Energetically efficient learning in neuronal networks (2023)
Journal Article
Pache, A., & van Rossum, M. C. (2023). Energetically efficient learning in neuronal networks. Current Opinion in Neurobiology, 83, Article 102779. https://doi.org/10.1016/j.conb.2023.102779

Human and animal experiments have shown that acquiring and storing information can require substantial amounts of metabolic energy. However, computational models of neural plasticity only seldom take this cost into account, and might thereby miss an... Read More about Energetically efficient learning in neuronal networks.

Competitive plasticity to reduce the energetic costs of learning (2023)
Working Paper
van Rossum, M. C. Competitive plasticity to reduce the energetic costs of learning

The brain is not only constrained by energy needed to fuel computation, but it is also constrained by energy needed to form memories. Experiments have shown that learning simple conditioning tasks already carries a significant metabolic cost. Yet, le...

Lazy learning: a biologically-inspired plasticity rule for fast and energy efficient synaptic plasticity (2023)
Working Paper
Pache, A., & Van Rossum, M. (0000). Lazy learning: a biologically-inspired plasticity rule for fast and energy efficient synaptic plasticity

When training neural networks for classification tasks with backpropagation, parameters are updated on every trial, even if the sample is classified correctly. In contrast, humans concentrate their learning effort on errors. Inspired by human learnin...

Rule Abstraction Is Facilitated by Auditory Cuing in REM Sleep (2023)
Journal Article
Pereira, S. I. R., Santamaria, L., Andrews, R., Schmidt, E., Van Rossum, M. C., & Lewis, P. (2023). Rule Abstraction Is Facilitated by Auditory Cuing in REM Sleep. Journal of Neuroscience, 43(21), 3838-3848. https://doi.org/10.1523/jneurosci.1966-21.2022

Sleep facilitates abstraction, but the exact mechanisms underpinning this are unknown. Here, we aimed to determine whether triggering reactivation in sleep could facilitate this process. We paired abstraction problems with sounds, then replayed these... Read More about Rule Abstraction Is Facilitated by Auditory Cuing in REM Sleep.

Estimating the energy requirements for long term memory formation (2023)
Working Paper
Girard, M., Jiang, J., & van Rossum, M. C. Estimating the energy requirements for long term memory formation

Brains consume metabolic energy to process information, but also to store memories. The energy required for memory formation can be substantial, for instance in fruit flies memory formation leads to a shorter lifespan upon subsequent starvation (Mery...
