Neural manifolds - The Geometry of Behaviour

‘Manifold’ means a topological space that locally resembles a Euclidean space in mathematics. The term ‘neural manifold’ has been used to refer to a broad set of geometric structures in neural populati‘on activity underlying various cognitive tasks, although these population structures in real neural data are often no longer technically ‘manifolds’ in a mathematical sense, mainly due to the presence of neural noise and but also often due to the sparse input sampling.
