a special place among numbers, making it essential to develop a thorough range concept.  , Despite its importance in calculus, the cerebral base of zero in the human mind is unknown.
We conducted single-neuron recordings in neurosurgical patients  , while they made judgments involving nonsymbolic number representations ( dot numerosity ), including the empty set, and symbolic numbers ( Arabic numerals ), including numeral zero. However, none of the two showed responsiveness when compared to the bare fixed and the number zero.
At the lower ending of the number line, zero representations are integrated with quantifiable numerosities and good integers, indicating that there is a quantitative distance effect when neurons are nullified in both symbolic and nonsymbolic formats.
Between the nonsymbolic bare set and small numerosities, there was a boundary in synaptic coding that was related to the relative difficulty of distinguishing numerosity zero socially.
No such limit for symbolic zero action was discovered in contrast, suggesting that symbolic representations combine zero with additional numerals along the range line to reconcile its outcast role.
The activity of neurons in the human brain, which appear to serve as a framework for more sophisticated representations of zero as a symbolic number, shows how special nonsymbolic numerical quantity is treated as a scaffold for the development of more sophisticated representations of the number.
