The control of targeted reaching is thought to be shaped by distinct subtypes of local GABAergic inhibitory neurons in primary forelimb motor cortex (M1). However, little is known about their action potential firing dynamics during reaching. To address this, we recorded the activity of parvalbumin-expressing (PV+) GABAergic neurons identified from a larger population of fast-spiking units and putative excitatory regular-spiking units in layer 5 of the mouse forelimb M1 during an M1-dependent, sensory-triggered reaching task.

Indeed, some mechanoreceptors can detect even nanometer-scale movements. Movement is transformed into electrical signals via the gating of mechanically activated ion channels at sensory endings in the skin.

The assay is based on a polarity- and sequence-specific reverse transcription used to distinguish specifically between viral genomes (vRNA(-)), replicative intermediates (cRNA(+)) and viral messenger RNAs (vmRNA(+)) of segments 4 (HA), 6 (NA), 7 (M) and 8 (NS) during the life cycle of influenza virus. Synthetic viral RNAs used as reference standards for validation and quantitation were prepared for each viral RNA type and segment.
