In this study, we propose unsupervised learning of the lateral inhibition structure through inhibitory spike-timing dependent plasticity (iSTDP) in a computational model for multivariate data processing inspired by the honeybee antennal lobe. After exposing the network to a sufficient number of input samples, the inhibitory connectivity self-organizes to(More)
The insect olfactory system is capable of classifying odorants by encoding and processing the neural representations of chemical stimuli. Odors are transformed into a neuronal representation by a number of receptor classes, each of which encodes a certain combination of chemical features. Those representations resemble a multivariate representation of the(More)
Single-unit recordings suggest that the midbrain superior colliculus (SC) acts as an optimal controller for saccadic gaze shifts. The SC is proposed to be the site within the visuomotor system where the nonlinear spatial-to-temporal transformation is carried out: the population encodes the intended saccade vector by its location in the motor map (spatial),(More)

Saccades are rapid and ballistic eye-head gaze shifts between points of interest in the visual field. They are crucial for gathering high-resolution visual information. The midbrain superior colliculus (SC) generates saccadic eyemovement commands for downstream oculomotor circuits. It contains an eye-centered, gaze-motor map that relates the location of a(More)
Conditioned behavior as observed during classical conditioning in a group of identically treated animals provides insights into the physiological process of learning and memory formation. However, several studies in vertebrates found a remarkable difference between the group-average behavioral performance and the behavioral characteristics of individual(More)
