vertex

This was practically confirmed using a vertex cover problem with 4096 vertices.

While place cells fire whenever an animal is in a specific location, grid cells fire only when the animal is at one of the vertices of a triangular lattice.

Deneb is apparently the faintest of the stellar triangle vertices, but don’t be fooled.

Two classes of shapes work, they proved: “boring parallelograms” and “surprising cyclic quadrilaterals,” cyclic meaning that all vertexes of a quadrilateral lie on a circle.

In the Blue Brain graph, for example, three neurons with all three synapses between them transmitting signals formed the vertices of a hollow triangle.
