  • Title: The mescaline or strychnine spikes as a tool for physiological and pharmacological studies.
    Author: Ramos JG.
    Journal: Acta Physiol Lat Am; 1977; 27(1):16-30. PubMed ID: 616170.
    Abstract:
    The all-or-nothing spikes elicited by antidromic, afferent, or direct electrical stimulation of a cortical area treated with mescaline or strychnine were studied. These potentials are most probably originated in nonsynaptic dentritic membranes and their changes in amplitude and latency can be an index of the excitability of these structures. Several factors are considered as sources of error when measurements of such parameters are made to follow their changes in different experimental conditions. When these sources of error can be eliminated, the frequency, amplitude and latency of those spikes can be taken as an index of the variations in cortical excitability under some physiological conditions. Another use of these giant potentials can be for the study of humoral and pharmacological agents.
