[HTML][HTML] SORN: a self-organizing recurrent neural network

A Lazar, G Pipa, J Triesch - Frontiers in computational neuroscience, 2009 - frontiersin.org
Understanding the dynamics of recurrent neural networks is crucial for explaining how the
brain processes information. In the neocortex, a range of different plasticity mechanisms are …

Untangling perceptual memory: Hysteresis and adaptation map into separate cortical networks

CM Schwiedrzik, CC Ruff, A Lazar, FC Leitner… - Cerebral …, 2014 - academic.oup.com
Perception is an active inferential process in which prior knowledge is combined with sensory
input, the result of which determines the contents of awareness. Accordingly, previous …

[HTML][HTML] Epitranscriptomic signatures in lncRNAs and their possible roles in cancer

S Dinescu, S Ignat, AD Lazar, C Constantin, M Neagu… - Genes, 2019 - mdpi.com
In contrast to the amazing exponential growth in knowledge related to long non-coding RNAs
(lncRNAs) involved in cell homeostasis or dysregulated pathological states, little is known …

Nanocomposite foams based on flexible biobased thermoplastic polyurethane and ZnO nanoparticles as potential wound dressing materials

A Bužarovska, S Dinescu, AD Lazar, M Serban… - Materials Science and …, 2019 - Elsevier
In the present study biobased and soft thermoplastic polyurethane (TPU), obtained by
polymerization from fatty acids, was used to produce TPU/ZnO nanocomposite foams by thermally …

[HTML][HTML] Robust encoding of natural stimuli by neuronal response sequences in monkey visual cortex

…, A Peter, J Klon-Lipok, H Xuhui, A Lazar… - Nature …, 2023 - nature.com
Parallel multisite recordings in the visual cortex of trained monkeys revealed that the responses
of spatially distributed neurons to natural scenes are ordered in sequences. The rank …

[HTML][HTML] Graphene-related nanomaterials for biomedical applications

AI Lazăr, K Aghasoleimani, A Semertsidou, J Vyas… - Nanomaterials, 2023 - mdpi.com
This paper builds on the context and recent progress on the control, reproducibility, and
limitations of using graphene and graphene-related materials (GRMs) in biomedical applications…

Fading memory and time series prediction in recurrent networks with different forms of plasticity

A Lazar, G Pipa, J Triesch - Neural Networks, 2007 - Elsevier
We investigate how different forms of plasticity shape the dynamics and computational
properties of simple recurrent spiking neural networks. In particular, we study the effect of …

[HTML][HTML] Where's the noise? Key features of spontaneous activity and neural variability arise through learning in a deterministic network

C Hartmann, A Lazar, B Nessler… - PLoS computational …, 2015 - journals.plos.org
Even in the absence of sensory stimulation the brain is spontaneously active. This background
“noise” seems to be the dominant cause of the notoriously high trial-to-trial variability of …

[PDF][PDF] Cortical gamma-band resonance preferentially transmits coherent input

CM Lewis, J Ni, T Wunderle, P Jendritza, A Lazar… - Cell reports, 2021 - cell.com
Synchronization has been implicated in neuronal communication, but causal evidence remains
indirect. We use optogenetics to generate depolarizing currents in pyramidal neurons of …

Stimulus complexity shapes response correlations in primary visual cortex

M Bányai, A Lazar, L Klein… - Proceedings of the …, 2019 - National Acad Sciences
Spike count correlations (SCCs) are ubiquitous in sensory cortices, are characterized by
rich structure, and arise from structured internal dynamics. However, most theories of visual …
