- Movie S1
The right
C2 whisker was deflected briefly in a urethane-anesthetized mouse, and the evoked sensory response was imaged bilaterally
with voltage-sensitive dye. The movie was generated from an average of 20 stimuli.
- Movie S2
In
the same urethane-anesthetized mouse as in Movie S1, the left C2 whisker was briefly deflected, and the evoked sensory response
was imaged bilaterally with voltage-sensitive dye. The movie was generated from an average of 20 stimuli.

S3
Spontaneous activity across sensorimotor cortex was imaged with voltage-sensitive dye in a urethane-anesthetized
mouse while simultaneously recording the local field potential in motor cortex. The voltage-sensitive dye signal in M1 corresponds
closely to the local field potential (the sign of the LFP trace was inverted for ease of comparison with the VSD trace).
- Movie S4
The movement of the C2 whisker was filmed with a high-speed camera at 500 Hz in an awake
behaving mouse during an active touch sequence. Sensorimotor cortex was simultaneously imaged with VSD. At the time indicated
by the vertical dotted line, the whisker contacts the object evoking a spreading sensorimotor response, first in S1 and subsequently
in M1. The single trial imaging of cortical activity and the behavioral filming are matched frame-by-frame, synchronized through
TTL pulses.
- Movie S5
A C2 whisker stimulus passively applied during quiet wakefulness
evoked a large-amplitude response in both somatosensory and motor cortex accompanied by sensory-evoked whisker movement. The
single-trial imaging of cortical activity and the behavioral filming are matched frame-by-frame, synchronized through TTL
pulses.
