In comparison to a human’s billions of neurons, ants have brains with about 250,000 neurons.
The ant colony’s brain is comparable in size to that of several animals. An ant’s brain is simple in comparison to a human’s, yet the colony as a whole may have feelings.
Compared to the human brain, which has more than 100 billion brain cells, scientists have even speculated that the whole colony may have feelings and are considered as the most intelligent insects. Ants have the greatest brain of any insect, according to experts.
Ant brains may all hunt for food, communicate, show mating signals, evade and confront opponents, and accomplish complicated navigation over long distances thanks to the hive mind rather than learning independently.
Humans do not have a genuine hive mind, since we do not experience the hive mind phenomenon as a collective experiencing the same thing at the same moment.

What is a brain?
The central nervous system of an animal includes a brain. It’s a collection of neurons involved in information processing, transmission, and reception to other body parts.
Brains, both in size and design, differ substantially between species. Several animals have ganglia scattered around the body that give them better control over appendages or regions of the body, but they are still connected to the main brain.
Corals, jellyfish, and oysters are among the animals known to have no brains. These creatures’ nerve clusters elsewhere in their bodies aid them sense and regulate their movements.
Do Ants Have Brains?
Ants have brains, albeit they are rather small. There are 250,000 neurons in the ant brain . Ants’ tiny minds manage to function on an incredible level of intelligence for invertebrates, despite their tiny six-legged bodies that may not compare to the size of our own brains with 100 billion neurons and 1000 trillion synapses (connections between cells).
One can’t help but be impressed by how hard these tiny ants labor, even if humans are many times more intelligent than they could ever be.
Ants, for example, are able to communicate with one another. Did you know this?
When necessary, ants may also escape from foes and fight them off. It’s amazing to watch how sophisticated their navigation abilities are when they’re hunting for food. They use visual hints to help them navigate around barriers and choose between different tasty desserts.
What is Intelligence?
Determining what intelligence is is one of the first obstacles in assessing any species’ intelligence. People frequently favor animals with comparable intelligence to their own. The language used has an impact on the definition.
Is it imitation or learning that’s going on? Is it using your brain to think and solve problems? Is it because we think in a certain way that we may underestimate it as humans?
While researching dolphin intelligence, Jill Richardson, a researcher at the University of Miami’s Rosenstiel School for Marine and Atmospheric Science, recalls the latter.
She claims that understanding intelligence may be a broader and more colorful experience than we commonly assume, based on her research into animal intelligence.
What Is Collective Intelligence?
Knowledge obtained from a community is known as collective intelligence. It’s when individuals come together to produce information that no one could get on their own.
The MIT Center for Collective Intelligence was founded by the Massachusetts Institute of Technology to investigate how people and computers may be linked so that they work more intelligently than anybody, group, or computer has ever done before.
Do ants have big brains compared to their body size?
In ants, the body-to-brain ratio is quite low, which is useful for comparing encephalization in this or related species. The brain to body ratio of an ant is roughly 1:7.
Ants with brains equivalent to roughly 15% of their total body weight were discovered, but they were smaller than predicted by an overall allometric ratio of brain to body size. Ants have incredibly strong brains despite the fact that they are not particularly massive.
Individual ants may not be very good, yet colonies of ants can achieve amazing things. Humans appear hazy to them because they have poor eyesight.
How Do Ant Brains Work?
The whole colony’s collective intelligence functions as one big highly functioning brain, with ant brains functioning more like human neurons.
All significant day-to-day choices inside the ant colony are made in unison and each ant understands their function, but there is no one dominant lead ant who controls the whole colony.
The queen only leaves the colony to lay eggs, and she doesn’t give any instructions about what happens inside.
The ant colonies are comparable to the human brain, according to Stanford researchers, since each neuron performs only basic operations but the activity of these tiny neurons allows the whole organism to operate. As a result, the brain can think on its own while none of the neurons can.
Like a pseudo-brain that can make complex decisions on its own without the individual ants understanding the part they play, a colony of ants forms a complex hivemind or neural network.
Ant Brain vs. Human Brain
Ants have a tiny brain and don’t possess a complex neural network like humans do. Because of their limitations, they are less smart than most other insects and have fewer abilities.
Ants, on the other hand, may learn by observation and accomplish things with relative ease as long as they stick to a few guidelines.
This new knowledge could help those who travel farther away from the colony find food sooner, for example, if you drop food near an anthill or on top of it where some workers can easily locate it but others may struggle to reach it.
Are Ants the Smartest Insect?
Ants are considered to be among the most intelligent. Bees, on the other hand, have been shown to observe, learn, and solve problems. They are often considered to be smarter than humans. Their ability to maneuver a wide range of blooms exemplifies this.
