Cell-type-specific circuit analysis reveals a highly polysynaptic pattern of excitatory feedforward connections along the somatosensory-to-motor loop, from cuneate via VPL thalamus to S1 and M1 cortex and corticospinal neurons.
aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.
Somatostatin interneurons are novel mediators of serotonergic modulation in entorhinal cortex via activation of 5-HT2A receptors, a receptor involved in the etiology of different psychiatric disorders.
Hippocampal and prefrontal neuronal populations form slow behavioral-timescale (~seconds) and fast cognitive-timescale (~100 ms) sequential activity patterns as theta and replay sequences, which play distinct yet cooperative roles in memory-guided decision-making.
Theory explains how transport of gene expression vortices by cell advection may cause intermingled defective and normal segments along the body axis during resynchronization experiments in the zebrafish segmentation clock.
