"Neural Integrator" in the Oculomotor System.

The oculomotor neural integrator uses a behavior-related coordinate system.

Coordinate systems are a central issue in computational neuroscience: are they explicitly represented at some reductive level of brain function, and if so, are they only trivial products of associated anatomic geometries? This investigation examined these questions in the neural network that holds eye position, the so-called oculomotor integrator. Since neural activity in the integrator is beha...

An efficient learning model for the neural integrator of the oculomotor system

Online Learning in an Oculomotor Integrator

The oculomotor neural integrator is a brainstem nucleus that stores the short term memory of eye position during gaze holding. This neural integrator is believed to perform temporal integration of transient eye velocity input using positive feedback. Such models of integration are known to suffer from a fine-tuning problem [9] since changes in the amount of feedback by less than 10% can de-tune...

Encoding of eye position in the goldfish horizontal oculomotor neural integrator.

Monocular organization of the goldfish horizontal neural integrator was studied during spontaneous scanning saccadic and fixation behaviors. Analysis of neuronal firing rates revealed a population of ipsilateral (37%), conjugate (59%), and contralateral (4%) eye position neurons. When monocular optokinetic stimuli were employed to maximize disjunctive horizontal eye movements, the sampled popul...
