A decoding-based, state-space reconstruction reveals that neurons in macaque IT cortex change the structure of their collective attractor dynamics depending on task contexts.

Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).
The neural population of the Aplysia's pedal ganglion are a low-dimensional spiral attractor, and the parameters of the attractor directly define the properties of the Aplysia's escape locomotion behaviour.

Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
Two evolutionary distant insect species share a common head direction circuit with subtle differences in neuronal morphologies that result in distinct circuit dynamics adapted to each species’ ecology.
Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.
The first biology-constrained neural model of insect navigation guidance systems was explained including path integration, visual homing and route following, and their optimal coordination.
