** P2C sensory connection [#we8d5564]
- Objective: Analysis of the connection between P2C sensory system
- Another objective: Receptive Field Induction
- Basic Idea
-- Subject: rat
-- Electrodes: FHC(PNS/CNS), Cuff(CNS)
-- Mechanically stimulate receptors to record signals in S1cx
-- Electrically stimulate peripheral fibers to record signals in S1cx
-- Simultaneous stimuli appied to peripheral / centeral sensory systems
- Experiment 1 (at least 2 trials)
-- Anesthetized
-- Search for a receptive field corresponding to the limb~
(Using automatic mechano-stimulator device?)
-- Mechanically stimulate skin receptors in the limb recording a response in S1c
x
-- Electrically stimulate peripheral fibers with a cuff / FHC electrode recordin
g a response in S1cx
- Experiment 2 (at least 3 trials)
-- Anesthetized
-- Insulate an electrode in S1 area
-- Record cortical signals while peripheral receptors/nerves are stimulated
-- Simultaneously stimulate skin receptors mechanically or peripheral nerves ele
ctrically (continue for more than 30 mins.)
-- Record cortical signals again; expecting the correlation has increased
