The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.
LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.
The first patch-clamp recordings from single cerebellar granule cells during locomotion reveal that the entire step sequence can be predicted from both excitatory synaptic input and output spikes from a single neuron.
Odor conditioning induces two changes in olfactory neurons: non-associative sensory adaptation to odor history, and associative, bidirectional changes in behavioral output that are oppositely regulated in aversive and appetitive learning.
A new system for tagging activated neuronal population offers multiple advantages over existing systems based on immediate early genes, including greater sensitivity and specificity, and suitability for easy application in species other than mice.
