In rodents and primates, there are two subtypes of parvalbumin-expressing interneurons that provide novel substrates for selective inhibition in the striatum.
The rhythms generated by the stomatogastric and cardiac ganglia of the Jonah crab are surprisingly robust but differentially sensitive to acute changes in extracellular pH from pH 5.5 to 10.4.
Two regions of the frontal lobe – the anterior cingulate cortex and, unexpectedly, the dorsolateral prefrontal cortex – show coordinated rhythmic activity during REM sleep.
Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.
While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
A new paradigm of DNA methylation mediated gene activation and chromatin remodeling provides a general framework to dissect the biological functions of DNA methylation readers and effectors.
Neuroimaging provides novel insights into how the motor system represents sequences of actions by automatically separating their spatial and temporal features for flexible skill production.
