terminals are adjacent, while the ground terminal is further away. The positive terminal
is distinguished by a slightly recessed surround.
Signal Input (−)
Ground/Reference
Signal Input (+)
Connections are made to the Neuro Amp EX front-end using the supplied Neuro Amp
EX headstage and connectors (microelectrodes are not supplied). The headstage cable
plugs into the five-pin input socket on the front panel: the pin arrangement ensures that
polarity is correct. Only use the supplied Neuro Amp EX headstage as others may not
meet safety requirements.
To Electrodes To Neuro Amp EX
Six male gold plated miniature connectors or pins are supplied with the headstage.
These can be crimped or soldered to standard metal microelectrodes, such as
tungsten, stainless steel or platinum, to allow you to construct electrodes to suit your
requirements.
Recording Technique
When conducting research using the Neuro Amp EX, it is important to ensure that you
use correct preparation and recording techniques. It is important to understand the
types of problems that can occur, how they manifest, and what can be done to remove
them or to minimize their eff ect. Potential problems may arise due to aliasing, frequency
distortion, saturation, ground loops, electromagnetic fields, electrode contact and
motion artifacts. Many of these are discussed in “Preventing Problems” on page 14.
See the section below for discussion of preventing artifacts due to poor electrode
contact and subject movement.
