Function and Applications

Complete instrument set consisting of neuron unit, operating unit, computer interface, measureAPP software for data acquisition and analysis and diverse cables and adapters.

Benefits

• With the instrument set multiple experiments covering the topic "nerve cell" can be performed.
• Optional and simple upgrade available to perform additional experiments about nerve cell interactions and neuronal networks.

Equipment and Technical Data

Computer interface:

• 2 x SMARTsense voltage sensors with 2 voltage measurement inputs

• Operation with all mobile devices (iOS and Android) and Windows-based PCs

Operating unit:

• 4 output channels which generate "muscle and sense signals", also serves as supply power to operate up to 4 neuron units.

Neuron unit:

• Simulates a generalised nerve cell with an apical dendrite and its synaptic contacts, a cell body (soma) and a nerve fibre (axon) with myelin sheathes and a Ranvier's ring.
• The dendrite comprises exciting, inhibiting, presynaptic and Hebbian synapses which are marked by the corresponding colours of the sockets.
• The axons end in presynaptic buttons.
• These are represented together with a part of the (afferent) fibre providing the signal.
• The connection between the (efferent) axon of a neuron unit which leads away or the stimulus output socket of the operating unit and a synapse is established by means of a white cable which is inserted into the desired synapse socket.
• The yellow sockets serve for the derivation of the state of excitement of the simulated neuron.
• They are connected to a computer interface.
• The action potentials can be made audible with the aid of the integrated acoustic monitor.
• The turning knob "S"serves for setting the "firing threshold" of the neuron.

Other:

• All cables and adapters necessary for the experimental set-ups -Oscilloscope for action potential measurements

• Oscilloscope for action potential measurements
