<p>Brodmann areas 21 is over the temporal lobe, encompassing most of the lateral temporal cortex. This region is also referred to as the middle temporal cortex. This region is linked to sentence generation and word processing, specifically:</p><p><ul><ul><ul><li>Word generation&nbsp;</li><li>Monitor speech&nbsp;</li><li>Repeating words&nbsp;</li><li>Complex sounds&nbsp;</li><li>Deductive reasoning&nbsp;</li><li>Categorization&nbsp;</li><li>Observe motion&nbsp;</li><li>Complex sounds&nbsp;</li><li>Mirror neuron system&nbsp;</li></ul></ul></ul></p><p>This area of the brain is vital for long term memory, like facts and events. The structures in the medial temporal gyrus include the hippocampus, the amygdala, brainstems and other regions critical for memory formation and storage.</p><p>This area also holds the primary auditory cortex which is involved in high level auditory processing, and the processing of speech and words. This is an area where auditory signals from the cochlea reach the cerebral cortex and are processed by the primary auditory cortex.&nbsp;</p><p>The ventral part of the temporal cortices are involved in high-level visual processing of complex stimuli such as faces and scenes, and the anterior parts are for object perception and recognition.&nbsp;</p><p>Damage in this areas would lead to disturbance of auditory sensation and perception, disturbance of selective attention of auditory and visual input, disorders of visual perception, impaired organization and categorization of verbal material, disturbance of language comprehension, impaired long-term memory, and altered personality and affective behavior (Kolb &amp; Wilshaw, 1990).</p><p style="text-align: center;"><img src="@@PLUGINFILE@@/ba-21.png" alt="" width="258" height="398" role="presentation" class="img-responsive atto_image_button_text-bottom"><br></p><p><br></p>
