Additional nerve cell

Product No: 65963-10

Function and Applications

Additional nerve cell unit to complement the Neurobiology Set.

Benefits:

In addition to the 13 experiments covering the topic "nervecell", with

one further nerve cell 8 additional experiments can be performed covering the topic "nerve cell interactions".
a second addditional nerve cell extends the scope to "neuralnetworks".
a third additional nerve cell adds two experiments covering "complex neural networks".
The 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.

Equipment and technical data:

The dendrite comprises exciting, inhibiting, presynaptic and Hebbian synapses which are marked by the corresponding colours of the sockets.
Here 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 must be connected to suitable measuring instruments (e.g.oscilloscope) or 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.
