Item no.: P4010711

Principle

Interactive learning and teaching system with one neurosimulator for up to 30 experiments covering nerve cells.

Tasks

  • use the nerve function model to study the following aspects of a nerve cell: intercellular potential, action potential, the different types of synapses.

What you can learn about

  • Comparison between low and high threshold and stimulus levels, membrane time constant and low pass filtering, low-pass filtering, excitatory synapse, depolarisation, temporal summation, spatial summation, synaptic amplification by terminal branches, effect of decreasing stimulus, Hebbian synapse, synaptic learning and forgetting, inhibitory synapse, hyperpolarization, spacial inhibitory-excitatory summation, veto synapse.

The system can be upgraded with a one, two or three additional neurosimulators to perform experiments about

  • nerve cell interactions (motoneuron signals with recurrent inhibition by Renshaw cell, motoneuron signals without recurrent inhibition, functional characteristics of Renshaw inhibition, lateral inhibition, contrast improvement, conditioned reflex, reversed stimulus succession does not bring about a conditioned reflex).
  • neural networks (transient, i.e. phasic responses: focus on visual sense, body clock, short-term memory, special anatomical circuits: cerebral cortex and sensoric learning, functional characteristic of a triad).
  • complex neural networks (direction selectivity by unilateral inhibition, self-calibration of paired sensory channels).
