Sensory experience steers representational drift in mouse visual cortex

J Bauer, U Lewin, E Herbert, J Gjorgjieva… - bioRxiv, 2023 - biorxiv.org

Degraded tactile coding in the Cntnap2 mouse model of autism

HC Wang, DE Feldman - Cell Reports, 2024 - cell.com
Atypical sensory processing is common in autism, but how neural coding is disrupted in
sensory cortex is unclear. We evaluate whisker touch coding in L2/3 of somatosensory …

Balancing stability and plasticity in continual learning: the readout-decomposition of activation change (RDAC) framework

D Anthes, S Thorat, TC Kietzmann, P König - arXiv preprint arXiv …, 2023 - arxiv.org
Continual learning (CL) algorithms strive to acquire new knowledge while preserving prior
information. However, this stability-plasticity trade-off remains a central challenge. This …

[HTML][HTML] Non-spatial hippocampal behavioral timescale synaptic plasticity during working memory is gated by entorhinal inputs

CC Dorian, J Taxidis, P Golshani - bioRxiv, 2024 - ncbi.nlm.nih.gov
Behavioral timescale synaptic plasticity (BTSP) is a form of synaptic potentiation where the
occurrence of a single large plateau potential in CA1 hippocampal neurons leads to the …

Semantic plasticity across timescales in the human brain

SH Solomon, K Kay, AC Schapiro - bioRxiv, 2024 - biorxiv.org
Our representations of the world need to be stable enough to support general knowledge
but flexible enough to incorporate new information as our environment changes. How does …

Deep learning-based location decoding reveals that across-day representational drift is better predicted by rewarded experience than time

KM Freud, N Lepora, MW Jones, C O'Donnell - bioRxiv, 2024 - biorxiv.org
Neural representations of space in the hippocampus and related brain areas change over
timescales of days-weeks, even in familiar contexts and when behavior appears stable. It is …
