The extracellular microelectrode recording technique developed by David Hubei for his epochal studies of the cat visual system and further perfected by Eduard Evarts for his pioneering work on the cat motor system was easily applied to exploring the brain stem. There were two major obstacles that needed to be overcome to guarantee success, however. The first was movement not only was head movement itself a problem, but body movement also had to be limited because the targets were deep and located on the major axis of lateral and vertical head-on-neck movement. The second problem was identification of the neurons of interest. At the onset, no one knew that the modulatory elements would identify themselves both by their distinctive spike-to-spike firing pattern, but also—and this is the main point of the discovery—by their dramatic state dependent alterations of firing propensity.

Were sequestration a key element to progression to severe malaria and/or cerebral malaria then it is conceivable that immunotherapy might alter the dynamics of parasite clearance and be beneficial to the patient (Taylor et al., 1992). Adherence to individual receptors was blocked by monoclonal antibodies and synthetic peptides in in vitro adherence studies (Crandall et al., 1993) administration of anti-malaria immunoglobulin to children with mild malaria reversed sequestration in vivo and evidence of synthetic peptide (HPLQKTY) blocking of adherence in vivo was also reported (Crandall et al., 1993 and citations in Goldring, 2004). Reversal of sequestration was shown in a squirrel monkey model of malaria by administration of hyperimmune sera (David et al., 1983) and adherence of isolates from Malawi was reversed with a pool of local sera (Goldring et al., 1992). However, in a double-blind, placebo-controlled administration of antibodies as an adjunct to quinine there was no measurable effect on adherence and patient recovery was unaffected (Taylor et al., 1992).
