Set Neurobiology with one nerve cell with Cobra SMARTsense

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
