Carbon dioxide
increase of carbon dioxide in the tissues and the bloodstream
The strongest association is formed when we present the conditioned stimulus about half a second before the unconditioned stimulus.
threshold stimulus
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
yes rising CO2 level a stimulus to breathing infact respiration regulatory centers are apparantly insensitive to O2 concentration The sensitive tissue located in carotid artery, carotid labyrinth detects increased CO2 concentration and stmulates respiratory centers to induce breathing.
CO2
Increasing stimulation up to the maximal stimulus
just noticeable difference
mechanical stimulus
Concentration
Number of times the neuron fires
No, they actually decrease in amplitude as they move away from the stimulus point.
