I have been unable to find drawings or photos of the brains upon which Broca and Wernicke based their descriptions of motor and sensory aphasias . 72.75.96.28 21 : 18, 25 September 2007 ( UTC ) superiorolive

Recent classification schemes adopting this approach, such as the " Boston-Neoclassical Model ", also group these classical aphasia subtypes into two larger classes : the nonfluent aphasias ( which encompasses Broca's aphasia and transcortical motor aphasia ) and the fluent aphasias ( which encompasses Wernicke's aphasia, conduction aphasia and transcortical sensory aphasia ).
