Neural and computational evidence reveals that real-world size is a temporally late, semantically grounded, and hierarchically stable dimension of object representation in both human brains and artificial neural networks.
Optogenetic climbing fiber activation regulates experience-dependent plasticity in the primary somatosensory cortex of mice, suggesting a role of the olivo-cerebellum in instructive signaling across brain regions.
Ripples maintain time-locked occurrence across the septo-temporal axis and hemispheres while showing local phase coupling, revealing a dual mode of synchrony in CA1 network dynamics.

Different locations of neurotransmitter release sites in axon-bearing and anaxonic olfactory bulb dopaminergic neurons allow self-inhibition only in anaxonic cells, showing how polarity differences create separate functional roles in sensory processing.
The retrieval-extinction paradigm elicits a short-term fear amnesia that differs in cue specificity, timescale, and dependence on thought-control ability from the long-term amnesia believed to be associated with memory reconsolidation.