Ants are among the most cognitive insects, even if bees are more intelligent. Ants have been shown to use tools in one experiment, which is a common method of determining intelligence.
Liquids (both diluted and pure honey) and other objects like grains of soil, pine needles, and twigs were presented to ants in the laboratory. Sponge and paper were among the artificial items on hand.
The ants used the soil grains to absorb the diluted honey, then used the sponge to carry and transport the pure honey. They even tore the sponge into smaller pieces so they could carry it more easily.
That demonstrated a level of intelligence. Each option was tested again before paper and sponge were exclusively used, demonstrating learning capability.
Do ants feel pain when you squish them?
Ants feel irritated and, most likely, detect if they are hurt. They don’t feel pain. Ants don’t have emotions and have a different nervous system, so they can’t feel the pain that humans do.
Ants and insects have a decentralized nervous system composed of many independent ganglia, whereas mammals like us have a brain and a central nervous system. Ganglia are nerve clusters that function as smaller, simpler brains.
Even in young ants, ants are considered to be the world’s smartest insect with up to 250,000 neurons. The brains of these tiny creatures are unlike those of any other creature.
There is no way of knowing how the ant feels about the pain sensations that the signals provide. They are most likely unpleasant or at least undesirable.
No one can communicate the experience of being an ant in a manner that is understandable to human civilization because pain and suffering are subjective.
Can Ants get Brain Damage?
Because ant brains are so restricted in function, ants cannot get concussions or brain damage, unlike humans.
The exoskeleton of these creatures contains sensory hairs that are directly linked to their nerve system. All of these benefits allow them to sense a variety of alterations in their surroundings, communicate with other ants, and much more.
As a result, they will not feel pain when they are hurt because their brain is not fully developed, which is why they do not have feelings.
Since they don’t have pain receptors, this is also the reason they can’t experience any unpleasant feelings in their body. They may perceive that a portion of their body has been harmed, but they aren’t physiologically developed enough to experience any discomfort.
Yet, unlike humans, they have an independent nervous system that functions properly even when its brain is significantly damaged, allowing them to live for a long time and move around as the remainder of the nervous system continues to work normally until they die from the illness and infection.
Similarities Between the Ant Brain and Human Brain
The ant brain and the human brain have certain commonalities. Neurons, or nerve cells that use electricity to communicate with one other, make up both of them.
Sending chemical signals from one neuron to another across a distance is how they accomplish this. An axon terminal, also known as a synapse, is located at the end of each neuron.
The release of chemicals known as neurotransmitters into the space between two neurons, which causes electrical impulses to pass via these spaces in our brains similar to ants, occurs when a message reaches the conclusion.
As a result, when we learn something new, our experiences rewire our brains by strengthening some connections while weakening others depending on how often things occur together.
As a result, our and ant brains have comparable memory subsystems.
What Is a Hive Mind?
In contrast to individual understanding, hive mind theory emphasizes collective understanding. Bees are the origin of the term, which is now used to describe other highly social insects like ants.
The general population often understands it and portrays it as a solitary creature with linked brains who has no intelligence apart from the group. That’s not what it means or how insects work in reality.
Instead, a hive mind is the process of finding information as a group rather than as individuals. When a group is experiencing the same thing and acting as one, humans may have aspects of hive mind experiences.
Because of the influence that humans have over those they admire, they may imitate their actions. As a result, even though we do not have a hive mind, collective thinking does produce aspects of it.
Instead of “reproducing the wheel,” learning from other people’s experiences is a time-saving strategy. It may be more dangerous to merely do things because others do them.
Can Ants Regrow Their Brains?
Some research has shown that some female ants in a colony of ants (Harpegnathos saltator) may decrease in size before regrowing their brain. This is not a characteristic of all ant species.
A battle breaks out among some of the female worker ants to become the next queen when a queen ant from a colony of Harpegnathos saltator dies, according to scientists, with their brains shrinking and ovaries expanding.
This tournament can last many weeks, with the winning candidates developing a huge ovary and losing around a fifth of their brain size in the process at the conclusion of the battle.
In addition, they experience other hormonal alterations that prepare their bodies for maximal egg production, as well as reducing venom output.
Those who do not become the queen return to their usual duties as worker ants after failing to do so during the competition. Their brain size, however, regrows to its original size when they return to their former lives.
It is thought that in order to conserve energy, the brain of these animals shrinks, which may be related to the ability to breed.
This is similar to how newly fertilized queens ants lose their wings before establishing a colony, utilizing the flight muscles’ energy to lay eggs.
This is undoubtedly a remarkable finding, as it may pave the way for further investigations and findings on brain plasticity that may be utilized to improve the treatment of neurological disease in humans.
The brain of Harpegnathos saltator ants has been reported to be able to shrink and expand.
