adding glutamate to a slice of the cat spinal cord maintained in a dish: - answer✔-causes
alternate bursting in left and right ventral roots
-mimics the effects on activity in the ventral roots of dorsal root stimulation
CPGs in the vertebrate spinal cord: - answer✔-can be switched on by sensory input
-can be activated by stimulation of the mesencephalic locomotor nucleus
-can be modulated by coordinating fibers from other CPGs
in a mesencephalic cat suspended on a treadmill, which of the following is true? - answer✔the
animal will walk faster as the stimulation current delivered to the MLn is increased
stimulation of cat mesencephalic locomotor nucleus should: - answer✔-produce a pattern of
walking, trotting and galloping as the current intensity is increased
-result in activation of spinal central pattern generators for locomotion
-result in an alternating pattern of activity in corresponding left and right ventral roots
-result in an alternating pattern of activity in alpha motor neurons innervating the left and right
legs
when a person is asked to perform a complex sequence of finger movements and brain activity is
recorded by PET - answer✔-primary motor cortex will show increased activity
-supplementary motor cortex show increased activity
