23. Section 5
TIME PERCEPTION

24. -- All of these represent the same speed (m/s)
-- bigger distance -- faster time!
compression of space = compression of time!

29. Johannes Műller 1826
DOCTRINE OF SPECIFIC NERVE ENERGIES
“regardless of how a receptor is stimulated it produces only one kind of sensory experience”

31. WHEN DO CELLS PRODUCE ACTION POTENTIALS?
1 -- electrical stimulation (artificial depolarization)
2 -- spatial and temporal integration of EPSPs and IPSPs across the neurone’s membrane resulting in the neuronal threshold being reached.
Generator potential
3 -- sensory stimulation (transduction)
mechanical (cytoskeleton)
chemical (receptors, second messengers)
light (hyperpolarization)
