With leathern girdle braced;
For all might see the bottlenecks
Still dangling at his waist.

In science:

Crystallographers are now solving the three-dimensional structure of proteins at the rate of one or more per day. A bottleneck is the difficulty of growing high-quality crystals for X-ray analysis.
Phase Behavior of a Simple Model for Membrane Proteins
This bottleneck, path P which divides the system in two parts: sites connected to the sink and sites connected to the source, is the global minimum cut of the graph and the sum of the capacities belonging to the cut PP cij equals the maximum flow, and is smaller than of any other path cutting the system.

This kind of bottleneck is what the quantum-physics-based theory predicts: the bottleneck is precisely the single linear sequence of mind-brain quantum events that von Neumann-Wigner quantum theory is built upon.
Quantum theory and the role of mind in nature
Pashler [p. 279] describes four empirical signatures for this kind of bottleneck, and describes the experimental confirmation of each of them.
Quantum theory and the role of mind in nature
Pashler [p. 308] notes that the bottleneck is undiminished in split-brain patients performing two tasks that, at the level of input and output, seem to be confined to different hemispheres.

The fifth condition prevents us from using a sequence of approximations in which the bottlenecks become increasingly severe with n; in particular, it implies that each Dn is connected.

We assume that the ‘bottleneck’ stages of the (bound) binary shrinking occur for separations a < ah ; during a galactic merger, after a dynamical friction timescale, we place the BH pair at ah and let it evolve.

We show that monotone properties for this class of graphs have sharp thresholds by reducing the problem to bounding the bottleneck matching on two sets of n points distributed uniformly in [0, 1]d .
