phenomena include alterations in the interpretation of the patient s.<br />

surroundingssuch as deja vufearand dreaming states and the.<br />

reproduction of visual or auditory aspects of specific earlier.<br />

experiences.That patients report specific memories in response to.<br />

specific stimulation. These phenomena usually arise from tissue.<br />

showing epileptogenic dischargebut there is an asymmetry in their.<br />

occurrencestimulation of the right temporal lobe produces these.<br />

phenomena more frequently than does stimulation of the left temporal.<br />

lobewhich suggests that the right hemisphere has perceptual functions.<br />

not shared by the left.. Disruption of speech is a welldocumented effect<br />

of stimulation of. the left hemispherebut only recently has stimulation<br />

of the right. hemisphere been shown to disrupt behavior.Ojemann and<br />

his colleagues. reported that stimulation of the right hemisphere<br />

disrupts judgments. of line orientationlabeling of facial expressionsand<br />

shortterm. memory for faces.. Although language is usually located in<br />

the left hemispherein a. small percent age of peoplemost of them<br />

auditory system is not as completely crossed as the. visualbecause both<br />
