Is the brain's network connected in the graph theoretic sense
In mathematics, a graph $G = (V, E)$ is connected if, given any pair of nodes $x, y$, there is a path $x\ldots y$.
The brain is of course an intractably large network and can be modeled with a ...

Do neurons with one axon only project to a single target neuron? [duplicate]
Pyramidal neurons (among others) only have one axon. Am I right to assume that this means they only project to one target neuron, or can this axon branch out into multiple sub-axons at some point, and ...

Question about How to assign the order of vertices of a pial surface in FreeSurfer
I'm a CIVET user but I recently started to use FreeSurfer.
As far as I know, for a surface from CIVET, its vertices are ordered by upsampling a polygon. So I could access downsampled surface by ...

Are there any sources that estimate the number of *unique* direct connections between neurons?
There are plenty of sources on the number of synapses the average neuron in some region of the brain has. However, its become clear that there is some degree of redundancy in these connections, where ...

How do the outer hair cells amplify the traveling wave?
Depending on the movement frequency, outer hair cells can stretch and contract, amplifying the amplitude of the traveling wave at the basilar membrane.
How can they do this exactly? what is the point ...

Deflection of the basilar membrane
The basilar membrane becomes thicker and heavier from the basal end to the apical upper end - this is why high frequencies are perceived in the lower range and low frequencies in the upper range.
But ...

What is the cochlear frequency response by number of hair cells?
I am trying to recreate the cochlea/basilar membrane response to sound and want to know how the hair cells are bucketed or binned by frequency, so an ideal list would be something like 10 kHz - 12 kHz:...
