ANNarchy: a code generation approach to neural simulations on parallel hardware

J Vitay, HÜ Dinkelbach, FH Hamker - Frontiers in neuroinformatics, 2015 - frontiersin.org
Many modern neural simulators focus on the simulation of networks of spiking neurons on
parallel hardware. Another important framework in computational neuroscience, rate-coded …

Emergence of attention within a neural population

NP Rougier, J Vitay - Neural Networks, 2006 - Elsevier
We present a dynamic model of attention based on the Continuum Neural Field Theory that
explains attention as being an emergent property of a neural population. This model is …

Working memory and response selection: a computational account of interactions among cortico-basalganglio-thalamic loops

H Schroll, J Vitay, FH Hamker - Neural Networks, 2012 - Elsevier
Cortico-basalganglio-thalamic loops are involved in both cognitive processes and motor
control. We present a biologically meaningful computational model of how these loops …

Does enhanced shape bias improve neural network robustness to common corruptions?

…, R Subramaniam, R Hutmacher, J Vitay… - arXiv preprint arXiv …, 2021 - arxiv.org
Convolutional neural networks (CNNs) learn to extract representations of complex features,
such as object shapes and textures to solve image recognition tasks. Recent work indicates …

Dysfunctional and compensatory synaptic plasticity in P arkinson's disease

H Schroll, J Vitay, FH Hamker - European Journal of …, 2014 - Wiley Online Library
In Parkinson's disease, a loss of dopamine neurons causes severe motor impairments. These
motor impairments have long been thought to result exclusively from immediate effects of …

The contribution of the basal ganglia and cerebellum to motor learning: A neuro-computational approach

J Baladron, J Vitay, T Fietzek… - PLoS computational …, 2023 - journals.plos.org
Motor learning involves a widespread brain network including the basal ganglia, cerebellum,
motor cortex, and brainstem. Despite its importance, little is known about how this network …

A distributed model of spatial visual attention

J Vitay, NP Rougier, F Alexandre - Biomimetic neural learning for …, 2005 - Springer
Although biomimetic autonomous robotics relies on the massively parallel architecture of the
brain, the key issue is to temporally organize behaviour. The distributed representation of …

Enhanced habit formation in Tourette patients explained by shortcut modulation in a hierarchical cortico-basal ganglia model

C Scholl, J Baladron, J Vitay, FH Hamker - Brain Structure and Function, 2022 - Springer
Devaluation protocols reveal that Tourette patients show an increased propensity to
habitual behaviors as they continue to respond to devalued outcomes in a cognitive stimulus-…

On the role of dopamine in cognitive vision

J Vitay, FH Hamker - International workshop on attention in cognitive …, 2007 - Springer
Although dopamine is one of the most studied neurotransmitter in the brain, its exact function
is still unclear. This short review focuses on its role in different levels of cognitive vision: …
