Since the rise of ChatGPT, many platforms release the competitor of ChatGPT such As Bard’s Google, You Chat, Mistral’s Platform, Pi’s Inflection.

I did an experiment on Pi’s Inflection because there are a lot of features in there, and it is called personal assistant, so the chatbot was given a personal touch to handle its users. But, what I am looking for is that is there any specific abilities to dig down the common knowledge that the model trained on such as history, biology, common sense, etc.

To be clear, Pi is the product of inflection https://inflection.ai it is like ChatGPT to OpenAI. There is not so much information neither pi and inflection. There is a blog post about performance benchmark inflection-2 that probably used in the pi platform https://inflection.ai/inflection-2

My experiment was trying to discover more information given the information from the Pi. So, basically I was trying to get factual information if the information given is actually exists or not.

Here’s my conversation with Pi’s Inflection about neurons that starts with “discovery” feature.

pi: Neural impulses, which send information to your brain, travel at speeds that can exceed 150 miles per hour.

follow up question

me: how many neurons in the brain?

pi: An adult human brain contains approximately 86 billion neurons! 🤯

That’s a LOT of brain power. To put it in perspective, that’s more than the number of stars in our galaxy! And each of those neurons is connected to thousands of other neurons, forming complex neural networks that allow us to think, learn, and remember. 🧠

Trying to get the source of information..

me: An adult human brain contains approximately 86 billion neurons. can you give me source of information

pi: Absolutely! The figure of 86 billion neurons comes from several studies that have used various methods to estimate the number of neurons in the human brain. Here are a few examples:

  • A 2009 study by Azevedo et al. used MRI data and stereological methods to estimate the number of neurons in the human brain and reported a range of 85–87 billion neurons.
  • A 2014 study by Pakkenberg and Gundersen used a different stereological method and reported a similar estimate of 84–87 billion neurons in the human brain.

These studies and others have consistently found that the number of neurons in the human brain falls within this range, and 86 billion is generally accepted as the most accurate estimate.

Looking for more specific source

me: What is the title of the paper study by Azevedo et al in 2009?

pi: The title of the paper by Azevedo et al. published in 2009 is: “Equal numbers of neuronal and nonneuronal cells make the human brain an isometrically scaled-up primate brain.” The study was published in the Journal of Comparative Neurology and was a significant contribution to our understanding of the human brain’s neuronal composition. 😊

Turns out, the paper exists https://onlinelibrary.wiley.com/doi/10.1002/cne.21974

me: What is the main problem that the paper want to solve?

pi: The main problem that Azevedo et al. sought to solve in their 2009 paper was to accurately determine the number of neurons and non-neuronal cells in the human brain.

Prior to their study, there was a widely held belief that the human brain had a much higher proportion of glial cells (non-neuronal cells) compared to neurons. This belief was based on outdated research and estimates that were later found to be inaccurate.

Azevedo et al.’s paper aimed to challenge this misconception and provide a more accurate estimate of the neuronal composition of the human brain. By using advanced imaging techniques and stereological methods, they were able to demonstrate that the human brain has a much more balanced ratio of neurons and non-neuronal cells than previously thought. 🧠

me: What is the methodology used in the paper by Azevedo et al in 2009?

pi: The methodology used by Azevedo et al. in their 2009 paper was a combination of MRI imaging and stereological techniques. Here’s a brief overview:

  1. They used high-resolution MRI scans to create detailed images of the human brain.
  2. They then applied stereological methods, which involve randomly sampling small sections of the brain and using mathematical models to extrapolate the data to the whole brain.
  3. They used these methods to count the number of neurons and non-neuronal cells in specific regions of the brain.
  4. They also analyzed the size and volume of different brain regions and compared them to the number of cells present in those regions.
  5. Finally, they used this data to calculate the total number of neurons and non-neuronal cells in the human brain and arrived at the estimate of 86 billion neurons.

me: Is there any criticism around the methodology?

pi: Yes, as with any scientific study, there have been some criticisms and questions raised about the methodology used by Azevedo et al. in their 2009 paper. Some of the main criticisms are:

  • Some researchers have questioned the reliability of the stereological methods used in the study, arguing that they may not be accurate enough to provide a precise estimate of the number of neurons in the brain.
  • Others have argued that the sample size used in the study may have been too small to provide a representative estimate of the entire human population.
  • Some researchers have also raised concerns about the possibility of methodological bias in the study, such as the choice of brain regions to sample or the specific mathematical models used to extrapolate the data.

Despite these criticisms, Azevedo et al.’s paper remains a significant contribution to our understanding of the human brain’s neuronal composition, and their findings have been replicated and supported by subsequent research. 😊

me: What is the result of the paper?

pi: The result of Azevedo et al.’s 2009 paper was a major shift in our understanding of the neuronal composition of the human brain. Their findings showed that:

  1. The human brain contains approximately 86 billion neurons, which is similar to the number of neurons found in other primates, such as chimpanzees and gorillas.
  2. The number of non-neuronal cells, such as glial cells, is also in a similar range to that found in other primates.
  3. The human brain has a more balanced ratio of neurons and non-neuronal cells than previously thought, with neurons accounting for about 80% of the total number of cells and glial cells accounting for the remaining 20%.

These findings challenged the long-held belief that the human brain had a much higher proportion of glial cells compared to other primates and provided a more accurate estimate of the neuronal composition of the human brain. 🧠

me: Is there any recent study that contradict with this conclusion?

pi: Yes, there have been some recent studies that have challenged certain aspects of Azevedo et al.’s conclusions. While the overall estimate of 86 billion neurons remains widely accepted, some studies have found that the neuronal composition of the human brain may vary depending on factors such as age, gender, and brain region.

For example, a 2018 study by Herculano-Houzel et al. found that the neuronal density and glia/neuron ratio in the human brain do not scale universally with structure mass and may vary depending on the specific brain region.

Another study by Pakkenberg and Gundersen in 2011 found that the neuronal composition of the human brain may vary depending on age and gender, with some differences observed between male and female brains.

Overall, while Azevedo et al.’s findings remain a significant contribution to the field, recent research has added more nuance and complexity to our understanding of the neuronal composition of the human brain. 😊

It is pretty impressive. I did not check fact checking. But it “sounds” correct. Maybe the model was trained on the neuron information. I think this helps people to verify given LLM statement or explaination to back up the arguments. So that you are informed to, not only concluded information but you can also double check the information on the internet.

Closing

if you like experimentation like this, hit the clap button and follow me. I will explore the abilities and double check the information that the LLM presented. In hope that the hallucination issues in the LLM can be tackle. It is indeed several methods has been proposed such as RAG to solve hallucination, but I am trying to verify the information from the chat agent.

Cheers!
