Document Summary

The evidence form extrasensory perception (esp) is weak or nonexistent. Howard hughes in sensory exotica (2000) points out that humans and other animals have several internal sensory systems in addition to the 5 primary senses. The evidence for a 6 th sense is purely anecdotal and isn"t scientific. Honorton (1994) in his study, a "sender"" in a soundproof booth focused on randomly generated images, and a receiver in another room tried to sense the sender"s imagery. The receiver was asked to choose among 4 alternatives, one of them being correct. They were right about 33% of the time. Hearing: auditory neurones in the thalamus extend their axons to the primary auditory cortex (a1), in the temporal lobe. Neurones in this region code the frequency of auditory stimuli. A1 respond best to lower frequencies, whereas those in the front of the a1 respond to higher frequencies.
