How are Artificial Neural Networks and the Biological Neural Networks similar and different?

I've heard multiple times that "Neural Networks are the best approximation we have to model the human brain", and I think it is commonly known that Neural Networks are modelled after our brain. I strongly suspect that this model has been simplified,…

What activation function does the human brain use?

Does the human brain use a specific activation function? I've tried doing some research, and as it's a threshold for whether the signal is sent through a neuron or not, it sounds a lot like ReLU. However, I can't find a single article confirming…

How powerful a computer is required to simulate the human brain?

How much processing power is needed to emulate the human brain? More specifically, the neural simulation, such as communication between the neurons and processing certain data in real-time. I understand that this may be a bit of speculation and it's…

Is there research that employs realistic models of neurons?

Is there research that employs realistic models of neurons? Usually, the model of a neuron for a neural network is quite simple as opposed to the realistic neuron, which involves hundreds of proteins and millions of molecules (or even greater…

What makes the animal brain so special?

Whenever I read any book about neural networks or machine learning, their introductory chapter says that we haven't been able to replicate the brain's power due to its massive parallelism. Now, in modern times, transistors have been reduced to the…

Are convolutional neural networks inspired by the human brain?

The Deep Learning book by Goodfellow et al. states Convolutional networks stand out as an example of neuroscientific principles influencing deep learning. Are convolutional neural networks (CNNs) really inspired by the human brain? If so, how? In…

In 2016, can $1000.00 buy enough operations per second to be approximately equal to the computational power of a human brain?

In The Age of Spiritual Machines (1999), Ray Kurzweil predicted that in 2009, a \$1000 computing device would be able to perform a trillion operations per second. Additionally, he claimed that in 2019, a \$1000 computing device would be…

What is the importance of the endocannabinoid system for cognitive function?

The endocannabinoid system is a very important function of human biology. Unfortunately, due to the illegality of cannabis, it is a relatively new field of study. I have read a few articles about Google researching the role of dopamine in learning,…

Is there any paper, article or book that analyzes the feasibility of acheiving AGI through brain-simulation?

In my understanding, the mind arises from a physical system, the brain. I see that there is a big research under the topic of simulating physical systems efficiently (especially in quantum computing). Hence, in theory, we could achieve AGI by…

Are there any artificial neuromorphic systems which can mimic the brain?

I'd like to know whether there were attempts to simulate the whole brain, I'm not talking only about some ANN on microchips, but brain simulations.

Is it possible to build an AGI with neural networks on neuromorphic chips?

I read a lot about the structure of the human brain and artificial neural networks. Is it possible to build an AGI (or human-level AI) with artificial neural networks on neuromorphic chips, which would be divided into centers, like the brain is,…

Models of reward (possibly mimicking dopamine) in artificial neural networks?

How one can model physiological reward mechanisms occuring in the brain using artificial neural networks? E.g. are there efforts to use the notion of dopamine or similar substances in the artificial neural networks. Maybe introduction of the…

Are AI algorithms capable of self-repair?

Do AI algorithms exist which are capable of healing themselves or regenerating a hurt area when they detect so? For example: In humans if a certain part of brain gets hurt or removed, neighbouring parts take up the job. This happens probably because…

If we achieve sentience using mutable hardware, will it be possible to make a copy of that "brain" and its active state?

Hardware comes in two forms, basically: immutable, such as RAM, and mutable, such as FPGAs. In animals, neurological connections gain in strength by changing the physical structure of the brain. This is analogous to FPGAs whereby signal strength is…

Are my steps correct for a proper classification of a sick brain?

I have a dataset with MRI of patients with a specific disease that affects the brain and another dataset with MRI of healthy patients. I want to create a classifier (using neural networks) to classify if the MRI of a new patient shows the presence…
