How to avoid Electrical Noise in InVivo Electrophysiology recordings

Hi

Here we are working to establish Invivo Electrophysioloigy in Dorsal horn Neurons using Neurolog systems NL100 and Spike 2 Software , ( with band pass filter (20-1500 HZ) and amplified ( 5000X, Pre AMP NL104 Digitimer). 
 we are facing lot of noise in our recordings even after using Fraday cage and well grounded (0.2v)electrical sockets and faraday cage, animal preparation is grounded to stereotaxy base plate.

So where we are going wrong and what are other common problems that can be source of noise.

Can any one suggest us for the betterment of the experiment we planned for.

Here iam attaching the recording of rat spinal dorsal horn neurons please look in to the same anf forward your reply.

Thanking you
