Example Sentences:

(5) Movements of RF-vibrissae produced a burst of multiple discharges in S-TR neurons and single spike discharges followed by a prominent suppression of spontaneous discharges in VB neurons.
(6) The PSA frequency varied in relation to the difference between fast and slow vibrissa tremor, as reported previously.
(7) Responses of neurones to either physiological stimulation of hair and vibrissa follicle sensory afferents and to ionophoretically applied excitatory amino acids were challenged with the antagonists D-2-amino-5-phosphonovalerate (APV), kynurenate and gamma-D-glutamylaminomethyl sulphonate (GAMS).
(8) The following structures of the host brain were stimulated: ventrobasal complex and posterior thalamic nuclei, ipsilateral area of vibrissae representation in the sensorimotor cortex and contralateral barrel field.
(9) The vibrissae of rex are curved or bent and may break off; those of waved are a mixture of straight, curved, and bent hairs.
(10) These patterns of metabolic activity underscore the vertical and horizontal organization of the SmI vibrissa cortex and suggest that neurons located within the central core of a column have functional properties distinct from those located in zones where individual columns interface.
(11) The normal cytoarchitectonic pattern of barrels in layer IV of mouse SmI face cortex is altered by early damage to the mystacial vibrissae (Van der Loos and Woolsey, '73).
