[Effects of tanycytes transplantation on the motor function score and rubrospinal motor evoked potentials of adult rats after spinal cord completely transected].

Objective: To determine whether tanycytes be able to support the regeneration of completely transected spinal cord in adult rats.

Methods: Subcultured tanycytes was transplanted into completely T8 transected spinal cord using the untranslated completely transected rats as control. After transplantation the rubrospinal motor evoked potentials were recorded below the injury level at the end of 12th week, assistant by Basso-Beatie-Bresnahan locomotor rating scale and histology method.

[Relationship between graded spinal cord injury and rubrospinal MEPs in rats].

Aim: To explore an accurate neurophysiological technique that demonstrates small functional differences after spinal cord injury and assesses therapeutic interventions.

Methods: A modified weight drop (WD) technique was used at T8 in rats to build graded spinal cord injury model. Rubrospinal MEPs were recorded at T13 epidurally to monitor spinal cord function in end week 4 after graded spinal cord injury.

[Excitatory postsynaptic potential evoked by stimulation of the ventrolateral region of the cerebellum in crucian carp Mauthner cell].

In the present experiments, the characteristics of the electrical responses to stimulation of the cerebellum in crucian carp Mauthner cell were explored with microeletrode intracellular recording technique. A composite excitatory postsynaptic potential (cerebellum-evoked EPSP) could be induced from the soma, the ventral dendrite and the proximal end of the lateral dendrite in crucian carp Mauthner cell (M-cell) on either side by stimulation of the ventrolateral region of the cerebellum. The cerebellum-evoked EPSP presented characteristics of relatively short latency (0.
