Seeking experiments that are the basis of the 100-step limit
I've read many times of the 100-step limit: since people respond to most complex stimuli in under 500 ms, and neurons take about 5 ms (or more) to switch state in response to a new stimulus, the ...

What is the best network-based cognitive model to explain and predict political decision-making?
I would like to build a simple human-readable model based on connected concepts that can model how people - very approximately - represent and update their decision-making on a political subject as ...

Is there any correlation between conection and function?
I have been searching why different functions exist in even a similar structure cortex.
The first reason is differences in cortical neuron density.
The neuronal density contour plot (Fig. 1D) reveals ...

Functional vs. synaptic connectivity
I used to believe that connectivity is nothing but synaptic connectivity and thus a long-term concept: synapses grow and synaptic strengths change on rather large time scales. But recently I found ...

Modelling the Human Brain as a directed graph
A mathematician on the MathOverflow, Hans-Peter Stricker, recently(2016) considered the possibility that human brains may be modelled as directed graphs with neurons as nodes and synapses as edges. I ...

Are there any precise design principles for artificial connectomes or neural networks?
I've been reading about the openworm.org project. I've downloaded the code and run some simulations.
The people at OpenWorm have made an experiment where they setup a robot with the neural network of ...

Neurosurgically grown neural link between two brains?
I guess it's possible to surgically restore neural connection after a trauma (e.g. a severed hand can be reattached if done quickly).
And, from history of evolution of hominids, it seems that just by ...
