Biological amplifier

Biological amplifier

Function and Applications

With the aid of this biological amplifier a wide range of electrophysiological experiments can be carried out on human beings, insects and earthworms.

The frequency range for the measurement can be pre selected to match the different biological ...

Stimuli generator

Function and Applications

The stimuli generator supplies squarepulses of variable amplitude and pulse width, as a single pulse or double pulse (at a variable interval).

Benefits:

• A simple push on the start button triggers either a single or a doubl ...

Neuro-simulator

Function and Applications

The neuron unit Neurosimulator simulates a generalised nerve cell with an apical dendrite and its synaptic contacts, acell body (soma) and a nerve fibre(axon) with myelin sheathes and a Ranvier's ring.

Benefits:

• The dendri ...
