Archerfish (Toxotes jaculatrix) can encode an abstract concept of number in relative numerousness judgements, without the influence of any continuous physical variables, including spatial frequency.

Relative to children and adults, adolescents placed greater weight on negative prediction errors during learning and these age-varying learning idiosyncrasies biased subsequent memory for information associated with valenced outcomes.
Dendritic calcium spikes translocate hippocampal place fields by inducing a non-Hebbian form of bidirectional synaptic plasticity that operates over a seconds-long timescale called behavioral timescale synaptic plasticity.
Short-ranged and random connectivity are sufficient to explain complex, long-range activity patterns observed in macaque motor cortex that are, moreover, flexibly adaptable to behavior.
Single-cell transcriptomes of larval zebrafish whole brain shed light on the multidimensional landscapes of transcription factors and post-transcriptional regulators in vertebrate whole-brain neuronal classification and revealed principles of how neuronal cell diversity develops and evolves.
Direct imaging of individual molecules of the tip-link protein PCDH15 in mouse stereocilia shows that it assembles as a dimer, forms complexes that span stereocilia, and occurs in clusters with multiple copies of the PCDH15 dimer.
pyControl is an open-source tool that makes it easy to specify complex behavioural tasks, run them at scale on low-cost hardware, and communicate task logic to other researchers.
