According to dynamical systems, psychiatric disorders can be seen as energy landscapes with peaks and valleys. OCD has deep valleys where neural activity gets stuck, while schizophrenia has shallow valleys that let neural activity roam too freely, connecting unrelated ideas. pic.twitter.com/Ajypur5XIM

Motor cortex generates outputs while keeping track of its place in a sequence. To do this, it must avoid intersections, such as the center of a figure-8, where it could get off-track. A majority of motor cortex prevents these intersections, rather than encoding motor variables. pic.twitter.com/mJ9DkkF5jg

Communication subspaces enable the brain to selectively send different signals to different brain regions. Here, neuron 3 computes the sum of neurons 1 and 2, whereas neuron 4 computes their difference. In this way, neurons 3 and 4 can trace out completely independent patterns. pic.twitter.com/9iz9nsiEoS
